The pdf-linter I use to verify a pdf document is qpdf,
<https://github.com/qpdf/qpdf>. It is available on most distributions,
including Debian, Fedora and Red Hat.
The command to check the document is `qpdf --check <doc>`.

qpdf may provide this functionality, but I have never used it. From
the project's description: "qpdf is a command-line tool and C++
library that performs content-preserving transformations on PDF files.
It supports linearization, encryption, and numerous other features. It
can also be used for splitting and merging files, creating PDF files
(but you have to supply all the content yourself), and inspecting
files for study or analysis."
Another tool I would look at is GhostScript. It looks like it can
convert to PDF/A: <https://stackoverflow.com/a/9343820>.
