Updating to Cockpit 329 removes cockpit-pcp

[martinpitt]

Discussed in #21343

^{Originally posted by compbl November 27, 2024}
When I attempt to update to Cockpit 329 via the software updates page I am receiving an error "The following packages have unmet dependencies: cockpit-bridge: Conflicts: cockpit-pcp" I am assuming I have to remove cockpit-pcp, but cannot find how to do that. Any help would be appceiated. Running on Ubuntu 22.04.5 LTS

Thanks

I'm starting from the basics, booted a clean 22.04 machine with some cockpit packages installed:

# dpkg -l | grep ^ii.*cockpit
ii  cockpit                                          264-1ubuntu0.22.04.1                    all          Web Console for Linux servers
ii  cockpit-bridge                                   264-1ubuntu0.22.04.1                    amd64        Cockpit bridge server-side component
ii  cockpit-pcp                                      264-1ubuntu0.22.04.1                    amd64        Cockpit PCP integration
ii  cockpit-system                                   264-1ubuntu0.22.04.1                    all          Cockpit admin interface for a system
ii  cockpit-ws             

and apt itself can do it fine:

 apt upgrade -t jammy-backports cockpit

Setting up your scenario (older backport) is a bit more effort, I'll do that later.

so do i need to remove cokcpit-pcp fresh installation ? just do apt install cockpit cockpit-sos and that's it? cause right now i don't get pcp

[martinpitt]

@emaayan Not sure what you mean, but with recent versions there is no cockpit-pcp, right. If you want historic metrics, install python3-pcp. The metrics page will also do this for you with on-demand installation.

[martinpitt]

[martinpitt]

Heh, ok -- attaching images via email is apparently not working 😅

[emaayan]

good it would be less embarrassing cause at the time i didn't catch you previous reply about the cockpit itself not being pinned so now i have cockpit 14 and the rest of the cockpits at 3.29.1

[emaayan]

@martinpitt
still a problem, and missing pcp

[LeLawnGames]

Any fixes for this yet? My existing cockpit instance is unable to have updates installed because of the cockpit-pcp error.

[martinpitt]

@LeLawnGames are python3-pcp and pcp installed? These are what "Install PCP support" should do.

isn't there a way to install them from the start?

I had a similar issue on my install, I was able to clear the failing services by running:

sudo apt-get upgrade pcp
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Calculating upgrade... Done
The following NEW packages will be installed:
  libpcp-pmda-perl libpcp-trace2 libpcp-web1 libpfm4 pcp

Not sure if this helped, but i did enable both of this and install which also seemed to install some additional packages.

My dpkg -l 'cockpit' output:

Yeah it's the above error I keep encountering -- Conflicts: cockpit-pcp

[LunarTwilight]

I was having a somewhat similar issue with no historical logs, installing pcp helped, as it was uninstalled by upgrading.

[berwhale]

sudo apt remove cockpit-pcp fixed the issue for me. I had to reboot afterwards to get the metrics back.

worked for me too!

[LeLawnGames]

Yep worked for me!

[kevinceegross]

sudo apt remove cockpit-pcp fixed the issue for me as well. Thank you!
