Thank you for the PR!

I added a "Check for updates" button in the update settings that opens the "Releases" page of this github repo.

However #6049 states that the "Check for update"-button should trigger a update check and not open the GH releases site.

In my opinion we now have 2 options:

• Make the check for update-button do a update check
• Rename the button to something like "Show releases" - however
  • it's not clear if we require something like this in the first place
  • this should be done in a separate PR (and this one should be closed) as this would then close Manual update check button in the Updates page of the app #6049 when merging.

@litetex I got the check for updates button to do a correct check update. But I have a question, is it okay to have no way to test it in a debug build as I have it now ? I tested it on my side, but with a quick and ugly fix.

@vhouriet
I think the reviewer (currently none) has to determine if this is okay or not.

When I review this issue (hopefully in the next time) then I will come back to this 😄

PS: Shrunk the image in the issue description a bit (less scrolling 😉)

LGTM

Seems to work as expected when isReleaseApk is set to true.

I also did some minor fixes regarding

• dead code
• naming (GithubAPK → ReleaseAPK)
• code format

and rebased the branch so it's up-to-date.
