In an OMV 6 install on vm I have a couple of packages hanging around in Update Manager for a week or so after running updates. Here is what returns when I select install:
Code
Reading package lists...
Building dependency tree...
Reading state information...
Calculating upgrade...
The following packages have been kept back:
linux-image-amd64
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
What little I am doing with the test install is still working fine. I just wanted to note the issue to see if there is something wrong.
