old libraries

[jiml8]

I have a bunch of old libraries on this system. To this point, I have looked at lib64boost libs and lib64magick files.

WRT the libboost files, I won't delete the older versions because there could be compatibility problems with some programs that use older versions.

But how about image magick? Can I get rid of any libs that are not mageia7 libs?

I am sure there are others here where I am not sure what to do, but should I assume that if the installer left them behind they might be needed?

[jiml8]

Actually, as I look at this more, I think I have answered my own question.

It looks like that, wherever I forced an installation, the corresponding mga6 files were not removed. So, there's a few hundred of them, and I'm cleaning things up a bit by removing them.

There are often some orphaned library packages left behind after an upgrade, even if you haven't forced things. Generally it is safe to remove them with urpme. Just don't use the --auto option, and check that no mga7 packages will be removed as a consequence.

[doktor5000]

Also check https://bugs.mageia.org/show_bug.cgi?id=24895 - there used to be an entry for that in our errata, not sure why it's not there anymore. To summarize, there are quite a few packages with .mga6 suffix even on freshly installed mga7 systems.

A good start would be probably to go through the list provided by urpmq --not-available. That will show you all installed packages, that are not available from the currently configured repositories.

[jiml8]

Following your suggestions, I removed about 800 old libraries, ranging from mga2 to mga6.

After first being awed by the size of the list that urpmq --not available gave me, I pulled them up by generation (rpm -qa | grep mga3 for instance), then scripted the return into a script that removed each entry with urpme. I ran the script, and said "yes" or "no" every time it told me of dependencies that had to be removed. I said "no" if any mga7 package was a dependency.

Actually, it turns out that Maria DB for Mageia 7 is still using a Mageia 2 library on my system. I didn't expect that...

After removing all the old libs this way, running urpmq --not-available turned up a short list that mostly consisted of RPMs I have installed from other sources (brother printer drivers and such). There were a couple of mageia RPMs on the list; urpme on them made them go away when they didn't show any current dependencies.

This freed about 2G on my system partition.

To this point, I have not noticed any ill effects. I would imagine that it will be awhile before I do notice any ill effects, if there are any. And if there are, I still have all those libs in my backup archive; I can always go and get any lib I absolutely have to have.

I guess somewhere along the line an obsoletes has got missed. What library is it, and what is the output from 'rpm -q --provides' when passed that library name?

[jiml8]

This is what the script told me. I presume it is lib64pcre0-8.21-1.mga2.x86_64 because that one remains on the system.

Try installing lib64pcreposix1 and lib64pcrecpp0 (both at once). Hopefully that will evict the mga2 package and nothing else.

Yes, that did it.
