How to Install AfterShot 3 on Ubuntu

Symptoms

AfterShot's install may complain about missing dependencies when installed on Ubuntu 20.04 and later.

Resolution

Here are the steps to install AfterShot Pro 3 on Ubuntu 22.04:

1. Browse to https://www.aftershotpro.com/en/support/updates/
2. Click "Linux Debian" at the right:
   
3. Click "AfterShotPro3-system-Qt.deb" to download AfterShot:
   
4. Open a Terminal Window and enter these commands. You will see several warnings / errors after the dpkg command. This is expected. I'm assuming the file was saved to your ~/Downloads folder:
   cd ~/Downloads
sudo dpkg -i AfterShotPro3-system-QT.deb
sudo apt install -f
5. Close Terminal
6. Click Activities, type AfterShot and run the program.
