Comment 5 for bug 1993213

On my 22.04 Ubuntu (upgraded over multiple years) with the broken Frescobaldi already installed, I have the exact same error about python3-qpageview (but not the fluidsynth recommendation, strangely enough):

```
$ sudo apt install frescobaldi/jammy-proposed
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Selected version '3.2+ds1-1~ubuntu0.22.04.1' (Ubuntu:22.04/jammy-proposed [all]) for 'frescobaldi'
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 frescobaldi : Depends: python3-qpageview but it is not installable
E: Unable to correct problems, you have held broken packages.
$
```

(Did a `sudo apt update` which also updated jammy-proposed just now, Monday December 19 2022 at 08:12 UTC.)
