That repo will give you R and key R packages like Matrix lme4.  (And you
chose to ignore this repo by compiling R yourself ...).

Not really: I installed r-base and r-base-dev from "My repo", but ignored

deb http://ppa.launchpad.net/marutter/c2d4u3.5/ubuntu bionic main
# deb-src http://ppa.launchpad.net/marutter/c2d4u3.5/ubuntu bionic main

because I thought it was easier to handle the rest via install.packages()

I was wrong. After reinstalling all extra packages via apt and 
"c2d4u3.5", all my problems have vanished (or been swept under the 
carpet;), no segfaults. Many thanks!

Additional package repos then build on top of this one and give you several
_thousand_ r-cran-* binary packages prebuilt.
