VSTS build agent failed with get sources: Permission denied

Question

I have seen a couple of posts, but it did not help me. I have created around 10 Linux machines in Azure and added them to agent pools.

First, the build succeeded, but when I queued the build again, it failed at get sources with the below error.

My build definition was configured:

• clean: true
• clean options: sources

Error:

Answer 1

Based on the logs, it seems delete for the duilddir/support-files directory is not allowed (you can also check the permission by referring to the post Why can't I delete a file where I have group write permissions on?).

Please set the permission enable to delete under your agent's work folder.
