It is a reported bug as you can see here: Ubuntu bug-launchpad As you can see in the Bug-Track-Comment, the Bug has been fixed for apache2, but has not been added to the Ubuntu repo yet: John Pye (jdpipe) wrote on 2014-09-04: #9 This bug is resolved by modifying a new 14.04 server to install the apache2 packages from ...

When the system boots and the harddrive is full, nothing can write to /tmp. So during init a tmpfs is created and mounted. This way your system can safely boot, because it can write to /tmp. Free up disc space, and reboot your machine. (Or simply unmount /tmp, if you are sure nothing uses it). Setting this value to 0 disables the setup., which I would ...

Eventhough the whole story sounds kind of weird (usb should be visible with fdisk -l for instance), I have come across problems trying to boot usb 3.0 pendrives in old machines. While USB 2.0 devices boot on those machines without any problem new devices doesn't. So the question is... is your USB 2.0 and his 3.0? If that is the case and your school's ...

Identical flash drives? Some years ago I had a 2 gB flash drive that I could not make boot, I thought I was doing something wrong, but the identical steps on another UFD did make a bootable drive .. I tried more than 1 method, Unetbootin and grub I think

Sometimes my system gets freezed You needs to figure out what's triggered the freeze, try tail /var/log/dmesg or journalctl -f get ERR logs how to fix this? You can try restart Xserver, instead of power cycle your machine. Using keyboard combination ctrl+art+backspace or using GUI implements or killall X (you ought to start Xserver at ...

The simplest thing I can imagine here is to use a second SSH session to forward a named FIFO. I'm assuming you have a tmp/ in your home dir; feel free to keep the FIFO wherever you like. local$ ssh me@remotehost 'mkfifo ~/tmp/alert_fifo ; while cat ~/tmp/alert_fifo ; do : ; done' | \ while read icon_name text ; do notify_send --urgency=low -i ...

And now for the Ubuntu answers. This is an Ubuntu Linux question, and version 15 is now released. The Ubuntu world now has systemd. But even before version 15 the Ubuntu world had upstart. There really isn't a reason to write System 5 rc scripts; and there is certainly no good reason for starting from there. Both upstart and systemd do all of the ...

Currently, there is no driver for Mac cameras. There is a kernel.org bug open here, and a driver is under development (but not yet stable) here.

Fixed my own problem. Downloaded the newest version of crouton and issued sudo sh ~/Downloads/crouton -u -n chrootname and everything's back to normal.

-mtime N means files whose age A in days satisfies N ≤ A < N+1. In other words, -mtime N selects files that were last modified between N and N+1 days ago. For example, -mtime 1 selects files that were modified between 1 and 2 days ago. To select files that were modified in the last day (as in, the last 24 hour period), use -mtime 0. -mtime -N means files ...

To find files that have been modified a certain days ago, it is better to use -mmin instead of -mtime as the latter will ignore any fractional part. So, 1 day 23 hours is also treated as 1 day. From man find: -atime n File was last accessed n*24 hours ago. When find figures out how many 24-hour periods ago the file was last accessed, any ...

1) Desktop has a set of utilities tied to it, e.g., in kde you have kate as text editor, while in unity it's gedit. Theme only alters look of windows or icons 2) Distro comes with default desktop but is not limited to default one. I use Ubuntu, but I've been using openbox, blackbox, gnome, kde(which is default in kubuntu), lxde, and motif, interchangeably. ...

The first thing to try is to press Ctrl+Alt+F1. If the GUI is frozen but the keyboard driver is still responding, this will switch to a text console. You can log in to that text console and access your system and try to solve the problem. You can return to the GUI screen with Ctrl+Alt+F7 (some distributions may use a different number). If that doesn't work, ...

A pedantic note on an old post: the contents of /etc/network/interfaces will tell you how the interfaces MAY have been managed at boot (or after running 'service networking restart'). It is not definitive. It does not tell you how a given interface was assigned at any given moment. For example, given a DHCP managed interface I can easily kill dhclient and ...

When running a command during boot, we don't necessarily have access to the env for that command. I needed to use the fully qualified name for that command.

If you can still reach a console or terminal, maybe you could try this solution. Otherwise I believe sebelk's solution is probably a good start. If killing the X server is not sufficient and you can't reboot properly the machine, then in the same idea as sebelk, you could at least try to raise elephants to reboot more properly.

Try with: sudo su echo 1 > /proc/sys/kernel/sysrq Then press the keystroke Alt+PrtScr+K, this could kill your X session.

It seems the virtual interface will not be RUNNING until a software is attached to it. As soon as my program (the simpletun.c example) attached to the interface, every thing became OK.

I don't know this is the right way or best solution but it works without NAT. The network topology is the same. We have one physical NIC (em1) and multiple IP for every container. Maybe later i can buy a subnet. But for now i'll buy 4 - 5 IPs. ------------------- | INTERNET | ------------------- ...

I've had to deal with this a lot, and I used to teach a few classes where students needed to work from Windows machines. I'll describe two methods, and you decide what you like best. Also, warning: I am not a Windows user, I just provide support for them when they need to work with Unix :). Use WinSCP (http://winscp.net/eng/download.php) WinSCP is just a ...

In similar cases, I've used WinSCP. It's a Windows SCP client that allows you to browse the Linux file system graphically and scp files back and forth between the 2 machines. Available here : http://winscp.net/eng/index.php

You're doing this the very hardest way, but here you go: Get the wonderful pscp program. I'm not a Windows person at all so all I can tell you is put pscp.exe in your %path%. On the Windows machine, change directory to C:\Users\MyUser\Downloads On the Windows machine: pscp test.c odroid:test/ You'll probably have to type in your Ubuntu password. On the ...

