Thank you for your help, paride. Now, answering your questions: Yes, I am using last versions of Packer (1.8.0) and VirtualBox (6.1.32). Host is Windows 10. Ubuntu 20.04 works, but .1, .2, .3 and .4 update releases don't. By the way, the situation is worse in jammy daily builds because I can not even begin the unattended instalation (I have opened a question about this problem in Ubuntu forums https://ubuntuforums.org/showthread.php?t=2472899).
ens33 is in user-data file just because I copied a working example of autoinstall file. I can ssh login from the machine to itself. I have made some screenshots showing the output of commands you asked me for. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1964642 Title: Packer virtualbox ssh can't connect to unattended Ubuntu 20.04.1/2/3/4 but can connect to Ubuntu 20.4 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1964642/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
