Comment 3 for bug 809075

Thank you very much in advance for your help on this issues~~~

>>>>Open a terminal (ctrl-alt-t) end execute these three commands:

sudo rm -rf /var/lib/apt/lists
sudo mkdir /var/lib/apt/lists
sudo mkdir /var/lib/apt/lists/partial ≳>>>

When I execute above, I got following issues.

´rm: invalid option --´/´
then I went into the file manager and tried to delete the lists folder and got error msg:
lists: Unable to trash file: Permission denied. I could not change permission to read & write. It goes back to read only for group and others.

files inside lists folder:
