I've just attempted to run sudo apt-get dist-upgrade on my Ubuntu
box, but am getting the following error...
WARNING: The following packages cannot be authenticated!
librdbmspp php5-ioncube-loader sw-libboost-date-time1.49.0 sw-libboost-system1.49.0 sw-libboost-filesystem1.49.0 sw-libboost-program-options1.49.0 sw-libboost-regex1.49.0 sw-libboost-serialization1.49.0 sw-libpoco
I've tried running...
$ sudo apt-key update
$ sudo apt-get update
... as found in this question, but I'm still getting the error.
Can anyone help, please?
