[Bug 1836083] [NEW] regression: dashboard totally broken in disco

[Harry Coin]

Public bug reported:

tl;dr-- ceph Dashboard regression in disco/eaon remains, reported fixes
are inappropriate/ineffective.

For well over a month, ceph's web interface 'dashboard' has been broken
in Disco, though it was working prior.  Another bug report claims fixes
have been released in eaon, however those fixes aren't even for the
version of ceph shipped in disco or eaon, and the nature of the fixes
are for bugs entirely unrelated to the cause of this regression.  That
claim of fixes is why the bug doesn't remain on the visible bug list.
However, it should be on the visible bug list.   The non-fix regards
details in report #1832105

The core of the problem has to do with a version of cython later than
what the dashboard module can cope with.  Upstream has fixes, but Ubuntu
hasn't backported them.

Error message:
ceph -s
...
health: HEALTH_ERR
...
Module 'dashboard' has failed dependency: Interpreter change detected - this module can only be loaded into one interpreter per process.
...
