Pacman.conf is being edited on the date of return, specifically I returned to 10.08.2022 when everything was ok. Then I returned to 09.10 when nothing worked. I found out that I had a breakdown on 09.10. I returned the distro to 08.10 and after that did a total update of the distribution. You gave a solution, but it doesn't help because now a new problem has appeared and the alarm does not exist in the panel and does not work, it is empty -- You are receiving this mail because: You are watching all bug changes.
