@avenda Likely a problem with your network. Some googling suggests maybe you have a proxy or DNS issue.

No proxy o DNS issue behind. I have the stable branch (proton_5.0) in othe folder and i have no issue building proton. i will try to destroy the VM and do a make install again. ill let you know guys

Solved!: vagrant destroy and make install again solve the problem and now i can build successfully. Thanks!
