Signature not found

Hello Artix Linux Community,

I'm hoping for some assistance or insight regarding an issue I'm encountering while trying to run sudo pacman -Syyu on my Artix x86_64 system.

For several days now, pacman -Syyu has consistently failed during the database synchronization step. My verbose curl logs indicate a recurring 404 Not Found error specifically for the repository database signature files (e.g., system.db.sig, world.db.sig).

Here's a summary of my observations and troubleshooting steps thus far:

    The Problem: pacman -Syyu fails with:

        curl: (22) The requested URL returned error: 404

        error: could not rename /var/lib/pacman/sync/.../system.db.sig.part to .../system.db.sig (No such file or directory)

        This occurs for system.db.sig, world.db.sig, and likely other repository .sig files.

    Mirrors Tested (all showing the same .db.sig 404):

        https://mirror.clarkson.edu/artix-linux/repos/$repo/os/$arch

        https://mirrors.dotsrc.org/artix-linux/repos/$repo/os/$arch

        https://mirrors.aliyun.com/artix-linux/repos/$repo/os/$arch

        (Confirmed correct /repos/ path for these in mirrorlist).

    Key Debugging Findings:

        The main database files (.db) themselves download successfully (e.g., system.db, world.db return HTTP/2 200 responses and complete transfer). It's only the associated .sig files that return 404.

        My general internet connectivity is robust (ping to 1.1.1.1 and dig google.com work).

        DNS resolution for all tested mirrors is working correctly.

        SSL certificate verification for connections to mirrors is successful.

        wget -v tests for individual .db files and some .pkg.tar.zst.sig files were successful.

        XferCommand = /usr/bin/curl -L -C - -f -o %o %u --retry 5 --retry-max-time 30 --connect-timeout 10 -v has been set in pacman.conf to capture verbose output, which consistently shows the 404 for .db.sig files.

        Attempted IPv6 disablement via sysctl (as sometimes IPv6 can cause issues), but the problem (404 for sig files) persists regardless.

    My Question to the Community:

        Has anyone else encountered this consistent 404 error for the *.db.sig files on these or other Artix mirrors recently?

        Are these specific .db.sig files expected to be present at these mirror locations, or could there be an issue with how they are being synced from the upstream source?

        Could you please advise if there's a specific mirror known to be fully synchronized and complete with all necessary signature files for a pacman -Syyu?

I'm happy to provide full pacman_debug_*.log files if that would be helpful for further investigation.

Thank you very much for your time, your hard work on Artix, and any assistance you can offer!

Are these specific .db.sig files expected to be present at these mirror locations,
No. Something else is at play. Packages have .sig files, the database files don't.

Post your /etc/pacman.conf and also add --debug to your -Syu command and post that.

Re: Signature not found

I don't think the missing .sig files are your problem entirely.
To be clearer than I was the repo database files can be signed. They just never are that I've seen.
Code: [Select]
SigLevel    = Required DatabaseOptional
Is saying packages must be signed, optional for the databases.

The pacman debug output is first just telling you it couldn't find the optional db.sig.
I just checked I get the same output up to a point. But my update completes.

Them labeling it an 'error' doesn't help. It's not strictly an error if something optional isn't there imho .

What I don't have in my output is any similar to your

error: could not rename /var/lib/pacman/sync/download-fCAJlh/system.db.sig.part to /var/lib/pacman/sync/download-fCAJlh/system.db.sig (No such file or directory)

Could you try commenting out your custom XferCommand = and see what happens.

Also post all of the output , including the command used, using a link to some sort of pastebin or attachment etc.

Edit:
Also
Code: [Select]
ls -al /var/lib/pacman/sync
please.

I understand, thanks for looking into it.

When commented out the xferCommand it just shows time out despite me finding the best ten mirrors using rankmirrors.

When XferCommand = /usr/bin/curl -4 -L -C - -f -o %o %u --connect-timeout 20 --retry 3 --retry-max-time 60
is uncommented, curl instead of Pacman's internal downloader is used, it forces IPv4 (-4) to avoid IPv6 issues, enables download resuming (-C -), adds retry logic if the mirror stalls or fails and times out cleanly if the server is too slow.

Results for both attempts are attached here with this post.

As for the package database, it lists as follows:

Code: [Select]
$ ls -al /var/lib/pacman/sync
total 6528

I don't know ?

Things that spring to mind that I think I'd try.
Connecting to the internet via another method like via a mobile (which isn't on the the router wifi) and seeing if you have the same issue.
Manually downloading pacman-static and installing it with pacman -U then seeing if the same happens.
Disabling ipv6 entirely if you suspect issues.

If I think of any thing else I'll add it
