[R] R installation Ubuntu 10.04 missing dependency

[Eric Berger]

Hi John,
Is the subject line of your question correct? Ubuntu 10.04?
If that is not a typo, that could be contributing to your problem. I
believe that the current stable release of Ubuntu is 18.04.
According to the following link ubuntu 10.04 was released almost 10 years
ago and was "retired" about 5 years ago.

HTH,
Eric
