Resolve "Cannot download packages whilst offline" issue in Deja-Dup backup software
If you got the error message "Cannot download packages whilst offline" but your internet connection is active, this is probably because you've managed the network configuration yourself and the network manager is reporting an offline status even if it's not correct. To fix this issue, simply edit the file /etc/NetworkManager/NetworkManager.conf and change the following configuration to be inline with: [ifupdown] managed=true Then restart the Network Manager : sudo service NetworkManager restart #1
