We love to praise linux constantly and tell everyone to change to it (they should) but what are your biggest annoyances ?
Mine would be, installing software (made even more complex by flatpaks being added, among the 5 other ways there already were to install software) and probably wifi power management issues.
It’s a separate package tool that works on every distribution. Usually Debian derivatives use
apt, Redhat ones usednfetc. Flatpaks work everywhere.
