I had to use the work-around documented here: https://issues.apache.org/jira/browse/ARROW-10371?jql=project%20%3D%20ARROW%20AND%20text%20~%20%22libcurl4-openssl-dev%22 (Download cmake 3.19.1, build it, and set CMAKE=<build location>.) to install arrow.

 

I'm sorry I don't have more ideas about the error. Without reading the code I'm not even sure what's going on in this part of the code.
