Thanks for filing this bug in Ubuntu. Indeed the complaint was that bind couldn't write to /var/cache/bind. Do you happen to know what it was set to? That would help in debugging how it reached that state.
The attached logs unfortunately do not have more information about that, only the failure after the permission was incorrect already. I'll mark this bug as incomplete for that reason, as we have no way to reproduce the issue. If you are able to get more information about this, or show a way to reproduce the problem, then please comment here and switch the bug status back to "new". ** Changed in: bind9 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Server, which is subscribed to bind9 in Ubuntu. https://bugs.launchpad.net/bugs/1833812 Title: package bind9 1:9.11.4+dfsg-3ubuntu5.4 failed to install/upgrade: installed bind9 package post-installation script subprocess returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bind9/+bug/1833812/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
