[SOLVED] libxml2 upgrade breaks dependencies

grobber · 2025-04-30 20:54:19

This is very recent, so I expect all it'll take is a bit of waiting, but I ask just in case I'm missing something I could do at my end. As of right now (2025-04-30; this is a very recent issue) attempts to update packages with 'pacman -Syu' fail with

error: failed to prepare transaction (could not satisfy dependencies)
:: installing libxml2 (2.14.2-2) breaks dependency 'libxml2.so=2-64' required by rest

Also:

$ sudo pacman -S libxml2

Rest isn't in the repos. It's up to you to rebuild foreign packages when they need to be.

grobber · 2025-04-30 21:09:42

I initially wrote the other packages seem to have the same dependency, but after removing rest (I do not recall installing it) the update went through fine.

I have very few AUR installs (always manual), and they are clearly named in a repos folder. rest is not among them and I have no idea how it got on here. In any event, its removal facilitated the update. Thank you, and I would be curious to learn if anyone else has run across this.

In any case, I will mark this 'solved'.

Those errors are when you're trying to do a partial update. Be grateful it stopped you, you would have broken a whole lot of things if it went through.

WorMzy · 2025-04-30 21:16:23

The Arch repo packages have already been rebuilt against the new library:
emacs: https://gitlab.archlinux.org/archlinux/ … ffcf01f5f0
libarchive: https://gitlab.archlinux.org/archlinux/ … 753e5dfed9
openconnect: https://gitlab.archlinux.org/archlinux/ … 8a7d6dc612

Either you are performing partial updates, or you're using an out-of-sync mirror.

Mod note: Moving to AUR Issues.

grobber · 2025-04-30 21:18:38

Thank you all; simply removing rest did it (please see my edited response above). Marking this 'solved'.

Had the same problem re 'rest', but have no idea where it is or how to remove it (not found by searching for installed packages). Thanks for help.
Later added: I entered "sudo pacman -R rest", and voila, "rest" was found - and deleted. The update then went like a charm. Thanks to those who helped with this one.

I had the same problem which is weird. I have my aur packages in a seperate repo but `rest` was listed as a local package and I couldn't see what depended on it. I'm glad the problem was resolved by simply removing it.

https://gitlab.gnome.org/GNOME/librest had at some point been installed as dependency for something but is no longer in the repos since 2+ years and no longer a dependency for anything.
(But still on my system, so thanks everyone for running into this so I won't )

I've the same error (https://bbs.archlinux.org/viewtopic.php?id=305310) and I'm not sure what to do ...

Can someone explain it me?

Before I uninstalled the "rest" package, I captured what "pacman -Qi rest" reported on it:

Command: pacman -Qi rest

This identifies "rest" as an Arch Linux package from Arch Linux Upstream. Apparently the package has been installed from the Arch Linux Repos as a dependency.

The package is relatively old (from Jan 2022). Nowadays, "pacman -Si rest" indeed results in:

Command: pacman -Si rest

error: package 'rest' was not found

There are multiple packages for "rest" present in my "/var/cache/pacman/pkg/" folder:

-rw-r--r-- 1 root root 89144 Aug 16  2017 /var/cache/pacman/pkg/rest-0.8.1-1-x86_64.pkg.tar.xz
-rw-r--r-- 1 root root 98471 May  7  2020 /var/cache/pacman/pkg/rest-0.8.1-2-x86_64.pkg.tar.zst
-rw-r--r-- 1 root root 98532 May  7  2020 /var/cache/pacman/pkg/rest-0.8.1-3-x86_64.pkg.tar.zst
-rw-r--r-- 1 root root 98368 Jan 17  2022 /var/cache/pacman/pkg/rest-0.8.1+r4+ge5ee6ef-1-x86_64.pkg.tar.zst
-rw-r--r-- 1 root root   141 Jan 17  2022 /var/cache/pacman/pkg/rest-0.8.1+r4+ge5ee6ef-1-x86_64.pkg.tar.zst.sig

So I conclude that the "rest" package has been dropped from the Arch Linux repos at some point, after the dependencies on it have been released.

I do not know a way to diagnose which other package pulled it in, though.

@friedrichr:

Did I understand it correct that I only have to remove the package 'rest'?

For me, yes.

If it is the same for you depends on whether you have or have not other packages installed which depend on "libxml2.so=2-64", and cannot be updated to use "libxml2.so=16-64" instead.

@grobber reported such for "emacs", "libarchive" and "openconnect". However, according to @WorMzy, these upstream packages already are updated in this respect, such that they depend on "libxml2.so=16-64" now. So, when you do "pacman -Syu", these packages should not yield the error discussed in this thread.

Does this sort the problem for you?
