--- Comment #9 from Austin English austinenglish@gmail.com --- (In reply to Ben from comment #8)
On Ubuntu 18.04 (64 bit with i386 added) with wine-stable, which gives you wine 5.0.3 .NET installs fine. But on any more recent version or if you use wine-devel from winehq, the .NET installation hangs. Reproducibly.
That's not really helpful information (this bug was introduced in 5.18, which is way _after_ 5.0.3.
Still present in 6.0-rc1.
