I tried to install udunits2 (because I need the sf package) in Linux by using:
install.packages("/panfs/roc/groups/5/.../udunits2_0.13.tar.gz", repos=NULL, type ="source")
But I´m getting this error message:

If the udunits2 library is installed in a non-standard location,
use --configure-args='--with-udunits2-lib=/usr/local/lib' for example,
or --configure-args='--with-udunits2-include=/usr/include/udunits2'
replacing paths with appropriate values for your installation.
You can alternatively use the UDUNITS2_INCLUDE and UDUNITS2_LIB
environment variables.
If udunits2 is not installed, please install it.
It is required for this package.

Then I tried installing:libudunits2-dev, libgdal-dev, libgeos-dev and libproj-dev. But any of them are available for R version 3.6.0.
Does anyone have a suggestion? I´ve tried so many things without success. Many thanks in advance!
You have misunderstood sf's dependencies. SF's required GDAL to perform. In Linux, specifically Ubuntu, this required installation of Ubuntu packages : libudunits2-dev, libgdal-dev, libgeos-dev and libproj-dev.
Whereas, udunits2 is an R package which also depends on Ubuntu's libudunits2. There is no need to install udunits2 for the installation of SF.
As mentioned in the ibusett's comment link, you can either execute this:
apt-get -y update && apt-get install -y libudunits2-dev libgdal-dev libgeos-dev libproj-dev
Or :
sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get update
sudo apt-get install libudunits2-dev libgdal-dev libgeos-dev libproj-dev
On Ubuntu's terminal, not your R's console.
