  • I'm trying "yum install ncdu", and getting "No package ncdu available." (See unix.stackexchange.com/questions/3961/…). What now? – ripper234 Nov 12 '10 at 10:25
  • @ripper234 Not all distros provide ncdu – N J Nov 12 '10 at 10:33
  • So, what are my options then? Do I have to download the source and compile? – ripper234 Nov 12 '10 at 11:18
  • Suse uses yast not yum – xenoterracide Nov 12 '10 at 13:26
  • @ripper234 ... I don't know what that is but I'll bet it's in an external repo, try asking a second question on here "how can I install ncdu on Red Hat" and ask if it's available in any repo's in the text. – xenoterracide Nov 12 '10 at 13:27

For Debian/Ubuntu

aptitude install firefox

For Fedora i think it is 

yum install firefox

[note] Run these as root.

If you are using Red Hat Enterprise Linux, it happens that the package you are looking for is in EPEL, so you can install that:

sudo rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm

and then you can yum install ncdu.

If you are using ancient Red Hat Linux, the answer is for the love of all that is holy, time to upgrade to Fedora.

  • Upgrading is not always possible. Have some compassion :) – spemble May 30 '18 at 13:30
  • @spemble Well, sure, but even at the time I wrote that, Red Hat Linux 9 (the last release) had been out of support for almost seven years. Now, it's been fourteen. The number of unpatched local and remote exploits is horrifying to consider. – mattdm May 30 '18 at 13:41
  • My job has me working on RHEL 4.6 and SCO Unix v5. You can imagine the frustration. Just saying. – spemble Jun 2 '18 at 17:47

For RHEL distrib for remote installation and repositories installation to yum OK, Here we have some additional details :

RHEL 2,3 and 4 :

    up2date -i pkg-name

RHEL5,6 :

    yum install pkg-name

RHEL7 yum group install group-pkg-name

RHEL 5,6 & 7: 

    yum groupinstall group-pkg-name

RHEL 2,3,4 : up2date "@group-pkg-name"

If you have to install any rpm package local, avoid to use :

    rpm -ivh http://...

and prefer use :

    yum localinstall http://...

or

Legacy distribution RHEL 2,3,4 :

    up2date -k pkg-name

Note : maybe http://... if not wget -0 http://... after up2date -k pkg-name

All of this to keep your metainformation yum (or up2date) ok and sync with rpm.
