I am running Ubuntu 16.04 and when trying to unpack linux-headers-4.4.0-66-generic apt hangs indefinitely. I terminated the apt process, removed the stale lock files, and ran:

sudo apt-get clean
sudo dpkg --configure -a

and the result is:

dpkg: dependency problems prevent configuration of linux-generic:
linux-generic depends on linux-headers-generic (=;
Version of linux-headers-generic on system is

dpkg: error processing package linux-generic (--configure):
dependency problems - leaving unconfigured
Errors were encountered while processing:

I then ran:

sudo apt-get update
sudo apt-get ugrade

with the following result:

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
linux-generic : Depends: linux-headers-generic (= but is installed
E: Unmet dependencies. Try using -f.

Running apt-get -f install starts the cycle over again and I can't get these issues with apt hanging and linux-generic installing properly.

Any ideas?

  • sudo apt install linux-headers-4.4.0-66-generic writes the result in your post? – BlueManCZ Mar 8 '17 at 22:33
  • @BlueManCZ Gave it a try -- this is what I got: $ sudo apt install linux-headers-4.4.0-66-generic Reading package lists... Done Building dependency tree Reading state information... Done linux-headers-4.4.0-66-generic is already the newest version (4.4.0-66.87). linux-headers-4.4.0-66-generic set to manually installed. 0 upgraded, 0 newly installed, 0 to remove and 23 not upgraded. – Glen MacLachlan Mar 9 '17 at 1:39
