Ubuntu 20.04 - Login freezes, local login to terminal works after ctrl-c

il flag
hcr

I have an Ubuntu 20.04 server that currently stucks during the login process. Remote SSH logins do not work at all. When I do a local login to a terminal, the login stucks as well, but resumes to a prompt after typing the password and then pressing ctrl-c. The problem seems not be related to my account, but also affects other users. .profile and .bashrc seem to be executed correctly. Also, login to services running on the server (like jupyterhub etc.) are possible without problems. By now, I checked dmesg and verified that /etc/passwd etc. are not corrupted. Is there any way to make the login process more verbose or any log file that explicitely logs things happening between typing the password and getting to the prompt?

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.
