Unresolved dependency after yum update crash (broken ssh connection)

Question

Today I was updating one of production server (one of many to test updates and then update the rest of computers).

Soon after run yum update ssh connection was broken :/ . After login once again using screen sesion this time I run yum-complete-transaction but it has problems so I run it with --skip-broken parameter. That worked fine for unfinished transaction but problem with perl dependency stays. I tried to reinstall perl package but it gives me an error :


Loaded plugins: langpacks, presto, refresh-packagekit
Installed package 4: perl-5.14.2-201.fc16.x86_64 (with updates) is not available.
Error: There is nothing to be done

This error I get trying to yum update:

 You could try using - skip-broken to work around the problem
** Found 6 pre-existing problems of the RPM database. The result of the command "yum check":

(this is translated to english from my native language)

How to deal with it? (next time I will use screen for update system)

My system is Fedora 16 with 3.2.3-2.fc16.x86_64 kernel.

Quickly run a yum clean all, followed by an RPM database check - rpm --rebuilddb - Then try again.

And you're right... Definitely use screen the next time you're running a critical or important system processes in the foreground on a remote session.

No that didn't help. Still the same error. – B14D3 Nov 07 '12 at 12:48
Can you run a `yum repolist`? – ewwhite Nov 07 '12 at 13:18
Yes I can :). Thx for your fast reaction :) – B14D3 Nov 07 '12 at 13:30

I manage to resolve deps by removing perl-libs, perl-threads, perl-Pod-Escapes. Removing this apps was easy (no dependency). After that yum update and everything is ok even removed apps was updated (there was a problem with some kind of duplicates I think).

Lesson for me use screen :)
