I really am a Linux newbie, but I’m trying to make a running system for my laptop - I’ve installed Antergos Plasma, it seems great, took it away for a week on holiday (email, web, playing movies etc - usual holiday stuff) all fine.
On my return today I tried to update (via terminal - sudo pacman -Syu) and my screen filled with “error: could not open file /var/lib/pacman/sync/core.db: Unrecognised archive format”.
I followed the instructions in the post https://forum.antergos.com/topic/6984/error-with-antergos-keyring about refreshing the keyring - this appears to have allowed me to update via Pamac which now reports “Your system is up-to-date” but if I try to update via terminal, I still get the screen full of lines saying “error: could not open file /var/lib/pacman/sync/core.db: Unrecognised archive format”.
I would like to be able to fix this but, more important to me is this - does this sort of thing happen all the time? I am a new Linux user but an experienced computer user - I don’t want a ‘flaky’ system or something which will require vast amounts of time to keep running (after all, I already have Windows for that ;-) - would I be better-off to cut my losses and move to a more beginner-orientated distro (Ubuntu, Mint etc) rather than persist with this Arch-based one?
I would really appreciate an answer here - I don’t want to return to Windows or buy a MacBook, but I need a machine which will work and update without the need to ‘fix it’ every time.
