bleep, bloop, I'm just a bot (boegelbot v20200716.01)
Please talk to my owner @boegel if you notice me acting stupid),
or submit a pull request to https://github.com/boegel/boegelbot fix the problem.

[boegel]

in-place updates like this are pretty painful...

Another solution to the source tarball for DB 18.1.32 no longer being available is to upload it at https://sources.easybuild.io, which is automatically considered as a fallback URL by EasyBuild.
That's only possible if the software license allows for redistribution though...

[dithwick]

I don't have a copy of that source file myself. Maybe someone else does (as you say, depending on the license).

[boegel]

DB 18.1.x is released under AGPL (+ UPL for examples) license, so sources can be redistributed -> see https://sources.easybuild.io/d/DB/

@dithwick With that, I think we can close this PR as well as #17318?

[dithwick]

Yep, that's fine with me of course
