I've been using pkgdown::deploy_to_branch() for awhile now to publish my docs on the gh-pages branch of my repo, but as of this week it stopped working and has started giving me the following error:
Error: callr subprocess failed: server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none

When I tried to debug and got deeper into the function, this is the error I got trying to call build_site() directly:
Admittedly, authentication of all sorts is consistently baffling to me, but what has me really baffled is that my auth with github seems to be working in all other ways. I have it cloned with SSH. I can push and pull to my heart's content when I do it manually or through the RStudio GUI. Also, I can't figure out anything that has changed since the time when this was working.
Anyway, any help is much appreciated. I've also looked at a few other issues that came up when I googled the error (this one, for example) but none of them seem to be relevant to my situation where git is working fine except in this call.
Some details:
- I'm on Ubuntu 18.04.5 LTS (GNU/Linux 5.4.0-1054-aws x86_64)
- R 4.0.3
- pkgdown 1.6.1
- I tried this with two different repos (1 and 2, both of which were previously working with this same command and the same OS/versions/etc ^
Let me know if there are any more details that would help. Thanks!
