Ubuntu
software-center package

package will not install non pae processor cannot install new software package system broken clicking repair fails

Asked by Mike Shock

I have Ubuntu 12.04 on a Dell Latitude D400 installed using command forcepae == forcepae and the OS works fine until update. After update the system indicates that my package system is broken and the issue is related to having a non-PAE processor in use. Is there any way to reject that particular package and fix my package system? I cannot access the Ubuntu Software Center without it asking to repair the package system, which due to my non PAE processor, the unmet dependency cannot be met. Any way around this so I can install my utilities like I had on Ubuntu 10.04LTS?

Maybe it's because you were originally using a non-PAE kernel and after upgrading, you are booting into a PAE kernel that your PC's CPU cannot handle.

I suggest trying the following installation instructions instead, after backing up all your data to external storage:

https://help.ubuntu.com/community/9w#Ubuntu_14.04_LTS_text_non-pae_.27Trusty-npae124-text-9w.iso.27_and_.27obi_Trusty-nonpae-txt5-9w.iso.27

You can test for the PAE flag with the following command

grep --color pae /proc/cpuinfo

If it's a kernel install giving you issues you can apt-pin to make it not upgrade the kernel.

What is the output of:

sudo apt-get update; sudo apt-get upgrade

Thanks

There should not be any influence on the package management system whether the processor has pae capabilities or not.
I assume that there was some fault during a previous update action that has brought the package management system into an inconsistent state.

My recommendation is to follow steps 1 to 6 in https://help.ubuntu.com/community/PackageManagerTroubleshootingProcedure

Can you help with this problem?
