Thank you. Being new to Ubuntu and Linux, I was unaware of the dire implications of changes in the sources.list file. All instances of ‘trusty’ have been changed back to ‘bionics’. It was included as a possible reason for my inability to compile and link R and C++; so, from a new-person perspective, it was useful.</div><div class=""><br class=""></div><div class="">2.<span class="Apple-tab-span" style="white-space:pre"> </span>Dirk Eddelbuettel. The ‘litmus’ test that you suggested worked. Thank you. Glad to know that it will be supported on Windows10 (and MacOS, too, I assume). Now, also, I know about the r-sig-debian list, which is where I will now be able to direct relevant questions.</div><div class=""><br class=""></div><div class="">3.<span class="Apple-tab-span" style="white-space:pre"> </span>Ralf Stubner.
