[SOLVED] Pacman error: failed retrieving file 'core.db', 'extra.db' ..

Cbhihe · 2021-05-13 16:30:28

[OS: 5.12.2-arch1-1 - last update approx 1 day ago]

The error appeared out of the blue with no problematic install prior and no `*.pacnew` warning to resolve, just upon issuing my usual `sudo pacman -Syu`.

I did consult the forum and googled to find quite a few similar error messages all ending (as in my case) with "requested URL returned error: 404", but pertaining to the installation of single packages usually.
Also checked the Arch wiki, and tried this:

- replaced my usual mirrors in ` /etc/pacman.d/mirrorlist ` with first 10 at top of list in `https://archlinux.org/mirrors/status/` in section "Successfully Syncing Mirrors".
- then I did:

$ sudo pacman -Syyu
...   # same result for any mirror I select
$sudo pacman -Q | wc -l 
1774

Upon cursory inspection of installed package list, packages I recognize seem to correspond to the packages I explicitlly installed over the past 3 or 4 years since first boot. Nothing is obviously odd here.
Kinda stumped here, as this had never happened before. (

Post *exact* errors. Adding --debug is also a good idea.

Without debug, I get:

A reboot later and with the `--debug` switch, I get this which points to:

...
debug: sig path /var/lib/pacman/sync/extra.db.sig could not be opened
debug: missing optional signature
...

Is it possible your connection has been placed behind a captive portal?
What is the output of

curl -o /dev/null -v www.google.com

Cbhihe · 2021-05-13 17:15:44

I just added the 3 servers at the end of my list of 12 in `/etc/pacman.d/mirrorlist`:

Server = http://mirror.f4st.host/archlinux/
Server = https://mirror.f4st.host/archlinux/
Server = http://arch.jensgutermuth.de/
Server = https://mirror.chaoticum.net/arch/
Server = http://archlinux.thaller.ws/
Server = http://mirror.chaoticum.net/arch/
Server = https://archlinux.thaller.ws/
Server = https://mirror.pkgbuild.com/
Server = http://archlinux.uk.mirror.allworldit.com/archlinux/
Server = http://ftp.halifax.rwth-aachen.de/archlinux/
Server = https://arch.jensgutermuth.de/
Server = https://mirror.pseudoform.org/

## Worldwide
Server = http://mirrors.evowise.com/archlinux/$repo/os/$arch
Server = http://mirror.rackspace.com/archlinux/$repo/os/$arch
Server = https://mirror.rackspace.com/archlinux/$repo/os/$arch

then issued `# pacman -syyu` to force refresh of package DB. I did get a refresh after the first 12 servers returning same error as before. This updated my system to `5.12.3-arch1-1`.
I rebooted again and am back to square one: Error with `# pacman -syu` and ERROR followed by REFRESH with `# pacman -syyu`...

I am even more stumped.

BTW I use a torrified Firefox to navigate but any http(s) request from terminal exits normally (does not use tor).

The connection to google is fine, what about:

curl -o /dev/null -v http://mirror.f4st.host/archlinux/core/os/x86_64/core.db

Cbhihe · 2021-05-13 17:35:56

Corrected newly added server in Post #5 to full url path, e.g.: `Server = https://mirror.chaoticum.net/arch/` --->> `Server = https://mirror.chaoticum.net/arch/$repo/os/$arch`.

Everything seems to be back to normal as of 2 days ago. Don't know what was the initial issue as file signatures are optional and the addition from incomplete server urls is just a late copy/paste troubleshooting mistake of mine from 2 hours ago...

Sorry for the noise.
