I had a similar issue, but assumed it was because I didn't have pandoc (or the right version of it..) installed.

c509dbd should have addressed this, I think? @mgeisler?

Thanks @djmitche
That might have been a transient error, it's working fine in my last PR (#1879)
I'll keep this open a little and close later today.

Can't reproduce it anymore.

Hmm... strange — the change in #1713 was not trying to fix this, it was just trying to simplify build.sh and also ensure that we always test the PDF generation for all languages for all PRs.

Cc @max-heller in case you have any ideas? The error message above says that pandoc wasn't found, so perhaps the curl command that installs it simply failed?

Yep, looks to be an issue of pandoc not being found in PATH, so either the download failed or adding it to PATH failed
