Hi Ashutosh, Thanks for reporting this, but it appears to be an issue with your openssh configuration file, specifically:
sshd[4592]: /etc/ssh/sshd_config line 89: Bad SSH2 mac spec 'hmac- sha2-512,hmac-sha2-256,hmac-ripemd160'. Please check your configuration file to make sure it's OK. ** Changed in: openssh (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1806253 Title: package openssh-server 1:7.6p1-4ubuntu0.1 failed to install/upgrade: installed openssh-server package post-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1806253/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
