On a Linux base with python3 I can't install/setup calibre-6.23.0 ...

I have no idea why this is happening and I couldn't find a thorough step-by-step installation guideline. Perhaps the python setup can't 'run_...' these procedures because the user privileges were dropped.

How can I troubleshoot this problem?

I do corpora research and may have to heavily use calibre.

Did you try installing calibre from the Linux install page on the calibre-ebook.com website?

The command line from there would be:

sudo -v && wget -nv -O- https://download.calibre-ebook.com/linux-installer.sh | sudo sh /dev/stdin

There is also advice on prerequisites, manual installs, etc.

that one liner worked!:
$ which calibre
/usr/bin/calibre
$ calibre --version
calibre (calibre 6.23)
$ which ebook-convert
/usr/bin/ebook-convert
$ ebook-convert --version
ebook-convert (calibre 6.23.0)

Generally speaking, it seems that installing calibre using that one liner works better than using the various distro versions.
