[SOLVED]Pacman stopped finding updates even when trying another mirror

Turtyo · 2023-10-17 10:13:22

Hello !

Since 3 days, pacman stopped finding updates after running sudo pacman -Syu. I also tried sudo pacman -Syyuu just in case but same result. Here is the actual output:

sudo pacman -Syyuu

I thought it was a problem of mirror, so I used reflector with:

 reflector -c france

To get up to date mirrors that I would copy into /etc/pacman.d/mirrorlist, but this doesn't change the result (I saw reflector can directly write in the mirrorlist, I should probably do that instead of a copy).

The problem started 3 days ago, after I tried to do an update as usual, and I got an error message (that I can't find in /var/log/pacman.log), mentioning an RPC connection fail. Also, even though pacman doesn't find any update to do, I could still install reflector from the extra repository even after the error appeared.

I saw that using a VPN could be the cause of the RPC connection fail mentioned above, but I do not use one so the error doesn't come from here.

Thank you in advance for any help provided !

Please pass the full log of the error.
Also try to:

mv /var/lib/pacman/sync{,.bkp} && pacman -Syu

Notably the output of "pacman --debug -Syu", the symptoms sound like you configured https://wiki.archlinux.org/title/Arch_L … cific_date

For some unknown reason it seems to have fixed itself. I kept trying different servers using:

 reflector - c france -p https

I think using https may have helped ?

And now I have updates since yesterday. For the RPC error I mentionned, I do not find it in pacman's log. Here is the output of "pacman --debug -Syu":

Even if I seem to be able to update now, there are still some errors in the output of the debug it seems like.

The only "errors" I see in the debug output is the missing database signatures which are
1. optional
2. afaict still not a thing, https://wiki.archlinux.org/title/Pacman … ing_pacman

Edit: since things work now, the debug log doesn't tell much about the (previous) problem but I don't think that _limiting_ the mirrors to https helped here.
I'd not geo-restrict the mirrors though, but go strictly by performance.

Yeah, this is what I saw too, guess I should put try to put to look into this database signature. Anyway, I will mark this as solved, even if the reason as to why is not very clear
Thank you for taking the time to respond you two !
