[SOLVED] Pacman refuses to upgrade due to missing key

Starting today, I get this error messge when trying to upgrade via pacman

error: key "7A4E76095D8A52E4" could not be looked up remotely
error: required key missing from keyring
error: failed to commit transaction (unexpected error)

Generating a fresh keyring (https://www.archlinux.org/news/gnupg-21 … n-keyring/) doesn't resolve the problem.
Anyone else getting an error similar to this?
Any ideas on resolving the issue?

Re: [SOLVED] Pacman refuses to upgrade due to missing key

One should follow https://wiki.archlinux.org/index.php/Pa … mport_keys in case reinstalling pacman-keyring wouldn't sufice.

Using unofficial repos? May have a sig-key, which may need to be re-added. https://wiki.archlinux.org/index.php/Un … positories
eg for Graysky's repo-ck: https://bbs.archlinux.org/viewtopic.php … 1#p1485841

Actually it was an upgrade. I guess you should always update archlinux-keyring first. Thanks for pointing it out.

Re: [SOLVED] Pacman refuses to upgrade due to missing key

sudo pacman -S archlinux-keyring && sudo pacman -Syu

@ayr0 - Thanks, re-installing archlinux-keyring worked.

Re: [SOLVED] Pacman refuses to upgrade due to missing key

For future self and possibly others: Check your system clock. I forgot that I removed the CMOS battery so my time reset to ~2002. The keys were obviously invalid at that time, which is why you get the error. I had to not only set the correct time but also reboot, then it worked.

(oh and it would be nice if pacstrap could just casually check time from some internet server and report if it is years off)

Re: [SOLVED] Pacman refuses to upgrade due to missing key

I think the best solution for this case is

pacman -Sy archlinux-keyring
pacman -Su

Some people may say that the first command is a partial upgrade, but archlinux-keyring could be an exception especially considering that a full update follows right after. Why -Sy and not -S? To make sure you have the latest keys.
