Title:
cannot install libegl-mesa0 on 22.04.2 LTS
Status in mesa package in Ubuntu:
Confirmed
Bug description:
# Summary
`apt install libegl-mesa0` does not install it due to a dependency
conflict in the apt repo.
libegl-mesa0 has dependency to explicit versions of:
* libgbm1 (= 22.2.5-0ubuntu0.1~22.04.1)
* libglapi-mesa (= 22.2.5-0ubuntu0.1~22.04.1)
But the latest in ubuntu repos are versions 22.2.5-0ubuntu0.1~22.04.2.
# Expected behavior
These closely linked packages to be up-to-date in the Ubuntu repo.
# Workaround
It is possible to install libegl-mesa0 by first downgrading the
conflicting package versions:
apt install libgbm1=22.2.5-0ubuntu0.1~22.04.1
apt install libglapi-mesa=22.2.5-0ubuntu0.1~22.04.1
and then installing it normally:
apt install libegl-mesa0

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:
libegl-mesa0 : Depends: libgbm1 (= 22.2.5-0ubuntu0.1~22.04.1) but
22.2.5-0ubuntu0.1~22.04.2 is to be installed
Depends: libglapi-mesa (= 22.2.5-0ubuntu0.1~22.04.1) but
22.2.5-0ubuntu0.1~22.04.2 is to be installed
E: Unable to correct problems, you have held broken packages.`
```
1) Is the hard dependency (=) really necessary?
2) Or should I just downgrade existing libglapi-mesa and libgbm1
installs? The difference is minor patch version only so I am hesitant
to do so (there must have been a reasons for the .2 patch).
