Yes, you need to disable all default wolfssl things if you want only openssl based
I commented out libwolfssl but I now see the package name is libwolfssl4.7.0.66253b90.
I don't recall package names usually having versions as part of the name so I'll try as suggested.
libopenssl1.1
libustream-openssl20201210
libwolfssl4.7.0.66253b90
Trying again.
Specifying the cert or not gives the same result.
curl: (77) CA signer not available for verification
Let's close this as it will not be of any use to someone who comes across it. At this point, we know what happened so time to build a new version but that is now another question.
As an update, I went ahead and purchased a cert from GoDaddy.
I cannot get a build to work with any letsencrypt site and I've started a new post asking for help with that so I can get back to letsencrypt at some point.
I am using the image builder, not source and I've not found any way to get past this so far.
I started a new question so as not to confuse whom ever finds this one.
I can confirm that recompiling curl and using OpenSSL as the SSL lib works. Understandably, this isn't going to be a solution for everyone unfortunately.
