how did you install RKWard? if you are combining CRAN versions of R with older versions of ubuntu, you must install a version of RKWard that was copiled for your particular R version.

to make this easier, we are offering this PPA repository: https://launchpad.net/~rkward-devel/+archive/ubuntu/rkward-stable-cran

These are my entries for apt:

/etc/apt/sources.list:
deb https://ftp.fau.de/cran/bin/linux/ubuntu/ focal-cran40/

/etc/apt/sources.list.d/rkward-devel-ubuntu-rkward-stable-focal.list:
deb http://ppa.launchpad.net/rkward-devel/rkward-stable/ubuntu focal main

As Meik has pointed out, you will need http://ppa.launchpad.net/rkward-devel/rkward-stable-cran/ubuntu, instead, since you are using the "CRAN version" of R, rather than the one that comes with 20.04, by default.

It is true that the packages in our PPAs are currently missing dependency information that would have prevented you from installing this combination.

Comment 4 Jan 2022-06-03 11:28:24 UTC

There was a small difference in the names of the PPAs: rkward-stable vs. rkward-stable-cran
I did not see that.
Thank you very much, now it works.
