I believe if we just untag the newer R, it will still be the case that "no R- package installs, nothing that transitively buildrequires it builds", because the last R build was not against ICU 71.1. So we would probably also need to revert the R 4.2 bump in R's repo (or move it to a separate branch) and rebuild R 4.1 against ICU 71.1?

Alternatively we could untag the entire ICU 71.1 update, which is huge, until this is sorted, I guess.

untagged from both f37 and eln:

$ koji untag-build --force f37 R-4.2.1-2.fc37
$ koji untag-build --force eln R-4.2.1-2.fc37

It would be good to bump and rebuild R in the side tag to make sure it has a higher release number than the build that was just untagged.

icu has a compat package, so R packages should still install

At least that is what I've been told.

Sorry, I didn't see your comments before doing this, but I believe it should be fine now because there's a libicu69 compat package that provides the old ABI that the older R build that's now in rawhide is linked with.
