Dear Maintainer,

When upgrade from bookworm, the `cockpit-bridge` replaces `cockpit-pcp`. But
the function provided by `cockpit-pcp` (which used to be a sug package of
`cockpit` package) cannot be simply replaced by `python3-pcp`. Due to the
missing of `pcp` package, cockpit cannot work properly.

Maybe directly suggest `pcp` as a dependency can solve the problem.

Hello Itsuki,

sorry for the late reply!

Itsuki Moroshima [2025-08-10  2:18 +0800]:
*read* existing PCP data if it already exists. But it is not Cockpit's place
(especially not the bridge component) to suggest installing an active service
component, as that changes the system behaviour -- and in a quite intrusive way
in PCP's case.

So IMHO the earlier "Depends: pcp" of the former cockpit-pcp package was too
strong and wrong.

The intention is that if `pcp` is missing, and the admin actually wants the
service, the page will show an on-demand install button in the UI. However,
this only works if `packagekit` is installed.

How did that actually "break" your upgrade? Did apt remove the "pcp" package as
it was only a former dependency of cockpit-pcp? Then I suppose a `Suggests:`
may not help, but Recommends: would really be too strong. Then we'll have to
live with that error, and I'll just add a NEWS entry instead.

Thanks,

Martin

Hello,

I never got a reply for the moreinfo request, this is difficult to fix, and at
any rate it's obsolete now: we can't realistically fix oldstable → stable
upgrade bugs any more. Thus closing.
