Mechanical HDDs may not spin-down properly on shutdown
There might be a regression introduced with 6.6.0-rc4 which got also backported to 6.1.59 and 6.5.8 Kernels. There is a discussion with the author of the offending patch ongoing here.
ZFS package changes
ZFS extramodules; i.e., linuxXX-zfs
, have been dropped from the repos. There have been recent difficulties building them and no one on the Manjaro Team uses ZFS.
Please install zfs-dkms
instead. You will to need to manually remove the old 2.1.13 extramodule package(s) first to install the new 2.2.0 packages; i.e., with linux61
:
sudo pacman -R linux61-zfs && sudo pacman -Syu zfs-dkms

GNOME Extensions that target older GNOME versions will not work in GNOME 45
It is recommended to remove all third-party extensions before updating, then install the compatible versions after updating and rebooting. All Most extensions in the Manjaro repos are already updated.

glibc-locales update requires manual intervention
If you had the old glibc-locales
package from the extra repo installed, the update to the new core package will need manual intervention:
sudo pacman -Syu glibc-locales --overwrite /usr/lib/locale/*/*

Changes to default password hashing algorithm and umask settings
2023-09-22 – David Runge
With shadow >=
4.14.0
, Arch Linux’s default password hashing algorithm changed from SHA512 to yescrypt [1].Furthermore, the
umask
[2] settings are now configured in/etc/login.defs
instead of/etc/profile
.This should not require any manual intervention.
Reasons for Yescrypt
The password-based key derivation function (KDF) and password hashing scheme yescrypt has been chosen due to its adoption (readily available in libxcrypt, which is used by pam [3]) and its stronger resilience towards password cracking attempts over SHA512.
Although the winner of the Password Hashing Competition [4] has been argon2, this even more resilient algorithm is not yet available in libxcrypt [5][6].
Configuring yescrypt
The
YESCRYPT_COST_FACTOR
setting in/etc/login.defs
is currently without effect, until pam implements reading its value [7]. If aYESCRYPT_COST_FACTOR
higher (or lower) than the default (5
) is needed, it can be set using therounds
option of thepam_unix
[8] module (i.e. in/etc/pam.d/system-auth
).General list of changes
- yescrypt is used as default password hashing algorithm, instead of SHA512
- pam honors the chosen
ENCRYPT_METHOD
in/etc/login.defs
and does not override the chosen method anymore- changes in the filesystem (>=
2023.09.18
) and pambase (>=20230918
) packages ensure, thatumask
is set centrally in/etc/login.defs
instead of/etc/profile

filesystem and bashrc-manjaro pacnews
With the filesystem
2023.09.03-1 and bashrc-manjaro
5.1.016-3 updates there may be pacnews for the following files if you have local modifications:
/etc/shells
/etc/bash.bashrc
This would be a good time to test @Ste74’s new manjaro-pacnew-checker
program. See Check and manage pacnew files for more info.

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 version2.15.3
theansible-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 apacsave
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 – Poor posix_memalign performance with long free lists
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
or
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
