About “repo sync”

[aaayushen]

Hello, I am a prospective graduate student from China who has had initial contact with OPTEE. However, I always encounter errors in the "repo sync -j10" step. I would like to ask if there is an error in the "fetch" step of the log and if it needs to be pulled again. The log is shown in the following figure. May I ask if there is a good solution? Thank you.

Our CI environments are using also using "repo sync" and they seem to be all green, so if there would have been an issue, then those should indicate failure as well. Could it be a firewall issue? I think I've heard that you need a VPN to be able to access some things outside China.

What you could try it so simply clone the failing ones using git directly, since after all that is what is done under the hood when running repo. So for example, just try to clone qemu.git

git clone git@github.com:qemu/qemu.git

And also try using https to see is that makes any difference

git clone https://github.com/qemu/qemu.git

If you have an issue with cloning any or both of those, then you likely have some connection / firewall issue and then it's guaranteed that repo also will fail.

Yes, it is indeed a problem with the network connection. At the same time, I have also used a VPN outside of China and turned off the firewall, but I still encounter network connection issues. My senior brother said that I need to try more.....
