Ubuntu issue with 18.04 Bionic Beaver

Dear Dirk (other users and Dave)

PART 1
I finally was able to install R.3.5.1, however, I had to invoke the following

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E084DAB9

As this skin of Ubuntu 18.04 (Peppermint) does not seem to allow access to the bionic-cran35 repository unless this key is set and added to the system. 
This is odd - well for me anyway, as for other skins of Ubunto say 16.04 (Peppermint) I do not have to do this, though when I do sudo apt-get update it does complain bitterly about the key not being validated but continues?

Perhaps this would be a useful addition to the install notes on the R webpage.
Just a thought - unless I have done something really silly.

PART 2
On another related matter. (If I may beg for assistance)
I am a co-developer of an R package which is alas not open source - even I require a license key.
There is some setting which is stopping the Peppermint browser from allowing the RLM to access the session in R
See screenshot and also the page below for the way to install

If this is too much to ask for any ideas to work around then please ignore
thanks again
