Add a ca root to ca-certificates in WSL environment?

[Jeffrey Walton]

Hi Everyone,

I'm working on a Windows machine with Windows Subsystem Linux (WSL).
The machine hosts Ubuntu 20.04. We are having some TLS problems due to
an interception proxy. I need to add a CA root to the ca-certificates
package or store.

I checked the Ubuntu wiki and found one article on ca-certificates at
https://wiki.ubuntu.com/IncidentReports/2011-09-20-ca-certificates-removes-libnss3.

I'm Ok with dropping the root CA in the filesystem and running
c_rehash, if needed. I'm happy to use the method if that is
recommended.

My question is, how would I go about adding a root CA to the machine's
trusted root store?

Thanks in advance.
