Opening /etc/apt/sources.list.d/proot.list - ifstream::ifstream (13: Permission denied)'

Thank you for taking the time to report this issue and helping to make Ubuntu better. Examining the information you have given us, this does not appear to be a bug report so we are closing it and converting it to a question in the support tracker. We appreciate the difficulties you are facing, but it would make more sense to raise problems you are having in the support tracker at https://answers.launchpad.net/ubuntu if you are uncertain if they are bugs. For help on reporting bugs, see https://help.ubuntu.com/community/ReportingBugs#When%20not%20to%20file%20a%20bug.

Thanks Brian,

This is my first time reporting anything to Ubuntu the error message I
got specifically said and I quote 'Please report this bug against the
'update-manager' package and include the following error message:..". It
described it as a bug as I reported it as one. My apologies if you do
not consider it a bug.

I desperately need help. I have tried in terminal to use apt-get update
and upgrade but I think my source list has been corrupted as I cannot
even read my source list (see below). Do you have any idea how I can fix
this

udunna@udunna-work --> apt-get update
E: Opening /etc/apt/sources.list.d/proot.list - ifstream::ifstream (13:
Permission denied)
E: The list of sources could not be read.

This is apparently an ongoing issue/erorr/bug in precise. see:

https://bugs.launchpad.net/ubuntu/+source/apt/+bug/746625

It appears that after installing certain packages, software center silently crashes. Even apt-get update and upgrade in terminal also fail. Not sure why Ubuntu does not see this as a serious issue.

I just resorted to removing the proot, the package I tried to install from my source.list.d. (see http://askubuntu.com/questions/120621/how-to-fix-duplicate-sources-list-entry). At least my software center is back and I can run update/upgrades again. I will worry about proot later.

Apparently the access rights settings of the file /etc/apt/sources.list.d/proot.list were wrong.

Running the commands

ls -l /etc/apt/sources.list
ls -l /etc/apt/sources.list.d
cat -n /etc/apt/sources.list.d/proot.list

probably would have revealed what to do to correct this.
