[Solved]Installing AUR pkgs (Cemu and Wine-ge-custom) prepare() fails

This might be more of a package problem but I want to start getting to the bottom of these on the forums because the issue with two packages are similar. I have cemu and wine-ge-custom already installed and these issues started two day ago. When I tried to install cemu with manual (empty dir and  installing of AUR package same problems exist so it's not the yay problem.

The main thing I see is: fatal: transport 'file' not allowed but haven't find any issues what that entails.

If I try to install cemu package from AUR I get this kind of error:

==> Starting prepare()...
Cloning into '/home/christooss/aur/cemu/src/Cemu/dependencies/cubeb'...
fatal: transport 'file' not allowed
fatal: clone of 'file:///home/christooss/aur/cemu/src/cubeb' into submodule path '/home/christooss/aur/cemu/src/Cemu/dependencies/cubeb' failed

==> ERROR: A failure occurred in prepare().
    Aborting...

and similar one when updating/installing with wine-ge-custom:

==> Starting prepare()...

Thanks for the answers.

Re: [Solved]Installing AUR pkgs (Cemu and Wine-ge-custom) prepare() fails

I had this problem as well. This is due to the git 2.38.0-1 -> 2.38.1-1 update.

[ANNOUNCE] Git v2.38.1 and others - Junio C Hamano mentions:

Additionally, the value of `protocol.file.allow` is changed to be "user" by default.

So one method is to change that back:

$ git config --global protocol.file.allow always

I wonder if there's a less aggressive approach, specifically for Pacman or AUR Pacman wrappers.

Re: [Solved]Installing AUR pkgs (Cemu and Wine-ge-custom) prepare() fails

Why would you use --global?  That could be set --local just for the repo in question, and ideally it would be set upstream in the repo config.

EDIT: to clarify, using --global would be any easy way to not face this issue anymore.  But it only does so by excluding yourself from the set of people impacted by a packaging bug.  It should really be fixed in the package as the PKGBUILD should not rely on assumptions about the end user's system configuration: if it requires a specific configuration is should specify it.

It looks like this change will break every PKGBUILD using this: https://wiki.archlinux.org/title/VCS_pa … submodules

Does replacing

  git submodule update

with

  git submodule--helper update

help?

Re: [Solved]Installing AUR pkgs (Cemu and Wine-ge-custom) prepare() fails

@loqs: Yes,

git submodule--helper update

works. Time to update a whole bunch of PKGBUILDs--including appimagelauncher.

What does this command do that git submodule update doesn't?

git submodule uses /usr/lib/git-core/git-submodule which is the shell script https://github.com/git/git/blob/v2.38.1 … bmodule.sh which sets GIT_PROTOCOL_FROM_USER=0 [1] internally it uses git submodule--helper [2].

[1] https://github.com/git/git/blob/v2.38.1 … ule.sh#L29
[2] https://github.com/git/git/blob/v2.38.1 … le.sh#L338

Re: [Solved]Installing AUR pkgs (Cemu and Wine-ge-custom) prepare() fails

So it's like using an internal script to bypass a security measure?

I tried this inside a PKGBUILD, but the error stay the same:

git config protocol.file.allow always
(...)
git submodule update

For some reason the setting seems to only be respected when it is set in the global config.  No idea if this is a bug or intended.

Re: [Solved]Installing AUR pkgs (Cemu and Wine-ge-custom) prepare() fails

bit premature to just be switching all PKGBUILDS to use submodule--helper. seems more like an ugly workaround hack than a real fix to the issue.

the actual fix would need to be to pacman, as makepkg, part of pacman, is the thing that is doing this local cloning magic behind the scenes that no longer works. it was relying on git behavior that no longer exists.

edit: I've created a bug for this https://bugs.archlinux.org/task/76255 - note that as the bug report shows, this doesn't just affect aur packages. there are plenty of packages in the official arch repos with PKGBUILDs that rely on this submodule mechanism during builds. @yochananmarqos I think it is really unwise to start using internal git functionality that isn't even meant to be used, particularly if it is for the purpose of circumventing security measures. you have no guarantees as to the behavior of this internal non-exposed function. this whole problem started because the behavior of an actual-meant-to-be-used function changed, the solution is not to introduce even-more-likely-to-fail-in-the-future stuff imo

Re: [Solved]Installing AUR pkgs (Cemu and Wine-ge-custom) prepare() fails

You just have to replace

git submodule update ...

by

git -c protocol.file.allow=always submodule update ...

Re: [Solved]Installing AUR pkgs (Cemu and Wine-ge-custom) prepare() fails

I know this a year old post, but for anyone who is still stuck, my last method is to do

 git config --global protocol.file.allow always 

and then

 git config --system protocol.file.allow always

Also, I put the global parameter in there too since I cant do an exact replica of the situation at the moment. Arch is not letting me see how I solved it, as I too got this error.

Setting that option gobally/systemwide is not needed as benjarobin mentioned #13 .

For those needing more info : https://wiki.archlinux.org/title/VCS_pa … submodules
