At Tue Jan 18 23:44:56 UTC 2022, at the bottom of https://lists.archlinux.org/pipermail/arch-general/2022-January/049521.html , I wrote that my understanding is that checkupdates -d is equivalent to pacman -Sywu && pacman -Su . I haven't read checkupdates manual page. It could be that other then a safe upgrade it does additional work. I still haven't read checkupdates manual page. Rereading mpan, who is the author of the message I responded to, message, I should have wrote that my understanding is that checkupdates -d is equivalent to pacman -Sywu . Not to pacman -Sywu && pacman -Su . -- jadon
