[R-sig-Debian] [FORGED] r-base is already the newest version (3.5.2-1bionic)

[Dirk Eddelbuettel]

Rolf,

I think it may help to read-up on dpkg and apt. Instead of 'whereis' do

  dpkg -l r-base-core

to see the content of that package.  Use

  apt-cache policy r-base-core

to see what the package cache says about where it gets the package from. And
so on.  Also

  type -p R
  which R

will tell where your system thinks R comes from. If you install R 3.5.2 you
should not see R 3.5.1.

These aren't really R issues. The package management system can be pure
source of joy. Something seems to have gotten crossed at your end but we
cannot tell what.

Dirk
