View Full Version : Upgrade Ubuntu 16.04 to 18.04 *Offline* (Using private APT mirror)

April 18th, 2018, 12:28 PM
The release of 18.04 LTS is coming soon, and I would like to update my offline Ubuntu VMs (all of them running 16.04).
I have offline APT repository, which I created using apt-mirror tool.
All of the VMs sharing single private network with the private APT repository, without any connection to the WWW.

After I'll bring all of the 18.04 repository packages to my offline APT repository, what steps should I take in order to update my 16.04 VMs?
I would like to avoid data & configuration loss in my VMs off course.

You follow the usual instruction, so first of all you change your sources.list to reflect the new version then you apt-get update & apt-get dist-upgrade and then you just go with the flow...
