Ubuntu dependency issue while upgrading (linux-headers-generic (= but is to be installed)


I faced an error while I ran the apt-get upgrade command on the Ubuntu 12.04 LTS server for fixing the Glibc vulnerability. The Exact error is

linux-header: depends on linux-headers-generic (= but is to be installed.

Below is the steps for fixing the issue. First check the header packages installed using the command

apt-get --get-selections |grep -i header

Then remove the below packages using the dpkg commands as below.

sudo dpkg -r linux-image-generic-pae
sudo dpkg -r linux-headers-generic-pae
sudo dpkg -r linux-generic-pae

Now run the below commands to upgrade

sudo apt-get -f install
sudo apt-get upgrade

This will installl the required packages and will replace the headers with new one and will resolve the dependency issues.

Thanks and Regards
