It seems that none of my two snappy systems can access the Internet. When I run 'snappy list -u' I get the following error message:
Get https://system-image.ubuntu.com//ubuntu-core/15.04/stable/generic_amd64/index.json: dial tcp http://188.8.131.52/:443: i/o timeout
The above I get from a virtual snappy installation on VirtualBox. I also get a similar error from a snappy 15.04 stable (running from SD card) on a BeagleBone Black. The board is connected to LAN (because I can ssh to it from my desktop) but apparently it does not have Internet (pinging www.google.com, it says 0 packets received).
The BeagleBone Black is a new installation, but I am sure that I had Internet on the virtual machine before.
Does anybody else have this problem, or am I doing something wrong?
