Possible to upgrade the ubuntu of my lxc container?

[ytwytw]

Hi

I am using Proxmox 4.1 and I have some LXC containers running with Ubuntu 14.04

Is it possible to upgrade those containers from 14.04 to 16.04?

Do-Release-upgrade does not help in this case

Please advise

Thanks,

Hi,

generell it is no problem to upgrade a Linux to a newer version.
But be careful and make a Backup before you upgrade your CT.

Hello,


We are using 4.2 and are trying to upgrade our container from Ubuntu 14 to 16.
We have had no success at all since the container keeps on saying :

root@API-Server:/# do-release-upgrade -d
Checking for a new Ubuntu release
No new release found​

Of course we have been doing the usual and expected :

apt-get update
apt-get install update-manager-core
do-release-upgrade

or
do-release-upgrade -d

​

Absolutely no luck at all and always the same message :

Checking for a new Ubuntu release
No new release found​

Any idea ?



root@API-Server:/# lsb_release -a
No LSB modules are available.
Distributor ID:Ubuntu
Description:Ubuntu 14.04.4 LTS

At the end of Day,

I just create a new LXC and manually migrate over (5 containers, not too bad to do manually)

But it would be great to know if there is automated way to do it

and you can always manually change the sources.list from trusty to xenial and the do a apt-get update && apt-get dist-upgrade
