does anyone know (I assume the devs do) if running the command below would kill my install of UM in the future, or now that UM is an official flavour of Ubuntu, will it upgrade to the next version of Ubuntu Mate and not the next version of Ubuntu wiping my UM install?.
sudo do-release-upgrade
I ask because I would like to add this command to the Update Guide if it won’t kill Ubuntu Mate!.
Never tested it. Perhaps some one could test/document upgrading from 14.10 to 15.04. Use a VM for testing. This is bound to come up and I don’t have the time to test it
Is it technically possible to trick Ubuntu into thinking that 15.04b2, or a build in between 15.04b2 and 15.04 final, is 15.04 final? If it is, I would have a go at testing the 14.10 - 15.04 upgrade.
Good news peeps, I tried the command out on Ubuntu Mate 14.04 with a base install and full updates and it worked, I am typing from UM 14.10 now and it did a full upgrade to Mate no problem!. (Not a sign of Unity praise be!)
I will mark this as solved if you have no objections Wimpy and include the command in the update guide!.
PLEASE NOTE THAT THIS WAS DONE USING 14.04 TO 14.10!.
Yesterday upgraded successfully from Ubuntu Mate 14.10 to Ubuntu Mate 15.04 on two computers - Thinkpad T530i and Thinkcenter M83. I did it with sudo do-release-upgrade -d
No any problems seen so far.
Please note that mentioned command will upgrade to Development Branch of Ubuntu Vivid (which is close to a stable release very soon).
