[R-sig-Debian] getting started with r2u

[ravi]

Ivan and Dirk,
Finally, finally, your mojo works!
1. I followed Ivan's suggestion. I ran bspm::enable() in a new R session. Installed a package. The process seemed to use r2u. Again, I followed Ivan and restored the following lines in the script:
echo "suppressMessages(bspm::enable())" >> ${RHOME}/etc/Rprofile.site
echo "options(bspm.version.check=FALSE)" >> ${RHOME}/etc/Rprofile.site
2. I then ran 
sudo ./add_cranapt_noble.sh
Before doing this, I made the file executable as program (after right clicking on the properties). After this, I was able to run the above command.
3. Now, the old error message about not being able to locate python3-{dbus,gi,apt} did not appear.
4. In a fresh R session, I was able to install packages via r2u.
5. One final question. I seem to have read somewhere that r2u provides binaries for about 5000 packages. If a particular package is not in a list, will I get a message? How will I know?
Thanks to you, Ivan. Thanks, Dirk, for your patient help.
Cheers, Ravi

That's actually a good debugging step:
- check if you can use r2u without bspm, ie try to run
    sudo apt install r-cran-digest
  or any other package with more depenendies
- if that works try to see why involving bspm does create an issue

As Ivan noted, it matters to re-enable bspm in /etc/R/Rprofile.site
