Discussed in https://github.com/cockpit-project/cockpit/discussions/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

@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.
