Setting up snapd (2.14.2~16.04) ...

I had to kill dpkg process. Then after apt-get update dpkg shows message:

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. 
gondy@***:~$ sudo dpkg --configure -a
Setting up snapd (2.14.2~16.04) ...

And it hangs again. What should I do? Do I need this package at all? I am running Ubuntu 16.04, upgraded from 14.04 LTS Server edition.

    The problem is still there in Ubuntu 18.04.

This is a known bug, it is already fixed in -proposed. You can wait until the fix makes it's way to stable, enable testing or use a workaround:

  1. start a rootshell with sudo -i
  2. run echo "bash -c 'service snapd.boot-ok start'" | at now + 4 min
  3. run apt install snapd (if it argues about canceled dpkg processes use dpkg --configure -a)
  4. wait for at least 4 minutes

Or just run sudo service snapd.boot-ok start from a different console after seeing Setting up snapd... on the first console.

    Thanks for answer. However, I have solved this by simply removing snapd package.. I dont need it.
