Now, this is my first time posting and I don’t know if this is the correct place, so please be gentle.
Recently I have been having problems updating my system due to signature check failures. I has also been preventing me from installing new software with pacman. When I checked the archlinux-keyring version provided by the mirrors vs. what is in archlinux packages (Arch Linux - archlinux-keyring 20240609-1 (any)), the one in arch linux packages is newer than the one available in manjaro core.
My question is probably, is this a known issue and is it just me or are there some wider problems with this? Is the keyring really older than it should in the core database?
Seriously, don’t. Never attempt to change anything under /usr unless you absolutely know what you’re doing.
I cannot tell you why this happened, but several of us have been bitten by this as well a few updates ago, while others were not.
I myself had key ring problems as well, and this was after I had refreshed my mirrors, which suggests that it must have been a problem at the mirrors, and strangely enough, one that should not have happened after refreshing the mirror list.
Either way, the solution is a lot easier than how you did it…
An update for archlinux-keyring to 20240609-1 has just popped up, so I guess either your problem has been silently solved or a Manjaro maintainer has noticed it too. Or maybe it was just a coincidence?
