[Ubuntu 16.04 LTS has reached the end of it's *standard* support life](https://fridge.ubuntu.com/2021/03/13/extended-security-maintenance-for-ubuntu-16-04-xenial-xerus-begins-april-30-2021/) thus is now off-topic here unless your question is specific to helping you move to a supported release of Ubuntu. Ubuntu 16.04 ESM support is available, but not on-topic here, see https://askubuntu.com/help/on-topic See also https://ubuntu.com/blog/ubuntu-16-04-lts-transitions-to-extended-security-maintenance-esm

Probably `sudo systemctl --failed` will return a lot of services with failed state. Did you fail to upgrade? Try `sudo apt install -f`. Are you trying to upgrade to something like 22.04?

The errors you see are startup failure message for various services (ufw = firewall, AppArmor is a security utility from the kernel and keymap is for your keyboard).

You are in tty mode, which suggest that your VM could not load th graphics driver. Since you are in tty, after logging in you could type dmesg, which should output errors encountered at boot.

As said before, Ubuntu 16.04 lts is in end of life, so you could fix the problems by using ubuntu 20.04 lts or 22.04 lts, since it's a more recent OS.

When using dmesg, did you see any errors?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
