[SOLVED] Strange things happening with pacman package manager

MTK358 · 02-10-2010, 12:00 PM

I decided to update using "pacman -Syu", and it said:

Code:

$ sudo pacman -Syu
:: Synchronizing package databases...
 core is up to date
 extra is up to date
 community is up to date
:: Starting full system upgrade...
:: Replace kdelibs-experimental with extra/kdelibs? [Y/n] 
resolving dependencies...
looking for inter-conflicts...
error: failed to prepare transaction (could not satisfy dependencies)
:: kdelibs: requires phonon

I didn't know what to do, si I ran "pacman -S kdelibs" (BTW, phonon was not one of its dependencies). Then I tried to update again. Same thing! So I decided to run "pacman -Rns kdelibs" to get back to my previous state. But it says that some programs I have depend on it! How it that supposed to be if those programs worked before? Anyway, I decided to install phonon. But it said that it conflicts with Qt and asked me if I want to remove Qt!

What should I do?

I don't know if this is relevant, but I sometimes select a different mirror, re-sync, and then run pacman -S again. I assume that the mirrors are simply not always staying synchronized.

Also, there's a new utility for selecting the best mirrors to use. I've not yet mustered the neurons to tackle this.

Before I read the announcement, I solved the problem with simply removing qt and then upgrading.

Code:

pacman -Rd qt
pacman -Syu

If you're talking about "rankmirrors", I did that right after installing Arch.

Now you're making me feel inferior.....

Do you have more than one mirror enabled? When I read the instructions, it sounded like this was possible. (I have always assumed that Arch could only use one mirror at a time)

That seems to work, and I see that Qt is included in the updates.

Will I have to do this every time I update?

AFAIK if you have more than one mirror selected it chooses the first one on the list, if it fails it tries the second, etc.

No, you won't have to do that everytime you update. This was a special case involving a major upgrade. A couple times a year something big comes down the pipe and you have to pay extra attention to what's going on.

Yes, you are correct regarding the mirrors. It tried each in order. However, you can use either powerpill or bauerbill, which does allow you to use multiple mirrors (utilizing reflector to do so). All of those are in the AUR (actually I think reflector is in the community repo) or you can enable Xyne's (the author) repo.
