Details

When trying to upgrade a system that has:

– element-desktop 1.10.8-1 (or actually anything recent)
– electron 17.2.0-1 (or any 17.x version)

it fails with:

error: failed to prepare transaction (could not satisfy dependencies)
:: installing electron (18.0.1-1) breaks dependency 'electron17' required by element-desktop

electron was upgraded to 18.0.1, and it thus now provides electron18. At the same time, an electron17 package was added to the repo… but apparently pacman cannot solve this.
This task depends upon

(Of course there is a workaround of `pacman -Rdd electron` and then upgrading, but a proper solution would be better)

This is covered in our codebase with an XFAIL on this test:

OK, so known. The proper workaround seems to be `pacman -Syu --asdeps electron17` instead of the one I’ve suggested above.

Another workaround would be to bump the pkgrel on element-desktop so that it's included in the update transaction. No manual intervention required that way.

Ah, good to know. Bumping right away.

Still I see dependency on electron17.

@zeroconf: element-desktop does depend on electron17, that’s not the issue.

CCing electron maintainer so they're aware of the issue and rebuild all packages that depend on the last electron version every time the major version changes

@Allan Would it work if instead of depending on electronversion packages depended on electron==version and electronversion packages provided electron==version? Or would it be the same issue?
