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.
And it’s not only obscure software on obscure distros.
The Arduino IDE doesn’t run on Fedora 42. It just doesn’t work.
I personally don’t need it, I use ESP-IDF on Platformio, but Arduino is an incredibly common piece of software and one I would have expected to work flawlessly on Linux.
