I don’t know if I’m the only one, but in the last few days I’ve been seeing the following message more and more often:
500 Can't connect to aur.archlinux.org:443 (Network is unreachable)
Unable to GET https://aur.archlinux.org/rpc?
Unable to get info for AUR packages...
- …
A few minutes later it works (or not)
I know that this is not Manjaro’s responsibility. But maybe it will reassure others who have the same problem. After all, it’s enough to repeat the process later.
