I have tried this with many update sites and I got the same error, so what is this?if someone interested in the full log I can post it.

Thanks

Answer 1

I also had the same problem, What I did was I had previously set a proxy address so when I went to a network that required no proxy, I got that error.

I solved the problem by

1. Preferences
2. Network connection
3. Then set network provider to Direct.

Answer 2

I got the same issue and by following various options mentioned above I could able to find a solution for ProvisionException:

Solution: If you are behind proxy, set the network option to "manual" and provide the proxy host, port. If the proxy needs authentication provide the username and password.

I am assuming if you are not behind proxy you can use "Direct" option in network setting.
