Had this issue where after I logged into my Ubuntu desktop all Snap apps icons do not show properly. Instead I see a plain icon in place of what the app icon should be. Have you the same experience?
This might have been fixed in later Ubuntu LTS releases, I really don’t know. But I am still on 16.04 Xenial Xerus until its EOL. Also, the reason is that I love the Unity Desktop. The Gnome Shell replacement just doesn’t cut it for me.
I have been looking for a solution on this issue for some time. The 2 main things people point out are:
– Add /snap/bin to the /etc/environment file, and;
– Something to do with the profile.
Neither of those solutions worked for me. But it did work for others according to what I have read so far.
ANSWER
To fix this icon issue, create a symlink of the Snap’s .desktop shortcut file to your user’s .local/share/applications directory.
It is as simple as that. Once done the problem will go away, and you will be left with a nice-looking icon that came with the Snap installation. This won’t go away on following restarts.
