Hi @pixel,
I found this approach already. However, I got and still get with your settings dependency errors. I discarded this way, since I thought this might be not the right way:
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:
bareos-client : Depends: bareos-bconsole (>= 19.2.7-2) but it is not going to be installed
bareos-filedaemon : Depends: bareos-common (= 19.2.7-2) but it is not going to be installed
bareos-traymonitor : Depends: bareos-common (= 19.2.7-2) but it is not going to be installed
Depends: libqt5core5a (>= 5.9.0~beta) but 5.7.1+dfsg-3+deb9u3 is to be installed
E: Unable to correct problems, you have held broken packages.
If I add bareos-bconsole and bareos-common to the installation command (and remove the traymonitor), I end up with this:
The following packages have unmet dependencies:
bareos-common : Depends: libc6 (>= 2.27)
But the installed version is lower:
dennis@ucs01:~$ dpkg -l | grep libc6
ii libc6:amd64 2.24-11+deb9u4 amd64 GNU C Library: Shared libraries
