Relative to what ships with 19.04, you need to upgrade to
snapd 2.39.2+19.04 for Electron Player to show up in the "Other" category of the menu. Additionally, this upgrade will need to be in place in order for a functional version of Electron Player (2.0.7 rev 9) to be installed correctly.
snapd in Discover does not seem to provide the fix, so to upgrade
- Open System Tools → Qterminal
sudo apt update && sudo apt -y install snapd and press Enter
- When asked for your password, enter it and press Enter
While you're there you can easily install Electron Player from the terminal:
sudo snap install electronplayer and press Enter
- Enter your password if asked and press Enter
- When completed, run it by entering
electronplayer and pressing Enter
Since you already have Electron Player installed, you could upgrade
snapd as above, but you would still face problems if you try to run Electron Player:
(electronplayer:2917): Gtk-WARNING **: 00:15:17.454: cannot open display: :0
To ensure that everything is working correctly, remove then install Electron Player:
sudo snap remove electronplayer && sudo snap install electronplayer.
