ansible-core >= 2.15.3-1 update may require manual intervention

2023-08-19 – Robin Candau

As of ansible-core 2.15.3, upstream moved documentation and examples to a separate dedicated repository (see the related changelogs).
This means that, starting from version 2.15.3 the ansible-core package will stop shipping documentation and a default configuration example under /etc/ansible/ansible.cfg.

Regarding the documentation, it is available online: https://docs.ansible.com/
As for the configuration file, as explained in the wiki, a base config can be generated with the following command:

ansible-config init --disabled > ansible.cfg

After updating from ansible-core <= 2.15.2-1 to >= 2.15.3-1, everyone using a custom global Ansible configuration file stored under /etc/ansible/ansible.cfg will have their configuration saved as a pacsave file.
To restore it, run the following command:

mv /etc/ansible/ansible.cfg.pacsave /etc/ansible/ansible.cfg

Possible glibc 2.38 posix_memalign regression

There seems a performance regression of posix_memalign in Glibc-2.38. More info here: 30723 – Repeated posix_memalign calls produce long free lists, high fragmentation

Workarounds:

You can try another malloc like mimalloc or jemalloc as workaround. Install mimalloc and start mpv with:

LD_PRELOAD=/usr/lib/libmimalloc.so mpv

LD_PRELOAD=/usr/lib/libjemalloc.so mpv

For folks that dont want to change things too much … an apparent workaround is to set a lowish cache size:

mkdir -p ~/.config/mpv && printf 'ndemuxer-max-bytes=50MiBndemuxer-max-back-bytes=25MiBn' | tee -a ~/.config/mpv/mpv.conf

budgie-desktop >= 10.7.2-6 update requires manual intervention

When upgrading from budgie-desktop 10.7.2-5 to 10.7.2-6, the package mutter43 must be replaced with magpie-wm, which currently depends on mutter. As mutter43 conflicts with mutter, manual intervention is required to complete the upgrade.

First remove mutter43, then immediately perform the upgrade. Do not relog or reboot between these steps.

pacman -Rdd mutter43
pacman -Syu

Steam crashes on startup with lib32-libgudev installed

The latest lib32-libgudev update does not cooperate with the version of the same package provided by steam, and steam seems to attempt making calls to both leading to the crash.

Details: bug report, arch task, arch forum thread.

Workaround #1 (causes steam to avoid making any calls to lib32-libgudev by using a different library altogether)
- sudo pacman -S lib32-libnm
Workaround #2 (forces steam and any other application to always use the new lib32-libgudev)
- sudo pacman -S lib32-libudev0-shim
Workaround #3 (use steam-native-runtime, which doesn’t have the issue)
- sudo pacman -S steam-native-runtime

TeX Live package reorganization

2023-06-18 – Antonio Rojas

Starting from version 2023.66594-9, TeX Live packages have been reorganized to mirror upstream collections. Even though the new texlive-basic replaces the old texlive-core, many of the texlive-core contents (including language specific files) are now split between different packages. To find out which Arch package contains a specific CTAN package, you can use the tlmgr utility, eg.
$ tlmgr info euler | grep collection
collection:  collection-latexrecommended
which means the euler CTAN package is contained in texlive-latexrecommended. You may also use pacman -F to query for specific files.

A new metapackage texlive-meta is available to install all subpackages (except for language specific ones), and the new texlive-doc package provides the full documentation for offline use.

The “community” repository has been merged into “extra” and is now empty

The [community] repository has been merged into [extra] and is now empty. It may take a bit of time for mirrors to catch up.

Update your system and merge the pacman pacnew /etc/pacman.conf.pacnew file.

sudo pacman -Syu "pacman>=6.0.2-11"

OpenBLAS >= 0.3.23-2 update requires manual intervention

2023-06-14 – Felix Yan

The openblas package prior to version 0.3.23-2 doesn’t ship optimized LAPACK routine and CBLAS/LAPACKE interfaces for compatibility. This decision has been reverted now, and the ability to choose a different default system BLAS/LAPACK implementation while keeping openblas installed is now provided to allow future co-installation of BLIS, ATLAS, etc.

The default BLAS implementation will be used for most packages like NumPy or R. Please install blas-openblas and blas64-openblas to make OpenBLAS the default BLAS implementation, just like the old behavior.

Unfortunately you will get errors on updating if you currently have OpenBLAS installed as the default BLAS implementation:
error: failed to prepare transaction (could not satisfy dependencies)
:: installing openblas (0.3.23-2) breaks dependency 'blas' required by cblas
:: installing openblas (0.3.23-2) breaks dependency 'blas' required by lapack
Please append your preferred default BLAS implementation to the regular -Syu command line to get around it. For example:
sudo pacman -Syu blas-openblas
or
sudo pacman -Syu blas
