The release notes of Hestia 1.4.0 state, that Ubuntu 16.04 LTS isn’t supported anymore:
NOTE: Ubuntu 16.04 (Xenial) is no longer supported as it has reached EOL (end-of-life) status.
But the homepage https://hestiacp.com/ still shows Ubuntu 16.04 LTS in the list of supported operating systems.
Has the homepage not yet been updated, or is 16.04 still supported?
