Unable to install libgtk-4-dev on 22.04 LTS

[Martin Ammermüller]

When trying to install libgtk-4-dev, apt throws an error due to dependency problems:

martin@Nike:~$ sudo apt install libgtk-4-dev
Reading package lists... Done
Building dependency tree... Done

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:
 libgtk-4-dev : Depends: gir1.2-gtk-4.0 (= 4.6.2+ds-1ubuntu2) but 4.6.3+ds1-0ubuntu1 is to be installed
                Depends: libgtk-4-1 (= 4.6.2+ds-1ubuntu2) but 4.6.3+ds1-0ubuntu1 is to be installed
E: Unable to correct problems, you have held broken packages.

There seems to be a versioning problem.

None of my packages seem to be on hold:

martin@Nike:~$ dpkg --get-selections | grep hold
martin@Nike:~$

I have a kind of similar problem might be related.
On a fresh ubuntu server install on my workstation I have unmet dependencies when installing ubuntu-desktop-minimal.

libmutter-10-0 : Breaks: libgtk-4-1 (< 4.6.3+ds1-0ubuntu~) but 4.6.2+ds-1ubuntu2 is to be installed

I've also seen that libgtk-4-1 has version 4.6.5 on phased update.

setting APT::Get::Always-Include-Phased-Updates to true seems to have solved it for me.

[Martin Ammermüller (maammer)]

Adding the line

APT::Get::Always-Include-Phased-Updates true;

to a custom config file in /etc/apt/apt.conf.d/ worked for me, too. I'm not sure of the implications of this workaround, though.
