DNU restore failed, https GET timed out

Question

I'm having some problems with restoring nuget packages using 'dnu restore'.

root@esomimx6s:~/TestASP5/src/TestASP5# dnu -v restore
Could not determine OS version information. Defaulting to the empty string.

When I issue the same commands on a BeagleBone Black (in the same LAN) all goes well. What else can I try to further debug what's going wrong?

Answer 1

Had the same issue as described on Fedora 23. The error messages are indeed misleading and running the sync using mozroots fixes the issue.

mono /usr/lib/mono/4.5/mozroots.exe --import --sync

The output from running that is:

Importing certificates into user store...
140 new root certificates were added to your trust store.
Import process completed.

p/s: would have placed this as a comment but I don't have enough reputation.

Answer 2

I found the solution to my problem. I'm aware that the HTTPS GET request needs some amount of certificates to be installed. But because the errors do not state that authentication was the problem, I was assuming this was not the issue. However, it was indeed the root of my problem...

If fixed it by running:

mono /usr/lib/mono/4.5/certmgr.exe -ssl -m https://go.microsoft.com
mono /usr/lib/mono/4.5/certmgr.exe -ssl -m https://nuget.org
mono /usr/lib/mono/4.5/certmgr.exe -ssl -m https://api.nuget.org
mono /usr/lib/mono/4.5/mozroots.exe --import --sync
