If you are using either of the v17.0rc1 appliances or any TurnKey Linux appliance with a Debian Bullseye/11 base OS, please be sure to clear your apt caches - after I push the infrastructure updates. Check the first line of this post to see whether the updates have been applied yet or not.
Note: Previous and existing TurnKey Linux stable releases are not affected!
If you experience any issues which you think may be related to these updates; please let us know, giving as much detail as possible.
