error: failed retrieving file 'msys.db' (Solved on x86_64 Windows 10)

[rdthree]

pacman.conf sets Architecture = auto and it appears that auto uses uname -m which results in 86_64.
the msys mirror paths use x86_64 not 86_64
as a result I manually changed pacman.conf to say Architecture = x86_64. This might be useful if posted somewhere for others having similar problems.

This was one example from the debug result of pacman -Syuv --debug
debug: response code: 404 error: failed retrieving file 'msys.db' from repo.msys2.org : The requested URL returned error: 404 debug: url: https://sourceforge.net/projects/msys2/files/REPOS/MSYS2/86_64/msys.db
it should instead direct to:
https://sourceforge.net/projects/msys2/files/REPOS/MSYS2/86_64/msys.db

Thank you. This fixed the same issue for me.

For me $ uname -m gives x86_64, so I don't know what your problem is.

I have the same issue. uname -m gives 86_64 with msys2-runtime version 3.0.1.

[StarWolf3000]

There is no msys2-runtime with version 3.0.1. The latest is 2.11.2-1. See this comment: #1578 (comment)

Right. That's from GfW.

So, if you want Git for Windows and don't care about pacman, use the Git for Windows setup, otherwise install MSYS2 and then install the git package with pacman to make sure, everything is working as intended.
For some reason, the standalone setup is not in line with the release in MSYS2, breaking things afterwards.

the same thing just happened when updating my other laptop. changing the Architecture line on pacman.conf was a pretty easy fix. Almost reminded of the good ol' days when all I used was Arch Linux.

As stated, this is not an issue with the official repositories of MSYS2 and their mirrors. Report it at https://github.com/git-for-windows/msys2-runtime and https://github.com/git-for-windows/MSYS2-packages.

sounds good, those repo's have no issues section so I just made pull requests.

New MSYS2 user here - this is still happening.

In case error is: 'msys.db' from downloads.sourceforge.net : The requested URL returned error: 404, (got that on 2022-June):

1. Sourceforge server is empty now:
   
   

2. I have fixed this by removing Server = https://downloads.sourceforge.net/project/msys2/REPOS/MSYS2/$arch/ line from \etc\pacman.d\mirrorlist.msys:

was:

fixed:

Got this idea by examining pacman log file, found inside \var\log\pacman.log: such line appeared there: [ALPM] warning: /etc/pacman.d/mirrorlist.msys installed as /etc/pacman.d/mirrorlist.msys.pacnew.

I hope that helps!
