repo sync fails on docker WSL2 from Windows

Hi,

So we are currently using a Virtualbox VM for Yocto, but the new possibility for use Docker with WSL2 could increase performance, so we are trying to compile our yocto meta-layer using the new docker method.

I am following this documentation : https://www.digi.com/resources/documentation/digidocs/embedded/dey/3.2/cc6ul/yocto_t_set-up-docker-windows

The first problem was that Docker Desktop shows a advice against using directly windows filesystem volumes because there is poor performance and no “inotify events”, see https://docs.docker.com/desktop/windows/wsl/

I had some “permissions denied” errors on bitbake, so I tried again using directly a docker linux volume (using docker desktop volume tab).
Do you recommend using a WSL2 volume instead of a Windows volume ? It seems to be the “best practice” on Docker Desktop doc.

The second problem is about repo sync. This command line :
dey@b53778495448: repo sync -j 4

gets this :

remote: Enumerating objects: 1, done.
remote: Counting objects: 100% (1/1), done.
remote: Total 1 (delta 0), reused 1 (delta 0), pack-reused 0
Unpacking objects: 100% (1/1), done.
Fetching: 100% (12/12), done in 13.178s
Garbage collecting: 100% (12/12), done in 0.070s
info: A new version of repo is available
warning: repo is not tracking a remote branch, so it will not receive updates
repo reset: error: Entry ‘command.py’ not uptodate. Cannot merge.
fatal: Could not reset index file to revision ‘v2.16.7^0’.

It looks like the docker image is not up to date and cannot update because on ‘command.py’, which is a repo file. Is this error important ? How to fix this ? I want to be sure that the version I build is up to date.

Have a good day,

Yes.

>The second problem is about repo sync. This command line Just tried it here and it seems to work. Are you sure you have network access?

try deleting everything in
and then do
Install the repo tool.

To install Digi Embedded Yocto, you need the repo tool. Download repo to a directory within your path and add execution permissions.

~$ sudo curl -o /usr/local/bin/repo http://commondatastorage.googleapis.com/git-repo-downloads/repo
~$ sudo chmod a+x /usr/local/bin/repo

~$ repo init -u https://github.com/digi-embedded/dey-manifest.git -b gatesgarth
~$ repo sync -j8 --no-repo-verify

Thanks, by reinstalling repo, deleting everything in /usr/local/dey-3.2, I managed to do this repo sync correctly :slight_smile:
