do-release-upgrade fails due to lack of inodes

[Neil Wilson]

When upgrading from Trusty to Xenial it is possible to have a disk that is half empty but has run out of inodes due to uncleared kernel updates.

This of course causes the upgrade to fail with catastrophic and irreversible results

Not sure what pre-flight checks upgrader does, but checking for sufficient inodes as well as disk space (plus checking if the apt cache is ok like unattended upgrades does) might be worth doing.

In the meantime back to trying to recover the corrupted server... :-)
