[Bug 2146422] Re: Installer UI crashed with ServerDisconnectedError

[Dan Bungert]

Please provide full steps to reproduce.  For example, these logs suggest
any interaction with the installer will produce this failure, when it's
plainly more specific than that.

Please provide steps on what you're doing within the installer.
Mentioning that refresh was taken is a big deal.

Please provide what ISO you're using.  I had to reverse engineer this
starting point by looking at the logs and observing what subiquity snap
was used to start and what snap was refreshed to.  So the starting iso
is 20260323 or so.  Also it's kind of strange to use the non-beta ISO
and report it as a beta blocker.
