Upgrading server from Ubuntu 14.10 to 15.04?
I am getting this notice when logging into my droplet:
New release ‘15.04’ available.
Run 'do-release-upgrade’ to upgrade to it.
However when I attempt “do-release-upgrade -d”, I get the warning “no valid mirror found” and do I want to update the sources.list file. Is this safe? or will updating the sources.list file effect the operation of my droplet in the future?
Any advice? Should I just avoid updating to the new release?
Thanks in advance,
