[R-SIG-Mac] damned Catalina

[bruno apolloni]

Dear All

among disasters of the new operating system Catalina, this one concerns R.

Trying to install “regtools"  the answer by Crane R consolle is 

unable to access index for repository https://cran.stat.unipd.it/bin/macosx/el-capitan/contrib/3.6 <https://cran.stat.unipd.it/bin/macosx/el-capitan/contrib/3.6>

The same  for “devtools”. This happens on my Mac with Catalina OS. The same installation on same Crane R but  on a laptop of colleauge of mine endowed with previous OS (el captain) succeeds without any problem.

Any remedy to suggest?

Thanks a lot

Bruno
