I was getting the error “Ignoring file ‘parrot.list.dpkg-dist’ in directory /etc/apt/sources.list.d/’ because it has an invalid file extension” I learned too late that this was not an error but just a warning message 'parrot. I accidentally deleted the package list file list.dpkg-dist via terminal and I can’t get it back, please help. Thanks in advance.
You don’t really need it unless you want to use very old Parrot branches which are not supported anymore. AFAIK, the file dpkg-dist are backup files for old mirror settings.
