# df -h /boot
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 1G 1G 0G 100% /boot
Cause
The /boot partition has no space left to proceed with the needed installation or upgrade.
Resolution
Resize the /boot mounted partition to add some free space.
Warning: Editing Boot Partitions can be dangerous and cause damage to the Server. Plesk does not manage partitioning.
This should be done by a System Administrator or by the Server Hosting Provider.
Before proceeding further create a Full Server Snapshot.
