File "/usr/lib/python3/dist-packages/apt/package.py", line 1549, in
mark_install
fixer.resolve(True)
apt_pkg.Error: E:Error, pkgProblemResolver::Resolve generated breaks, this may
be caused by held packages.
the package cause this error is: libgbm1
I found as it happens, if it failed:
===
# apt-get install -s evolution-data-server libgbm1

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

The following information may help to resolve the situation:
The following packages have unmet dependencies:
evolution-data-server : Depends: libedataserverui-1.2-2 (= 3.36.4-0ubuntu1)
but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

However, If I
"apt-get install -s evolution-data-server libgbm1 libegl-mesa0"
Then there is no error
