To be fair to Canonical, those messages can be disabled by deleting /etc/apt/apt.conf.d/20apt-esm-hook.conf
, but that’s still kinda unacceptable IMO.
They should’ve just disabled the messages unless you actually attached a pro license
(disclaimer: I mainly use kubuntu as my debian-based distro of choice, because gnome/gdm3 makes my eyes bleed)
Agreed. Gotta make the community friendly somehow
