An unresolvable problem occurred while initializing the package information.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

To help us resolving this issue, please run 'ls -l /etc/apt > apt.txt' (without the quote marks) and attach resulting apt.txt file to this bug report.

This looks like a incorrect proxy config and in addition incorrect permissions in /etc/apt/sources.list

Here is the error from the log:

platform compatibility". This is no longer the case, but they are
