Looking at the logs, the error is: useradd: cannot lock /etc/group; try again later.
adduser: `/usr/sbin/useradd -d /var/run/sshd -g nogroup -s /usr/sbin/nologin -u 115 sshd' returned error code 10. Exiting. I suspect there is a stale /etc/group.lock file that you should remove (sudo rm /etc/group.lock). Please confirm that it allows to solve the situation.
