I could only resolve the ssh issue with killing the apt process, and restarted networking. This is a pretty bad issue imho. Upgrading packages through ssh should not disconnect the session, but even if it is, upgrading the systemd package should not result in not being able to log back in ever again!

The server has two active network adapters, both connected to the internet. One is used for outgoing internet traffic, the other for incoming. The incoming adapter lives on a public network segment (something like 88.236.133.104/29). I do have multiple servers within this segment. Typically, I update the server regularly, meaning: * ssh to the incoming adapter: ssh 88.236.133.108 * apt-get update * apt-get upgrade * apt-get dist-upgrade * apt-get clean * reboot It used to work ok. BUT: Today, "apt-get upgrade" seem to take really long when updating systemd. After a could of minutes, I realized that the ssh session became inactive. I couldn't type into it, I had to abort it via ~. . * ssh from the internet to the incoming adapter was not working anymore - ssh 88.236.133.108 * ssh via another server within the public network segment worked * ssh 88.236.133.106 -> ssh 88.236.133.108 * After running "netplan apply" everything was fine again Here my netplan configuration (I changed the ip addresses): network: version: 2 renderer: networkd ethernets: eno1: dhcp4: yes eno2: dhcp4: no addresses: [88.236.133.108/29] #gateway4: 88.236.133.105 routes: - to: 0.0.0.0/0 via: 88.236.133.105 table: 120 routing-policy: - from: 88.236.133.108/32 table: 120 - to: 88.236.133.108/32 table: 120 Unfortunately, I don't have the console output avalable anymore. Shall I provide additional info?
