try to solve a pacman problem with rate-mirrors

[theotrst]

Hi,
I am on ALARM (Arch-asahi linux on M1), I recently encountered a problem after last update. I run

sudo pacman -Syu

but during the process, I had a problem of internet connection and the processes has been interrupted. I tried it later and I get an error saying that it was impossible to download a package as the operation was too slow, and to synchronize all databases, due to an error in download library (I translate because it was in italian, below the full message).

I tried to search out to solve this, I added "--disable-download-timeout" to the process, but it didn't work, I even uncommented a number of mirrors in /etc/pacman.d/mirrorlist, but I got always get the same error.

Then I found rate-mirrors package (from ArchLinuxARM repository), and I thought, this could be a solution, but I am not sure how I should proceed.

Any advice is welcome!
thanks

hi @theotrst , to be honest I have no idea :/ but to reply with something, here is an answer from ChatGPT 5.4 Pro (the deepest reasoning I have access to at the moment):

From the log you pasted, the immediate problem is not really the interrupted update itself; it is that pacman cannot fetch the asahi-alarm sync database. rate-mirrors can rank Arch Linux ARM mirrors with rate-mirrors archarm, and it also has a stdin mode for custom mirror lists, but it only helps when there are multiple mirrors to choose from. The current Asahi ALARM instructions configure [asahi-alarm] via /etc/pacman.d/mirrorlist.asahi-alarm, and that file points to a single GitHub Releases base URL, so rate-mirrors is unlikely to fix this specific asahi-alarm.db timeout. ([GitHub])

--disable-download-timeout is a valid pacman option, but pacman documents it as disabling the default low-speed limit/timeout, mainly for proxy or security-gateway style download issues. If GitHub itself is slow or unreliable from your network, it may still not solve the underlying problem. ([Arch Manual Pages])

So I would first check /etc/pacman.d/mirrorlist.asahi-alarm. If it still points at GitHub, the useful next steps are to try again from another network, try different DNS or a VPN, or ask the Asahi ALARM maintainers whether they have an alternate mirror. Their README even notes that some systems may need 1.1.1.1 as DNS. ([GitHub])

If you also want to optimize the normal Arch Linux ARM repos, then rate-mirrors archarm is the relevant command. Arch Linux ARM’s default mirror setup uses mirror.archlinuxarm.org, which GeoIP-redirects to nearby official mirrors, so reranking that list can still help for the regular alarm side of the system. It just will not change the separate asahi-alarm GitHub-backed repo. ([Arch Linux ARM])

export TMPFILE="$(mktemp)"
rate-mirrors --save="$TMPFILE" archarm \
  && sudo cp /etc/pacman.d/mirrorlist /etc/pacman.d/mirrorlist.backup \
  && sudo cp "$TMPFILE" /etc/pacman.d/mirrorlist
sudo pacman -Syyu

thanks! I'll try to figure out! and let you know in case.
