(EDIT 21/10 A note to say that this was actually a package manager list error although it appears that the VB package - a fork - caused it. Thanks to all.)
Just joined as I am experiencing my first real issue with VB.
My Update Manager has four items to install one of which is virtualbox-ext-pack version 5.1.30-2. (From PPA costa... etc.)
When starting the update I get the response from the Update Manager i.e "E:dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem"
Running the suggested solution starts OK and runs through the License Agreement but then sticks at the end of item 10 (Miscellaneous) of said Agreement. From this point on the system does nothing.
I have tried various keyboard combinations to find the correct response to what I assume is the question regarding accepting the license terms but no luck and
as you will understand there is no visible option to 'tick'. Any help appreciated
