After installing an app in ubuntu, it appeared twice in "all apps" drawer. I fixed that by running ``` rm com.nameoftheapp.desktop ``` inside /usr/share/applications/ and leaving only the nameoftheapp.desktop file. Back to the basics of the filesystem

I have found other users reporting the same, specifically for Viber, not only on Ubuntu 24.04.4 LTS but other distros as well, so it is a confirmed workaround.

> cd /usr/share/applications
> ls -l
com.viber.Viber.desktop -> viber.desktop

> rm com.viber.Viber.desktop
