Arch Linux: pacman – error “HTTP server doesn’t seem to support byte ranges”

By | 05/30/2022

During system upgrade with pacman -Syu, I got internet disruption, and on the next upgrade I got the error from pacman.

It sounds like “HTTP server doesn’t seem to support byte ranges. Cannot resume“:

==> Retrieving sources...

Actually, we can see that there is a problem with the Clightd/archive/5.6.tar.gz file, so let’s try to find it on your system, where it must be saved in a cache directory:

find /home/ -name clightd-5.6.tar.gz*

Aha, here it is!

Pay attention to the .part extension on the end of the file’s name – it just wasn’t fully downloaded.

So, to solve the issue, just clean up your local cache:

yay -Scc
Cache directory: /var/cache/pacman/pkg/
:: Do you want to remove ALL files from cache? [y/N] y
removing all files from cache...
Database directory: /var/lib/pacman/
:: Do you want to remove unused repositories? [Y/n]
removing unused sync repositories...
Build directory: /home/setevoy/.cache/yay
==> Do you want to remove ALL AUR packages from cache? [Y/n]
removing AUR packages from cache...

And run the upgrade again:

yay -Syu --noconfirm
