Bug Description

Signal-desktop wasn't launching, so I tried removing it and reinstalling it. The error it's throwing looks quite similar to the error that was happening when I was launching signal before.

Steps to Reproduce

Attempt to (re)install signal-desktop.

Actual Result:

error: cannot perform the following tasks:
- Run configure hook of "signal-desktop" snap if present (run hook "configure": 
-----
free(): double free detected in tcache 2
/snap/signal-desktop/346/snap/command-chain/hooks-configure-desktop: line 43:  2176 Aborted                 (core dumped) "${SNAP_DESKTOP_RUNTIME}/usr/bin/fc-cache" --force --system-only --verbose
-----)

I looked for all instances of /usr/bin/fc-cache on my machine, and didn't find anything inside those folders.

Expected Result:

Well, I'd expect signal to work normally. It's working on my other ubuntu 20.10 machine, though, so mayhap there's something funny about this one. Not sure what to try aside from reinstalling Signal, though.

Platform Info

Operating System:

Hey @RojjaCebolla
the snap version of Signal desktop is not maintained by signal devs, but by the snap community

Since you are having installation problems, I guess it's more related to snap than to signal
(but I could be wrong)

You should try to install the normal deb package of signal
If this works, then it is snap related

huh, i guess i assumed .deb would be something to download and update manually, i didn't realize it'd be added as an apt source. so i'm using that, and it works now, thank you!
