How to check if package blocking update can be skipped

General system Newbie

On trying to update recently I received this warning:

error: failed to prepare transaction (could not satisfy dependencies)
:: installing libplacebo (5.229.1-2) breaks dependency ‘libplacebo.so=208-64’ required by mpv

As I’d prefer not to uninstall mpv how could I identify which other package uses this updated package? Presumably doing a “pacman -Rs libplacebo” would solve the problem but also might break mpv?

I could get by without it for the moment if that is what it takes to enable a complete update.

Repo packages should never block an update.

Can we see the full output from that update?

Also, can we see the contents of /etc/pacman.conf

The latest version of mpv requires libplacebo.so-229.64.

which is provided by libplacebo. So by right there shouldn’t be a problem.

Did you use ignore package for mpv?

Here is the file I created with cat added pacman.conf

Apologies for direct upload as I tried pastebinit but couldn’t get the right access.
I tried an upgrade on another Thinkpad I have with a recent installation of Endeavour OS and had mpv installed. There was no problem with the pacman update. Could it be the chaotic-aur repo causing the problem?

HoldPkg = pacman glibc ??

HoldPkg is packages that can’t be removed.

It is absolutely possible. However, first I would try resorting your mirrors and ensure you aren’t connected to a partially synced mirror.

As a side note, I am note sure what the impacts of holding back libgweather and libvterm01 are.

Oh okay …didn’t know that. :thinking:

You were right. Refreshing my mirror lists seems to have sorted the problem as update had not problem with libplacebo.

On a side note: I held back libgweather as well as grub-tools as I get a message that they are no longer in the AUR repo. So should I simply remove them?

grub-tools came from the eos repo and it has been removed.

It is up to you to decide to remove it or keep it installed. It provides some automation around grub. We removed the automation last year.

I would recommending removing libgweather if it is no longer in the repos or AUR.

Will do the removing. Many thanks for the rapid help on this great forum!
