RPM Cheatsheet

Common usage of yum/dnf to do nifty things.

FEDORA DUMP/IMPORT RPMS TO/FROM FILE

    dnf repoquery -a --installed --qf "%{name}" > rpms.txt
    
  • Import

    dnf -y install $(cat rpms.txt)
    
    or
    
    cat rpms.txt | xargs dnf -y install

    dnf search from_repo REPONAME |awk -F"\n" '{ RS=""; print $1 }'
    
  • EL6, EL7, Amazon Linux

    yumdb search from_repo REPONAME | awk -F"\n" '{ RS=""; print $1 }'
    

REMOVING ALL PACKAGES FROM A SINGLE REPOSITORY

RPM DEPENDENCY ERRORS

PACKAGE WENT AWOL

Not sure why this can occur, but it does. When an update or package install happens, you should pull in any new dependencies that arrive. Should this fail, here is how to fix it.

    sudo yum check
    sudo yum reinstall BROKEN_PACKAGE
    sudo yum check

Here is a sample output, forced by removing fuse-sshfs

  • The error noticed while doing another transaction

DUPE PACKAGES

If you run into an issue where you have one or more of this:

Error:  Multilib version problems found. This often means that the root
       cause is something else and multilib version checking is just
       pointing out that there is a problem. Eg.:

         1. You have an upgrade for libcurl which is missing some
            dependency that another package requires. Yum is trying to
            solve this by installing an older version of libcurl of the
            different architecture. If you exclude the bad architecture
            yum will tell you what the root cause is (which package
            requires what). You can try redoing the upgrade with
            --exclude libcurl.otherarch ... this should give you an error
            message showing the root cause of the problem.

         2. You have multiple architectures of libcurl installed, but
            yum can only see an upgrade for one of those architectures.
            If you don't want/need both architectures anymore then you
            can remove the one with the missing update and everything
            will work.

         3. You have duplicate versions of libcurl installed already.
            You can use "yum check" to get yum show these errors.

       ...you can also use --setopt=protected_multilib=false to remove
       this checking, however this is almost never the correct thing to
       do as something else is very likely to go wrong (often causing
       much more problems).

       Protected multilib versions: libcurl-7.29.0-59.el7_9.1.x86_64 != libcurl-7.29.0-57.el7_8.1.x86_64
Error: Protected multilib versions: nx-libs-3.5.99.25-2.el7.x86_64 != nx-libs-3.5.99.24-1.el7.x86_64

Not a good issue to have, but very fixable. The caveat is likely a bit on the manual side.

So first we want yum to do whatever it can automatically for us to clean up any dupes.

sudo package-cleanup --cleandupes

If that doesn't fully fix it (sometimes you get lucky and it actually will), you can try this variation of the command instead:

sudo package-cleanup --cleandupes --removenewestdupes

If that still isn't quite doing it, then its going to be manual from here on.

To fix the above example, we need to remove the RPM DB entry for the older package, and reinstall the new one to ensure everything went properly.

sudo rpm -e --justdb libcurl-7.29.0-57.el7_8.1
sudo yum reinstall libcurl
sudo rpm --rebuilddb

sudo rpm -e --justdb nx-libs-3.5.99.24-1.el7
sudo yum reinstall nx-libs
sudo rpm --rebuilddb

sudo yum check

You will need to do that for each broken element and conclude with the yum check to validate all is good. The output there will also remind you of anything that still needs repair.
