PSA: Dropping Support for Ubuntu 18.04

Originally published at: PSA: Dropping Support for Ubuntu 18.04 – Pi-hole We hate to have to do this so suddenly, but due to the changes made to the FTL build containers, and issues reported to us on Discourse we will need to drop support for Ubuntu 18.04 going forward. While Ubuntu 18.04 is still LTS, there are still two further releases (20.04 , and 22.04), so we would encourage users to upgrade to one of those. That said, there were no breaking changes in FTL for v5.17, please revert …

Thanks for this. I revert to 16.3. All seems right.
