I’m trying to update a computer for a relative who hasn’t done so for about a year. I used the TTY instructions and all downloaded. It asked if I wanted to import a key from integral@archlinux and I entered yes. Then 3 of the 1135 packages were listed as having a key that was “unknown trust”. The packages were sane, xournalpp, and lib32-libldap.
Would you please point me to how I might get these corrected because this prevents any updates from being performed? Thank you.
I’d remove those packages and re-install them after the update.
There may be a few .pacnew files to tend to as well … 
Note: I’ll check out those packages when I get home and am back on my Manjaro system. So it may be worth hanging on for about an hour or so.
Edit: Typos
Thank you. I started trying to remove them but the lib32 one just keeps going to a new dependency which requires the deletion of another lib32 that requires that as a dependency. After about five iterations of that, I stopped because not sure that is a good approach. If so, I will continue. Thanks.
My first guess is that the mirrors used by this installation haven’t been updated or refreshed for a very long time, either.
You might try (preferably from a TTY entered outside of the GUI);
pamac update --no-aur --force-refresh
Wait for that to successfully complete, and then reboot. All being well, that might allow future updates to complete.
A brief mention that mirrors should ideally be refreshed as a part of regular maintenance; an example using pacman-mirrors is:
sudo pacman-mirrors --continent
which limits the selection to more local regions.
From a previous Update announcement;
I would also start with refreshing mirrors.
If it doesn’t work, this in the section “errors about keys” will.
Thank you. The pamac update … seems to have fixed it. Everything updates except the print driver plug-in for HP-LIP and xsane. I don’t know why they are there though, they are AUR packages but I don’t know why we added them. So, 2 left out of 1135 is great. Thank you.
Some HP printers require an extra plugin; I don’t need it for my printer so I have never used it. If you need it, you could try re-building (pamac build hplip-plugin) and report any errors. There is a list here of printers which need it:
