I installed Mailpile onto Ubuntu 16.04 using the Adding Repository directions.
Shortly after installation, ubuntu started kicking out this error:
An error occurred, please run Package Manager from the right-click menu or apt-get in a terminal to see what is wrong. The error message was: 'Error: Opening the cache (E:Opening /etc/apt/sources.list.d/000-mailpile.list - ifstream::ifstream (13: Permission denied), E:The list of sources cound not be read.)'. This usually means that your installed packages have unmet dependencies.
Does anyone know how to fix what ever is wrong?
