@stormi I'm also getting error on some VMs while trying to export a disk and also trying to even start some VMs from NFS (that were fine before).

I'm seeing 30 updates as well but they're installed and seem to be working fine on my test systems.

I think I only listed sources packages (which contains several binaries sub-packages having the same versions), so that's expected
BTW thank you for reactivity on testing
