SOLVED! Thanks for your help, as in many things, the problem is in the
details:
aptitude shows what the problem is:
Unua:~# aptitude install x2goserver
The following NEW packages will be installed:
libnx-xcomposite1{a} libnx-xdmcp6{a} libnx-xfixes3{a} libnx-xinerama1{a}
libnx-xpm4{a} nxagent{ab} x2goagent{a} x2goserver x2goserver-extensions{a}
x2goserver-xsession{a}
0 packages upgraded, 10 newly installed, 0 to remove and 2 not upgraded.
Need to get 2,182 kB of archives. After unpacking 7,347 kB will be used.
The following packages have unmet dependencies:
nxagent : Depends: libnx-xdamage1 (<
2:3.5.0.32-0x2go1+git20160614.734+jessie.main.1.1) but
2:3.5.0.32-0x2go1+git20160614.734+wheezy.main.1 *is installed.*
Depends: libnx-xrandr2 (<
2:3.5.0.32-0x2go1+git20160614.734+jessie.main.1.1) but
2:3.5.0.32-0x2go1+git20160614.734+wheezy.main.1 *is installed.*
Depends: libnx-xtst6 (<
2:3.5.0.32-0x2go1+git20160614.734+jessie.main.1.1) but
2:3.5.0.32-0x2go1+git20160614.734+wheezy.main.1 *is installed.*
------------------
Now you will see that it says IS INSTALLED. Meaning: there are remants of
old libs still hanging around from the wheezy install.
Now let's see what apt-get says:
The following packages have unmet dependencies:
nxagent : Depends: libnx-xdamage1 (<
2:3.5.0.32-0x2go1+git20160614.734+jessie.main.1.1)
but 2:3.5.0.32-0x2go1+git20160614.734+wheezy.main.1 *is to be installed*
Depends: libnx-xrandr2 (<
2:3.5.0.32-0x2go1+git20160614.734+jessie.main.1.1)
but 2:3.5.0.32-0x2go1+git20160614.734+wheezy.main.1 *is to be installed*
Depends: libnx-xtst6 (<
2:3.5.0.32-0x2go1+git20160614.734+jessie.main.1.1)
but 2:3.5.0.32-0x2go1+git20160614.734+wheezy.main.1 *is to be installed*
This is plain simple wrong. I checked and these libs are in fact installed,
so I removed them and now I could install x2goserver without a problem.
apt-get is saying that they will be installed, but not that THEY ARE
installed, kind of misleading.
I have had the experience in the past, that aptitude just does a little
more, is a little more intelligent and can sometimes help you out of a
pinch that apt-get left you in.
Thanks for the suggestion and help, the problem was solved really fast.
