On a default image of ubuntu 24.04, upon connecting via rdp, there are errors in the journal,
gnome-remote-desktop-daemon[2650]: [22:04:03:071] [2650:4874] [WARN][com.winpr.negotiate] - AcceptSecurityContext status SEC_I_CONTINUE_NEEDED [0x00090312]

https://askubuntu.com/a/1462215 suggests it is because of non-ascii chars in the password, and indeed, when I change the rdp connection password in the system settings, it works.
Now I tried upgrading to the package gnome-remote-desktop_46~rc-0ubuntu2_amd64.deb , but it depends on a range of other packages for which I have no source, i.e. libfreerdp3-3 (>= 3.1.0) et al.
Now,
a) might gnome-control-center suggest an ascii-only password on 24.04 because otherwise we will have a default-broken installation,
b) might the update to gnome-remote-desktop_46 come in time for 24.04 ?
