PHP 8.0 and PHP 7 legacy packages are available
PHP 8.0 and PHP 7 legacy packages are available
2021-01-28 - Pierre Schmitz
The php package has been updated to version 8.0. Please refer to the upstream migration guide. As some applications are not compatible with PHP 8 yet we provide a php7 package which can be installed alongside version 8. Packages that depend on PHP reflect this update and will require php7 if needed. You might need to update your configuration accordingly. PHP 7 binaries and configuration have the “7” suffix:
Note that support for php7 will be limited and likely be dropped in about a year depending on how soon the majority of applications will be compatible with version 8.
Google has announced that they are going to block everything but Chrome from accessing certain Google features (like Chrome sync) starting on March 15. This decision by Google is going to affect Arch’s chromium package a bit earlier, on March 2, when Chromium 89 gets released.
We know for sure that data syncing will stop working (passwords, bookmarks, etc.). Other features such as geolocation or enhanced spell check might continue to function for a bit longer. Extensions integrating with Google Drive might misbehave and LibreOffice will lose access to documents stored there.
Other distros such as openSUSE and Fedora have already removed the soon-to-be-limited API keys from their Chromium 88 packages. Fedora’s advisory provides a great deal of perspective on this and I also found this Hackaday post to be quite informative.
We recommend to switch over to Nouveau drivers if your card is mentioned here and the feature you need is not in red TO DOhere for your particular card.
If you however still need proprietary drivers, you may want to execute the following to ensure all parts of the nVidia drivers get installed properly:
sudo mhwd -a pci nonfree 0300

For AMD GPU users having a black screen with kernel 5.10
Please click the ► at the beginning of this line to view more info
Due to a bug in the AMD drivers, please try the following first:
For GRUB:
Open a terminal or a TTY
Open /etc/default/grub in your favourite CLI editor (nano vi, emacs`)
Find the line: GRUB_CMDLINE_LINUX_DEFAULT="
Add amdgpu.dc=0
Save
Execute sudo update-grub and reboot
For systemd-boot:
Open a terminal or a TTY
Open /boot/loader/entries/manjarolinux5.10.conf in your favourite CLI editor (nano vi, emacs`)
Add amdgpu.dc=0 to the end of the line options
Save & reboot
For rEFInd:
Open a terminal or a TTY
Open /boot/refind_linux.conf in your favourite CLI editor (nano vi, emacs`)
Find the line: "Boot using default options" "root=
Add amdgpu.dc=0
Save & reboot
Possible 2 Min delay on shutdown with Gnome
Please click the ► at the beginning of this line to view more info
If you got the problem with shutdown delay (about 2min) on Gnome, here is a workaround:
Edit /usr/lib/systemd/user/gnome-session-restart-dbus.service in your favourite editor as root and add Slice=-.slice as a line all by itself like this:
You get [PKGNAME] warning: directory permissions differ on [Directory name]
followed by:
Filesystem: NNN package MMM
Please click the ► at the beginning of this line to view this solution
The solution:
sudo chmod MMM DirectoryName
Where obviously MMM is the second number you see (the correct one)
The explanation:
Your package expects the security permissions to be MMM but your system is set to NNN. This is just a warning (today) but to ensure you remain up-to-date with the latest and greatest security rules it’s advised to execute the above command.
Systemd error message: .slice: Failed to migrate controller cgroups
If you have a similar error message like this:
systemd[1004]: -.slice: Failed to migrate controller cgroups from /user.slice/user-1000.slice/user@1000.service, ignoring: Permission denied
… you may need to add this Grub parameter to your /etc/default/grub file in line GRUB_CMDLINE_LINUX_DEFAULT: systemd.unified_cgroup_hierarchy=true. To update your grub menu, call: sudo update-grub. For more information on that issue, see also Arch Forum.
Python 3.9 Requires Rebuilds
Instructions for quickly and easily rebuilding affected AUR packages:
# Install yay
sudo pacman -S --needed --noconfirm yay
# Rebuild AUR python packages
yay -S --noconfirm $(pacman -Qqo "/usr/lib/python3.8/site-packages")
The libtraceevent package prior to version 5.9-1 was missing a soname link. This has been fixed in 5.9-1, so the upgrade will need to overwrite the untracked files created by ldconfig. If you get any of these errors
libtraceevent: /usr/lib/libtraceevent.so.1 exists in filesystem
PAM and PAMBASE got updated, which might prevent you from login
Due to updates from pambase and pam you might take care about any .pacnew files in /etc/pam.d as for example pam_tally, pam_tally2 and pam_cracklib got deprecated. Read in the ArchWiki about managing those files.
Typical issue:
For recovery, it is enough to boot with kernel option “systemd.unit=rescue.target”, then proceed into /etc/pam.d and merge “system-auth” and “system-auth.pacnew”
System takes a long time to boot
If you’ve got errors like Failed to start Network Manager Wait Online. you can try removing systemd from passwd and group in /etc/nsswitch.conf as described here Update: If you can see the line dbus-daemon[1453]: [system] Connection has not authenticated soon enough, closing it (auth_timeout=30000ms, elapsed: 45146ms)
in in your dbus log ( journalctl -b -u dbus ), the new/better workaround is to switch cups from service to socket as described here: systemctl disable cups.service systemctl enable cups.socket
I think I’ve some font problems
With the update of fontconfig some major rules how fonts get applied changed. Make sure that your system has ttf-dejavu installed. A more in depth explanation can be found here.
Gnome-shell-extension-pop-shell is currently incompatible with wayland
… and causes the system to freeze when the first window is tiled and can render it unbootable. Solution is a hard reset and disabling either pop shell or wayland. If the system becomes unbootable, use a live USB to edit /etc/gdm/custom.conf to disable wayland and reboot.

Running cinnamon and update has broken the desktop. I can still launch things from the panel but I can’t do anything at all on the desktop. Right click, left click , can’t do anything. Also nemo won’t respond either so guessing it’s tied in together
With the --overwrite parameter, you can define which files are allowed to be overwritten with the update: pacman -Su --overwrite "/usr/share/de/man1/*.gz"
The problem with relying on pacman -Qdt output is that it ALSO lists some packages installed when you built something from AUR. For example, go package was likely pulled for building some app written in Go language. So if you remove it, next time when there’s an update to your AUR app, it will be pulled and installed again. So if you have some apps which are usually built from source, it might be a better approach to leave make dependencies installed and mark them explicitly installed so they won’t be listed when querying with -Qdt flags. That’s usually are boost, rust and go. To mark them, issue sudo pacman -D --asexplicit <packagename>
I’ve figured out the issue with nemo and the latest update but have no idea to fix it. No matter what theme I run I get the following gtk error
Current gtk theme is not known to have nemo support (CBlack) - checking…
and it just hangs there until I have to fc nemo. I’ve tried every theme there is and its the same issue, I have to select a theme so nemo and the desktop are unusable
Edit
Seems megasync was the issue, removing megasync and nemo-megasync plugin fixed it
can someone explain briefly why we insist on having the nvidia-uvm module removed from Nvidia driver 390?
From PKGBUILD:
# Fix compile problem with 5.10
# FATAL: modpost: GPL-incompatible module nvidia-uvm.ko uses GPL-only symbol 'radix_tree_preloads'
msg2 "PATCH: disable-module-nvidia-uvm"
patch -p1 -i "$srcdir"/disable-module-nvidia-uvm.patch
If I understand the comment correctly, there was formerly a compile problem due to a GPL issue. As I cannot reproduce this problem here anymore (driver compiles well with nvidia-uvm included), I am just wondering why it is still necessary to have the nvidia-uvm module removed from the linux510-nvidia390xx package.
Is it safe to do? Won’t it change package ownership of those files which could cause similar issue in the future? I’m just asking, because I don’t understand how this package ownership works.
@philm, what is the advised solution? Move to .old, overwrite or any will do? Or maybe wait for the upstream fix?
I’m using video-hybrid-amd-nvidia-prime, and since this driver update (460), I can’t run any game or blender. I’ve tried changing the kernel to LTS, fully uninstalled and installed steam, deleted all installed games (but later found that other 3D applications were affected). The AMD (Vega) GPU runs flawlessly.
