Question

Upgrading server from Ubuntu 14.10 to 15.04?

Hi,

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, Benjamin

For anyone coming to this these days, this won’t be possible without modifying your apt sources.list since 15.04 (as well as 15.10) is End of Life.

I tried to upgrade using the steps suggested by the mod. My current installation is Ubuntu 14.x, and when I started the upgrade to 15.04, among the list of removed packages was mariadb and phpmyadmin. Is mariadb not packaged in 15.04? And if it is removed, won’t that screw up my databases?

I added the new repositories but do_release_upgrade still fails to find a new release.
