Report of a successful Ubunutu 22.04 install with some hiccups

[zkamvar]

I'm on Ubuntu 22.04 and I was able to install R-devel with a couple of hiccups. I'm not sure they best way to amend the current instructions, but here is my experience:

deb-src errors

apt-rdepends --build-depends --follow=DEPENDS r-base-dev | grep " B" | sed -e "s/  Build-Depends: //"

...
Error: You must put some 'deb-src' URIs in your sources.list 

I used sudo vim /etc/apt/sources.list and then used the command :g/^deb /t.|s/deb/deb-src/ to duplicate all the deb lines and copy the deb-src line.

This did not work until I realized three things:

1. the apt repository for R was commented out after my recent upgrade (instructions found here https://cran.r-project.org/bin/linux/ubuntu/)
2. some of the sources were moved to their own files in /etc/apt/sources.list.d/
3. I needed to run sudo apt update to get deb-src to work

Zombie Conda errors

After I was able to get the deb-src to work and pulled down the changes from svn, I compiled R inside the svn repo and I was getting make errors that said:

"$HOME/anaconda3/include/zlib.h" not found

I removed anaconda six months ago, but apparently there are still a few zombies wandering around.

I found the location of the offending config by searching for "anaconda" with ripgrep (I found it in src/main/dounzip.d) and then I found what zlib I actually had by using:

locate -r '\zconf.h$'

and then manually replaced the lines in src/main/dounzip.d.
