Ubuntu add appimage to applications / dock / favourites

Tested with 18.04 and 20.04

Preparation

• sudo add-apt-repository ppa:appimagelauncher-team/stable

• sudo apt-get update

• sudo apt install dconf-editor menulibre appimagelauncher

Integration of .appimage

• Download an .appimage file
• Open it, should now open wirh appimagelauncher
  • Intergrate and move
  • The appimage is now in ~/Applications
• appimagelauncher creates a .desktop file in ~/.local/share/applications/, e.g. PrusaSlicer.desktop
• Ubuntu 20.04 does this automatically:
  • Google an icon for the app and save it to e.g. ~/Applications/prusa.png
  • Start "menulibre"
    • Set the downloaded image as icon
    • Check "Use start notification"
  • Add to dock/favourites:
    • Start "dconf-edior"
    • Navigate to org/gnome/shell/favorite-apps
    • Add your .desktop entry to custom value. Example:

      • ...
        'org.gnome.Software.desktop', 
        'PrusaSlicer.desktop'
        ]

• Log out and in again
