unable to install on SP8 Ubuntu 22.04

[g66it]

I followed all the steps to install the whole kernel but for iptsd I get the following error:

me3@me3-Surface-Pro-8:~$ sudo apt install iptsd

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:
 iptsd : Depends: libcairomm-1.0-1v5 (>= 1.14.4) but 1.12.2-4build3 is to be installed
E: Unable to correct problems, you have held broken packages.

I just installed Ubuntu 22.04 (which the installation instructions say it should be okay) on a SP8, clean and minimal install.
I checked the wiki for the SP8 and I don't see this issue described.
I am not much (yet) into Linux so I am not sure that I understand what I should do to solve the above dependency issue. Nor if I need to install a different version of iptsd (and if so, how!).

Thanks!
