Cannot export to PDF

[iamalsonothere]

When i try to export to PDF i get the following error in a new window:

nbconvert failed: xelatex not found on PATH, if you have not installed xelatex you may need to do so. Find further instructions at https://nbconvert.readthedocs.io/en/latest/install.html#installing-tex

I have xelatex and pandoc installed but the flatpak of Jupterlab-desktop does not appear to contain them. I tried allowing the flatpak of jupyer to access my real /usr/bin but to no avail.

@iamalsonothere Thanks for opening this issue! JupyterLab Desktop runs inside an environment of its own, so you may need to install xelatex and pandoc inside the terminal inside of JupyterLab Desktop. Are you able to do this? You can find documentation about this process here: https://nbconvert.readthedocs.io/en/latest/install.html#installing-pandoc

Also, which OS and version are you using, and which version of JupyterLab Desktop are you running?

I cannot do this, there are no package managers available inside a flatpak enviornment

Arch Linux
JupyterLab Desktop 4.2.5-1 from https://flathub.org/apps/org.jupyter.JupyterLab

I looked at the GitHub org related to this package — https://github.com/flathub/org.jupyter.JupyterLab — and found that its contributors may not be Jupyter contributors. Does this also happen when you install JupyterLab Desktop in another way mentioned in the README?

It does not occur when installed outside of Flatpak, but i made the issue here since the Flathub page links to this repo
