Hello,

I am building a software image and it fails when fetching a repository form GitLab.  https://github.com/ajstarks/openvg

Initially I was using git:// protocol to fetch the files but due to the GItLab ended support of git:// I am using https:// protocol. I am getting following error. Any help is appreciated. Thank you.

Otherwise you should retry the download and/or check with upstream to determine if the file has become corrupted or otherwise unexpectedly modified.

Hi Rashmi,

You only need to add ;protocol=https to your SRC_URI which starts with git://.

git:// in SRC_URI is NOT the protocol used to download the sources, it is the way Bitbake knows which fetcher to use (in that case, the git fetcher). If you replace it with http, it's going to be the HTTP fetcher, which uses curl. It is not what you want to use for git repos.

c.f. https://docs.yoctoproject.org/bitbake/bitbake-user-manual/bitbake-user-manual-fetching.html#git-fetcher-git

Hope this helps,
Cheers,
Quentin
