I had a a problem wit python 3.9 update
python: error while loading shared libraries: libpython3.8.so.1.0: cannot open shared object file: No such file or directory

Was “solved” linking the library from python 3.9
sudo ln -s /usr/lib/libpython3.9.so.1.0 /usr/lib/libpython3.8.so.1.0

Now works fine

❯ python -V
Python 3.9.1

No it’s not:

  • Switch to a console using Ctrl+Alt+F2

  • Log in as Admin user

  • Execute:

    sudo -s
    

    to become root

  • execute:

    diff --side-by-side /root/.zshrc.pacnew /root/.zshrc 
    
  • See if you need to copy-paste anything from /root/.zshrc.pacnew to /root/.zshrc.

  • If you don’t, just delete the .pacnew

  • if yes, please use your favourite CLI editor to incorporate the changes (nano, vi, emacs) Not Kate / Gedit / Atom / …

  • exit the root prompt ASAP as that’s the way to totally fùçk up seriously mess up your system.

A post was split to a new topic: Errors after update

Alright!

For all of you having black screen with AMD GPU with kernel 5.10


For GRUB:

  1. Open a terminal/TTY (alt+f2)
  2. Enter sudo nano /etc/default/grub
  3. Find the line: GRUB_CMDLINE_LINUX_DEFAULT="
  4. Add amdgpu.dc=0
  5. Save, then run sudo update-grub

For systemd-boot:

  1. Open a terminal/TTY (alt+f2)
  2. Enter sudo nano /boot/loader/entries/manjarolinux5.10.conf
  3. Add amdgpu.dc=0 to the end of the line options
  4. Save & reboot!

Hope this helps!
It is a bug in the latest AMD drivers…

Try again from a command line:

pamac upgrade

:+1:

Kernel 4.14, Xfce.
All fine: I had to do the usual system maintenances to check pac files and rebuild AUR packages; however, now in the journal logs, I see a new warning:
systemd[1004]: -.slice: Failed to migrate controller cgroups from /user.slice/user-1000.slice/user@1000.service, ignoring: Permission denied

Which seems to need this Grub parameter:
systemd.unified_cgroup_hierarchy=true
https://bbs.archlinux.org/viewtopic.php?id=261330

I will try and report back.
EDIT:
Yes: I needed to add systemd.unified_cgroup_hierarchy=true to grub to get rid of such error, but I’d like to know if it is ok.

Oh, thanks, but already updated… Wouldn’t even be able to run this, as pamac partially uninstalled itself for some reasons…

But sweet, all issues are fixed for me, now!!

Your theme is not compatible any more… Try another one…

:sob:

Ah, ok, thanks.

Do I get that corrrectly: Commenting out that grub line would prevent the warning to appear, but also prevent the usage of systemd-fsck?
So I can ignore this warning?

5.9 is EOL. Try 5.4 LTS (Long Term Support) Instead…

:sob:

Works…
Thank You…

I am happy to say everything works sweetly!! :partying_face:

The AMD GPU driver did not work, but with the fabulous help of @The_Quantum_Alpha, it is up and running!! :blush:

Thank you for Manjaro updates :hugs:

Wish a sweet sweet day! :grinning:

Do NOT do that. Whatever AUR package you ran that produced that error needs to be rebuilt.

Hi,

I had a small issue, the bpython interpreter got uninstalled for some reasons, so I tried to reinstall it, there was a few file conflicts but removing them was enough to solve it, everything is back to normal now.

Also there is something I find weird :
I had nvidia 450 driver installed so far, and when I run mhwd -l, it’s not listed anymore in the avaiable drivers, which means it should have been uninstalled, but nvidia-smi tells me that 450 is still here, I also did a short test with pytorch and everything works fine, any explanation ?

@Fabby Thanks, that helps me :slight_smile:

and especially note:

(I’m in the same situation here: need to go to Nouveau as I’m on a GTX 1070 and that should be supported now but too tired to try now)

:bed: :zzz:
