Today I was trying to install Debian Jessie (8.6 20160917 15:03), using netinstall ISO, Live CD ISO (on usb device) and network boot install.

But every time, after create all partitions the installer ask for a cd rom on /media/cdrom and get stuck there.

Any hint on this problem? I don't know wath to do.


Using a live cd install, I follow this steps:

  • Click on Application Launcher
  • Execute "Install Debian Jessie"
  • Select a Language: English
  • Select your location: Other - South America - Chile
  • Configure Locales: United States - en_US.UTF-8
  • Configure the keymap: Latin America
  • Detect network hardware - Load firmware for Realtek device - No (I tried with the realtek firmware on an USB device but it not detect it)
  • Configure the network: eth0 (same result with wlan0)
  • Set the machine and domain name
  • Set root password
  • Set user and password
  • Configure the clock: Santiago
  • Partition Schema:
    • sda5 ext2 /boot
    • sda6 LVM
      • ext4 /home
      • ext4 swap
      • ext4 /

At this point I got this message:

/media/cdrom/: Please insert the disc labeled 'Debian GNU/Linux 8 Jessie - Official Snapshot amd64 LIVE/INSTALL Binary 20160917-15:03' in the drive '/media/cdrom' and press enter.

UPDATE I just skip the internet connection settings and install the defaults "CD-ROM" packages. Then update the sources.list file with some jessie repositories and did an update

sudo apt-get update sudo apt-get upgrade

  • The installation will ask you if you want to add any mirrors. Say no and it will continue only with the so called base system. – Willian Paixao Nov 11 '16 at 19:18
  • Which did you use to install? The Netinstall ISO or the Live CD ISO? Or are you saying you tried three methods and got the same error? – roaima Nov 11 '16 at 19:18
  • @roaima Yes, I tried three diferents methods and got the same error. I will edit including all steps using a LIVE CD Instalation (on a USB device) – Jose Truyol Nov 11 '16 at 19:23

I'm going to assume it is asking for a different CD/DVD to the single one you've got for the installation.

This is because it cannot find the packages you've requested on the CD/DVD and it needs to get them online. But presumably you haven't provided a mirror either so it's got no recourse except to assume it's an offline installation and you have a collection of CDs/DVDs ready to feed it.

Solution: either provide a mirror or don't ask for packages that aren't on the single installation disk.

If you're running from the NetInstall ISO, then there's only enough for a minimal system on the image. Everything else has to come from the network (hence the name).

  • I did a mirror selection. This is no the first time that I install debian, but today I downloaded the latest Debian Image. So, on netinstall Debian will download everything from internet (I assume) – Jose Truyol Nov 11 '16 at 19:30

You can mount your removable media manually as describe here:

D.3.4.2. Mount Partitions

Current Debian systems have mountpoints for removable media under /media, but keep compatibility symlinks in /. Create these as as needed, for example:

Press Alt + F2 then type:

 cd /media
 mkdir cdrom0
 ln -s cdrom0 cdrom
 cd /
ln -s media/cdrom

Then press Alt + F1


Just unplug your usb, wait a few moments, plug it back into the same port and the install should continue after pressing 'next'.
