I figure the version of Celeste and the hardware I'm on will be important, so I'm on a Steam Deck running Bazzite and playing the Linux SDL3 beta version. I'll send the log file in a minute.
#Unable to install Everest

Ah. That makes sense.
All the other versions just randomly get unplayably choppy while I'm playing, so that's why I'm on that version specifically.
shut roost
there was some testing done to see what changes would everest need to support sdl3
@warm cipher
don't you have a fork
warm cipher
uhh i dont have binaries, i could make some real quick
shut roost
if they do, the sdl3 changes are more likely to blame
warm cipher
its also here https://github.com/Wartori54/Everest/releases/tag/sdl-upgrade-build1 so its easier to link
foggy jungle
Following the manual installation instructions, it doesn't seem to work and the game just doesn't start. Maybe I just didn't do it right?
shut roost
close steam (no, completely exit steam) and run celeste from the terminal
and see what it spits out
also wdym doesnt work
does the installation succeed
warm cipher
also id install that onto a completely clean sdl3 game build, i dont think upgrading will be magically handled properly
foggy jungle
I did have Steam verify the file integrity to replace the modified ones, but maybe totally uninstalling and reinstalling is what I need. Everest did install properly according to the terminal but Celeste just doesn't start after that.
Somehow, I didn't think to try running Celeste itself from the terminal to see what it says. I'll try that in a bit.
shut roost
you do need to have steam completely closed when you do that
warm cipher
i didnt really fully test the build from the zip 
maybe theres some issue there, i will try it myself tomorrow though
foggy jungle
I completely closed out Steam and ran Celeste through the terminal, and this was the error log it created.

System.ComponentModel.Win32Exception: SELinux execheap probe failed! Please ensure Everest has this permission, then try again
This occurs due to a permission error on Linux systems running SELinux, such as Fedora. To resolve this, use the following steps to allow Celeste to have the permissions it needs:
- Open a terminal window on the computer the crash happened on and run
sudo cat /var/log/audit/audit.log | grep -a execheap | grep -a Celeste- This searches the SELinux logs for entries showing that it denied Celeste
execheap, which is a permission that .NET needs to function properly.
- This searches the SELinux logs for entries showing that it denied Celeste
- If you see an output like
type=AVC msg=audit(1702580366.688:3126): avc: denied { execheap } for pid=353681 comm="Celeste" ..., then continue with these steps. If you get an error or no output, follow the instructions below to report the issue.- This output indicates that such entries exist in the logs, indicating that Celeste was indeed denied this permission.
- Run
sudo cat /var/log/audit/audit.log | grep -a execheap | grep -a Celeste | sudo audit2allow -M everest_core_fix- This finds the same entries as before in the SELinux logs, and then creates a rule that tells SELinux to allow Celeste to have this permission.
- Run
sudo semodule -i everest_core_fix.pp- This enables the rule that was created in the previous step, allowing Celeste to have the
execheappermission.
- This enables the rule that was created in the previous step, allowing Celeste to have the
After this Celeste should run without issue.
After following these steps, try launching Celeste again. If the issue is not resolved, please report this on Discord.

I'll try that out after work and report back. Thank you for all the help so far.

After following those instructions and launching Celeste, it'll show the Everest splash screen for a second saying it's launching the game and then just not do that. There's no log file or anything, but here's what it says in the terminal at that moment.

this seems like something outside of celeste
warm cipher
After following those instructions and launching Celeste, it'll show the Everest...
did errorLog.txt get updated again?
foggy jungle
I'll do that again and see if that file gets recreated.
After reinstalling Everest since I stupidly uninstalled it for some reason, it weirdly just doesn't show the splash screen at all now and instead complains about FNA being missing. I don't think there's a log file being made.
warm cipher
verify game files and reinstall everest i guess
foggy jungle
I reinstalled it from scratch again and it just works now, so problem solved, I guess?