I would say the most generally true answer is "no, you cant". There are various methods which may help in certain cases and these have been suggested already but these all seem to miss how this situation actually came to be. In truth, if you are using a custom kernel, that kernel can do anything, including hiding its presence or appearing to be a different ...

Sure, just check whether dpkg knows about it. First check the kernel version you are running. uname -a Linux orwell 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u2 x86_64 GNU/Linux Then tell dpkg to search for the kernel image file in the dpkg database. dpkg -S /boot/vmlinuz-3.2.0-4-amd64 linux-image-3.2.0-4-amd64: /boot/vmlinuz-3.2.0-4-amd64 Or, better, ...

Minimally, uname -r will give the kernal version, such as 3.18.6. However, when the kernel is compiled, an additional string can be configured in and attached to that and the distros usually do this to indicate their own patch level (after a dash) and flavour, such as 3.18.6-32-generic. That's one clue; obviously using your own string when you create a ...

Same as any other sudo apt-cache policy linux-generic is the version installed though the package manager and uname -r compare the versions for me its linux-generic: Installed: 3.19.0.15.14 Candidate: 3.19.0.15.14 and 3.19.0-15-generic which indicate the same version

Don't know a solution for shortcuts, but for the indicators: search for files beginning with "indicator" in /etc/xdg/autostart, edit with admin rights and add "Pantheon;" so that the line looks like "OnlyShowIn=Unity;GNOME;Pantheon;" For missing time, the information on https://bugs.launchpad.net/elementaryos/+bug/1356698 could help: probably this is a ...

There are three reasons, history, purpose and philosophy. Debian is much older than Ubuntu, and is hesitant to break things that work, particularly when the replacements require user intervention. Ubuntu is newer and had no install base when they developed their solution. Ubuntu is designed to be easy to use, Debian is designed to be powerful. My favorite ...

I believe you are looking for I believe you are looking for Iso booting with grub2 or the equivalent for your bootloader. Gummiboot seems to support it as well for instance. Be warned however that the partition on which the iso is placed has to be wisely chosen, since you may not be able to use that same partition in your new installation. The ubuntu ...

While dual booting is a useful concept to allow you to use both Windows and Linux on the same machine, the benefits of dual booting Linux are more subtle. The boot process in Linux typically involves using a boot loader to load a kernel and ram disk which eventually mounts the root file system and lets you do things. Different distros have different kernels, ...

This scheme is certainly workable. You are right, the best solution is to transform your current layout as little as it is possible. If you don't ask Arch Linux to install his Grub bootloader, you'll have to run grub-mkconfig -o /boot/grub/grub.cfg in Ubuntu (if you have os-prober installed, it will find your Arch installation and update all the config ...

I suggest you put a question into your Question so that it becomes clear what you're asking. If you're wanting to determine the authentication method, here are a couple of approaches. Boot your Windows system, connect, and then take a look to see what authentication method it has used. On Windows 8.1 right click the Network Icon (bottom right), open the ...

So I have seen the same question asked on 5 different stackexchange sites, and all the answers say to just remove the hotkey, which does work, but isn't the root of the problem (at least it wasn't for me). The real problem is that the windows super key is not mapped correctly, as is described here: i3 ignores mod4 (windows key) when in VNC session ...

According to the Nginx documentation, SIGQUIT will perform a "graceful shutdown" while SIGTERM will perform a "fast shutdown". At least as of version 1.8.0, Nginx will leave stale UNIX domain sockets when it is stopped using the SIGQUIT signal. However, the UNIX domain sockets are properly removed when using the SIGTERM signal. The Nginx service script ...

After some time spent talking to the poster in the U&L chat room, it because obvious this was a Python problem, specifically an encoding problem.

Based on this response, I have done the following and it works. sudo nano /etc/gdm/gdm.conf In this file, I added the following line. FirstVT=7 In /etc/gdm/gdm.conf you can set what the 1st terminal should be the graphical interface. FirstVT=7 will make GDM check tty7 first (by the way: this could mean it ends up on tty8, tty9 if these are ...

Doing what py4on suggested does simply shorten the list of available languages (to the extend of having one single element: en), but does not automate the language selection. It was probably working on older versions of Ubuntu but the requirement is for the Ubuntu Server 14.04. In order to avoid this intervention at the language selection menu, the option ...

When the linker generates an executable (or another shared library), it searches for libraries requested using -l by prefixing lib and suffixing .so to the name. For example, if you ask for -lcrypto then it searches for libcrypto.so. Once the library has been found, the linker reads a piece of metadata from the library called its soname. The soname then ...

checkinstall needs sudo, because by default it actually performs the installation as well. This is due to the default /etc/checkinstallrc, which contains: # Install the package or just create it? INSTALL=1 To prevent the installation, and just create the package, do: checkinstall --install=no

So /var/www/public_html is actually as Windows folder, but /var/www/data is not?  You're trying to create a symbolic link from a Windows directory into a Ubuntu directory in a virtual machine.  There's no way that Windows can support an object like that.

When the kernel detects a new device, it runs the program modprobe and passes it a name that identifies the device. Most devices are identified through registered numbers for a vendor and model, e.g. PCI or USB identifiers. The modprobe program consults the module alias table /lib/modules/VERSION/modules.alias to find the name of the file that contains the ...

Modules are loaded when the system boots via the Initial RAM Disk a.k.a the initrd. The Rationale Section states: Many Linux distributions ship a single, generic Linux kernel image – one that the distribution's developers create specifically to boot on a wide variety of hardware. The device drivers for this generic kernel image are included as ...

It's not a general shell issue. A program you fire up (such as screen) reads its .rc-file when you start it—it doesn't try to determine if that file was created before or after you logged in. (And it couldn't; Linux has no reasonable way to check a file's creation time.) So that's not what's going on. Instead, it's something about that login session. It ...
