Software to check PDF-UA compatibility?

My university is pushing for us to ensure that all our documents are accessibility-friendly. I write all my documents in LaTeX and have been taking the steps and measures to ensure that everything I generate is tagged, has alt text, and colour-blind-friendly.

Unfortunately, it seems the only way I can check for PDF-UA compatibility is with Acrobat Pro which the uni does not provide for us. What's more is that I use Linux and Acrobat doesn't work in that OS.

Is there a Linux-friendly libre software that can check if my PDF document is compatible with the machine-checkable requirements of Matterhorn Protocol?

VeraPDF seems like the best option when it comes to openness, being free, and having Linux support (really it uses Java, so it's just platform agnostic).

A second option might be this one:

I've never used it, and it only has a Windows installer, but you might still be able to make use of it with Wine/Bottles/etc. Also, it's free, so testing it out shouldn't cost anything but time.
