Unable to find cores

[willysr]

Hi,

I'm using Slackware-current (development snapshot) and running latest conty and it used to work fine but now when i tried to run lutris, it always gives me this message

2021-07-27 18:15:05,409: Magic not available. Unable to automatically find game executables. Please install python-magic
2021-07-27 18:15:05,602: No cores found

i tried to run -u or -U but at the end of the process i get

This doesn't look like a squashfs image.
Mounting the squashfs image failed!

Hi,

2021-07-27 18:15:05,409: Magic not available. Unable to automatically find game executables. Please install python-magic
2021-07-27 18:15:05,602: No cores found

These are not critical errors, i get them too, but Lutris works for me. Are there any other errors?

Also, could you please try this release and see if it fixes the issue? It includes the python-magic package, just in case.

[willysr]

ok python-magic warning is now gone, but the second warning about no cores found is still there and lutris bar is starting but no apps displayed.

[willysr]

steam works fine though here

[Kron4ek]

That's really odd. So "No cores found" is the only message it shows, nothing else is in the output? I suggest you to try to remove or rename Lutris's config directories so it would recreate them, maybe this will help.

mv ~/.local/share/lutris ~/.local/share/lutris_bak
mv ~/.config/lutris ~/.config/lutris_bak

[willysr]

Here's the result after running two commands above

Sorry, i don't know why it doesn't work for you, there are no critical errors in the output. I mean, i see the same messages when i run Lutris myself, but it works for me anyway.

Do you remember when it got broken? Was it after updating to a new Conty release or maybe you changed something in your system (that should not affect the container, but still)?

[willysr]

i'm running a development cycle of Slackware-current so things gets changed, but i assume it should be the same as conty is based on Archlinux. I didn't change much, except following the changes in Slackware-Current. Here's the ChangeLog if if helps you find anything that might give a clue: http://www.slackware.com/changelog/current.php?cpu=x86_64

Yes, in fact, systemd-wide changes should not affect the container at all, except maybe for some rare cases.

The Lutris package has been updated (from 0.5.8.3 to 0.5.8.4) in the 1.14.1 conty release, so you could try the 1.14 release, which includes the previous Lutris version.

Another thing that you could try is to enable sandbox:

SANDBOX=1 ./conty_lite.sh lutris

And to switch to the classic i965 driver if you are using a modern enough Intel integrated GPU.

MESA_LOADER_DRIVER_OVERRIDE=i965 ./conty_lite.sh lutris

[Kron4ek]

And you can try to disable network access for the container:

DISABLE_NET=1 ./conty_lite.sh lutris

I know Lutris needs internet access to download runners, scripts and other things, but still i suggest to disable it for testing purposes.

[willysr]

Here's what i got after trying with SANDBOX=1

[willysr]

DISABLE_NET=1 works but i got this message on console

[Kron4ek]

And without DISABLE_NET you get an infinite "Lutris is starting" window, right?

[willysr]

yes

[Kron4ek]

Ok, i guess i know why this happens. The fact that disabling network helps likely means that Lutris is either trying to resolve some url or urls infinitely (or very long) or is trying to download something and the download speed is very slow.

Try to wait some time, maybe it will move on eventually. And probably some network monitor might help to find out to which urls Lutris tries to connect.

[willysr]

it should be this one https://api.github.com/repos/lutris/dxvk/releases but it's accessible via browser

[Kron4ek]

Try to download it manually.

cd ~/.local/share/lutris/runtime/dxvk
wget -O dxvk_versions.json "https://api.github.com/repos/lutris/dxvk/releases"

However, the releases json is not the only thing Lutris downloads from this github repo, it also downloads latest dxvk release.

[willysr]

tried it and no luck here....

[willysr]

i ran into this page: https://forums.lutris.net/t/solved-lutris-wont-start-launch/11653
tried running the command that worked for most people there and it still doesn't work for me

[willysr]

Do you have this message on your system?

because i checked on my .local/share/lutris/runtime directory, all those files are locally available

[Kron4ek]

I have these messages only on the first Lutris launch after removing ~/.config/lutris and ~/.locale/share/lutris, next time i launch it there are no these messages, unless i remove or rename the config directories again.

And yes, i have the "Loading of DXVK versions failed, defaulting to locally available versions" message too, but, again, only on the first launch.

[Kron4ek]

Here is how my Lutris output looks on the first launch, and here is how it looks on next launches.

[willysr]

i leave it overnight and now it's working again. I guess you are right, it tried to download things in the process and it took time
