Hi
After rebooting as per pos #38 I got libsnmp-base error
CodeAlles anzeigen~# apt-get purge openmediavault-omvextrasorg resolvconf Reading package lists... Done Building dependency tree Reading state information... 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: libsnmp-base : Breaks: snmp (< 5.7.3+dfsg-5) but 5.7.3+dfsg-1.7+deb9u1 is to be installed E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
It seems you are still using Debian 9 package repositories in Debian 10. Fix that and the error should be gone.
