Hello @YamiYukiSenpai!
This seems very odd, I tried booting up a clean live image of Kubuntu 20.04 and had no problems installing and launching Poddr as a snap.
Are you sure Poddr is the issue? Do other snaps work as intended and has Poddr worked before?
If other snaps are working could you install the snap "snappy-debug" and run that in another terminal before trying to launch the Poddr snap? This should output better info regarding why a snap won't launch. You will see a few DBus issues but those are at this point expected.
Never mind. Something must've been wrong with the local snap directory. I removed poddr in ~/snap. That fixed it.
For some reason, it's not launching again. After my previous comment, I didn't launch Poddr until today, and it's not launching. The only way I get it to launch is by deleting the poddr directory in ~/snap.
Hi again @YamiYukiSenpai 😄
Could you try the steps I talked about in my previous comment and then get back to me here?
- Did earlier versions of Poddr work correctly or is it a new installation?
- Is Poddr the only snap affected by this issue on your system?
- Could you install the snap called "snappy-debug" and launch it in a terminal and then try to launch Poddr in another terminal? This could give some hints about what is causing your issues.
- You could also try to use the AppImage or .deb package and see if those work as expected.
I have the same bug on Zorin 15.2(Ubuntu 18.04)
1. Did earlier versions of Poddr work correctly or is it a new installation?
I do a new installation.
2. Is Poddr the only snap affected by this issue on your system?
Yes. Others snap apps work fine.

Suggestions:
* adjust program to use $SNAP_DATA
* adjust program to use /run/shm/snap.$SNAP_NAME.*
* adjust program to use /run/snap.$SNAP_NAME.*
* adjust snap to use snap layouts (https://forum.snapcraft.io/t/snap-layouts/7207)
4. You could also try to use the AppImage or .deb package and see if those work as expected.
I installed the AppImage version and it’s working fine.
@nocttuam Thanks a lot for this info, exactly what I was looking for!
I will take a look! 🕺
