Seems to be an issue that is related to disk encryption. The system startup properly and I do not see any bad behaviour, however do anybody have an idea how to fix

I get the same warning on Ubuntu 16.10 with encrypted LVM. I have not found a solution but, for what it's worth, it appears related to the Debian bug reported on 16 Nov 2016.
My server works fine so I'm hoping it's a minor bug that will be fixed in upcoming Ubuntu releases.
