Ubuntu is likely used by 10s of millions of servers and desktops. I'm not sure why this kind of breakage is considered acceptable. Very confusing.
Users who need stability should use the LTS releases. The interim releases have always been more experimental, and have always been where Canonical introduces the big changes to ensure everything's mature by the time the LTS comes around.
> Every six months between LTS versions, Canonical publishes an interim release of Ubuntu, with 25.10 being the latest example. These are production-quality releases and are supported for 9 months, with sufficient time provided for users to update, but these releases do not receive the long-term commitment of LTS releases.
and this is probably a net positive, there's now an early adopter for the project, the testsuite gets improved, and the next Ubuntu LTS will ship more modern tools
I was expecting that they would be concerned about bugs in the untested parts!
