When I do sudo apt-get upgrade, I have the following message:
WARNING: PV /dev/sda3 in VG ubuntu-vg is using an old PV header,
modify the VG to update.
What can I do?

'VG' in the warning means volume group. This is applicable to systems using logical volume management. 'PV' stands for physical volume, that is the actual partitions on disk(s). Headers contains information about the volume group's layout which can be used for data recovery.
You can try to resolve this with the tool vgck, which checks volume group metadata, and can correct it with the --updatemetadata option. You need to give the name of the volume group mentioned in your warning - in your case it says that the physical volume /dev/sda3 in volume group ubuntu-vg is using an old header, so you need to use that volume group as the argument:
sudo vgck --updatemetadata ubuntu-vg
This will issue the same warning; to prove that it fixed the issue, simply run
sudo vgck --updatemetadata ubuntu-vg
once more, and the warning should not appear.

10Ensure that you replace
ubuntu-vgwith the actual volume group name from your own specific error message, as it may vary. ;-) Jan 26, 2021 at 21:37 -
