Public bug reported: Fresh install of 16.04 in a virtual box VM from the "Desktop" ISO.
Tried to install docker but it hung during the install, relevant ps fax showed: 2033 pts/17 S+ 0:00 | \_ sudo apt install docker.io 2034 pts/17 S+ 0:00 | \_ apt install docker.io 5049 pts/1 Ss+ 0:00 | \_ /usr/bin/dpkg --status-fd 59 --configure bridge-utils:amd64 cgroupfs-mount:a 5118 pts/1 S+ 0:00 | \_ /bin/sh /var/lib/dpkg/info/docker.io.postinst configure 5172 pts/1 S+ 0:00 | \_ /bin/sh /usr/sbin/invoke-rc.d docker start 5208 pts/1 S+ 0:00 | \_ systemctl start docker.service 5209 pts/1 S+ 0:00 | \_ /bin/systemd-tty-ask-password-agent --watch Presumable it is trying to prompt for a password to start the service but that is not propagating to the UI. Killing 5208 and 5209 got me the not unexpected: Terminated invoke-rc.d: initscript docker, action "start" failed. dpkg: error processing package docker.io (--configure): subprocess installed post-installation script returned error exit status 143 Setting up liberror-perl (0.17-1.2) ...
