'E:Malformed line 44 in source list /etc/apt/sources.list (dist parse), E:The list of sources could not be read., E:The package lists or status file could not be parsed or opened.'

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your sources list is malformed. Could you please attach contents of file /etc/apt/sources.list to the report?

I am not able to attach the contents of life. Please let me know how I
can do it.

Thanks.

Open Terminal and run
cat /etc/apt/sources.list > sources.list

and add the file 'sources.list' from your home folder as an attachment to this report (or alternatively just open it in a text editor and copy-paste the contents here). Before attaching that file you might want to check that it contains no private information (e.g. a password for a private software repository).

Interesting. You seem to have repositories of Natty, Oneiric and Precise in your sources.list which is certain to cause some issues. I don't really have any idea what could've caused this. Have you done any distribution upgrades lately?

The only way to fix the broken sources.list is to manually replace your current sources.list with the default one and hope nothing breaks. To do that, please refer to the following Ask Ubuntu answer:

Thank you. The problem is sorted.
