I’d never tried customising AppImage updates in “Gear Lever” before.
It’s not very complicated: just follow the instructions and it works.
To try it out, I installed the penultimate version of Balena Etcher (1.19.23) in AppImage format.
“Gear Lever” did not detect a possible update.
So I copied the address of the latest version (1.19.25):
> https://github.com/balena-io/etcher/releases/download/v1.19.25/balenaEtcher-1.19.25-x64.AppImageype or paste code here
Then I set the source to “GitHub”, pasted the address into the box, and replaced the two occurrences of the version number with an asterisk, like this — just make sure you don’t delete any slashes or dashes:
> https://github.com/balena-io/etcher/releases/download/*/balenaEtcher-*-x64.AppImage
Last I saved it.
Clicking the button completed the update without a hitch.
Gear Lever is definitely the best and most practical application for managing AppImages!
