Nextcloud-desktop 3.4.0 repository issue

The Ubuntu 20.04/focal repository at is delivering 3.4.1 as it should. I was surprised for find our new Ubuntu 22.10//impish is still only offering old 3.4.0. Very odd. As repositories are our preferred method of upgrading can this be remedied please?

We were nearly inadvertently upgraded to Nextcloud 23.0.1 which may have put things at risk with the time-stamp issue on 3.4.0 clients.
