A script that generates a custom AppImage from Debian or from a PPA of your choice for the previous (not the oldest) and still supported Ubuntu LTS
wget https://raw.githubusercontent.com/ivan-hc/AppImaGen/main/appimagen
chmod a+x ./appimagen
./appimagen [package1] [package2] [package3] [package4] ...
During the build the script will ask you to choose between Debian or the previous Ubuntu LTS:
- By choosing debian the script will ask if you what branch you want choose (stable, testing, oldstable, oldoldstable, unstable...);
- By choosing ubuntu the script will ask if you want add one or more PPAs.
Example, suppose you want to build the Chromium web browser from the ppa:savoury1/chromium including the language pack:
./appimagen chromium-browser chromium-browser-l10n
Then choose 2 (i.e. "Ubuntu"), press Y to add a PPA and copy/paste savoury1/chromium (more PPAs are listed at https://launchpad.net/~savoury1).
During the build you will choose if you want to include libunionpreload, if you want to rely also on the system libraries and if the AppImage has a binary executable into another $PATH.
"AppImaGen" is a script extracted and compiled from my workflows in building my AppImage packages for "AM" Application Manager and AppMan and redistributed for you as a standalone script.
