I also thought it would be a regular network problem at first, but actually I have troubles with installing AUR packages since a week or so.
I only didn’t bother to check the actual error that appears in the console, that’s why I only report it now.
I still get the same error message for every package i tried.
that is where the updater (pamac or whatever else) will try to get their information from
if it is out of date - the data can’t be accessed
it more than likely is as simple as that …
understanding the infrastructure behind all of this working smoothly is helpful in understanding the error messages / the ways it may fail to “deliver”
