How to update rpm/yum database?

  • 772

For example I have installed mysql and httpd, but when I'm trying to 'yum update' then yum throws error that package is available but not installed. So, how can I update database of installed software?

This command have no effect:

rpm --rebuilddb
fedora

    If you've got a system with files from packages installed but an out-of-sync RPM database, you can use rpm -ivh --justdb somepackage.rpm to update the RPM database without actually installing anything. This is pretty messy, though, and really when you're in this state, it's time to start planning a reinstallation from scratch.

  2. You cannot update the rpmdb manually; it must be done via packages.

  3. How did you install httpd and mysql? It sounds like you did it through source, in which case you won't be able to update it using the repository.

  4. Try this

    yum clean all
yum search mysql

    Make sure your repos are loaded that have the mysql package you want

  5. There's definitely a language barrier issue here -- the rest of this post is going to assume you installed MySQL and Apache through yum, not from source, and then yum update broke on you.

    Check (and post) the rest of your yum output. If a package is available but cannot be installed, that usually means that one of its dependencies is faulty, which happens often if you have both the i386 and x86_64 versions of a package installed and you somehow end up with different versions. Once you get your dependency chain cleaned up, yum update should work normally.
