It looks like a new version was provided today, and since then I can’t run it. I removed it from the Ubuntu store, then reinstalled it, and from the cli am now getting:
$ notepad-plus-plus
Installing application…
Running hook ‘/snap/notepad-plus-plus/373/sommelier/hooks/pre-install’
Starting application…
wine: failed to open “/home/erik/snap/notepad-plus-plus/373/notepad-plus-plus/notepad-plus-plus.exe”: c0000135
Seems to be an issue with the notepad++ repo, not with wine, as other snaps that use wine still work.
This is the GitHub for snap’s notepad++ https://github.com/mmtrt/notepad-plus-plus
It should be working now, this happened due to late upload of new version in upstream github repo and auto trigger had build snap earlier hence no files of npp were added.
