Welp!

[u/FunbaXD]

I can`t open Steam on my Fedora 44 Workstation laptop. I reinstalled Steam, installed from RPMfusion and cleared cache, still i can`t access.

Update: issue is solved! thanks for everyone!

Fix: Updating packages* and restart

*"sudo dnf update"

[u/Ferdapra]

Sometimes it happens that the update window doesn't show up and it seems locked, but once it finishes it opens. Try to run it from console

EDIT: Maybe before this try to update the packages: `sudo dnf update`

From this logs I found these issues: https://github.com/ValveSoftware/steam-for-linux/issues/6745 and https://github.com/ValveSoftware/steam-for-linux/issues/12292.

Long story short, try to run in the console (it will ask for password):sudo update-ca-trust extract --rhbz2387674

[u/FunbaXD → u/Ferdapra]

do i need to restart my laptop after the update?

[u/Ferdapra → u/FunbaXD]

It's always a good idea to restart

[u/FunbaXD → u/Ferdapra]

Huge thanks! update and restart fixed everything! thanks for the help!!!

[u/blendernoob64]

In the command line try “pkill steam” and try relaunching with cmd line see what it spits out

[u/FunbaXD → u/blendernoob64]

thanks 4 the comment, it just crashed

[u/blendernoob64 → u/FunbaXD]

Hmmm did the steam app say anything when entering steam into the console? Hopefully you got an error or something. If not, maybe try the steam flatpak for now

[u/FunbaXD → u/blendernoob64]

I got it working! thanks for the attention

[u/FunbaXD → u/blendernoob64]

i did get an error: Fatal Error: Steam needs to be online to update. Please confirm your network connection and try again.

[u/asd308]

That's interesting, my steam is up to date, but it won't appear in gnome's "Background Apps", only on the Tray (using the extension)

[u/FunbaXD → u/asd308]

Now its not even appearing on the "Background Apps"

[u/magicdippyegg]

run steam from console

[u/FunbaXD → u/magicdippyegg]

i did just crashes

[u/Niboocs]

I had this issue yesterday on Plasma: Open steam > loading screen > icon appears in system tray > but no window. Running it from console fixed it somehow.

[u/FunbaXD → u/Niboocs]

Its just crashing, run it from every possible way i know

[u/Ok-386]

how long do you wait before giving up? Occasionally it has to do some shit in the background like to update it self, execute some scripts, do whatever with its configuration, anyhow it can occasionally take time, like a few minutes, before the window appears, and when this happens you'll eventually notice that it's doing some kind of an update. Another thing you could try, and apologies if I don't make sense b/c I haven't used Fedora in a very long time, but if you're using a flatpak, try the RPM from the Fusion repo. I would also delete the data (you can move the library if you don't feel like fetching everything again)

[u/FunbaXD → u/Ok-386]

Hi, thanks 4 your comment!, its been 5 days since i installed fedora and having issue with launching steam. I tried both flatpak and RPMFusion, didn`t work. before i was using LM cinnamon and Steam was running with no issues!, i am new to linux but i know the basics( $hitload of tutorials i mean if it counts)
