    DMESG Inundated with Apparmor errors

    Hey all, I'm not very good with how Apparmor works, so I was hoping someone might help me solve this one. Two of my many LXC containers, ID 110 and ID 170 are resulting in an absolute spamming of DMESG as follows: Please see this pastebin. It was too much to post in a message here. Two...

    In Place Upgrade of Ubuntu 14.04 LXC Container to 18.04?

    Hi all, Is this advisable? The reason I ask is, I'm not sure I fully understand how the PVE frontend configures the containers network and other settings. 14.04 and 16.04 use ifup/down and are thus configured in /etc/network/interfaces, but 18.04 replaces ifup/down with netplan, which is...
