I just add my few points here - this issue is as old as the Collabora on Nextcloud - can’t export PDFs nor print. Tried to install fonts, install MS fonts repo, no fun.
My installation is clean, no Docker - NC 27.1.1, NC Office 8.2.0, PHP 8.1.2, PGSQL 14.9

Same here, i can’t export or download as PDF file.
No error or logs …
Nextcloud installed in VM.
Nextcloud : 27.1.1
Collabora Online - Built-in CODE Server : 23.5.403
Nextcloud Office : 8.2.0
PHP with OPCache : 8.2.7
MariaDB (MySQL) : 10.11.3

I created a real CODE hosted in a VM and moved to it, all is OK.
This append only using build in CODE server.

Prefer a dedicated CODE server against a build in

I’m having the same problem. More testing revealed the following:

  1. ImageMagick was giving an error because read|write access was not allowed. I updated the configuration file and the error went away, but the export/download still does not work.
  2. Here is my current situation…
    …I AM able to print to pdf using the print facility.
    …I am not able to Export AS pdf OR epub. In both cases the dialog (choose file name and options) appears until the final [Export] button. Then, it simply does not work. I haven’t been able to find any more information in the log files.
    …I am not able to Download epub, pdf, or ‘as PDF’. In all cases the file is created with a length of 0 bytes.

Here’s my environment:
Nextcloud version: '27.1.3`

Operating system and version: Ubuntu 22.04.02 LTS
Apache or nginx version: Apache/2.4.52 (Ubuntu)
PHP version: PHP 8.2.12 (cli)
Database: mysql 10.6.12

Collabora Online - Built-in CODE Server: 23.5.502
Nextcloud Office: 8.2.1

I’m happy to do the troubleshooting steps, but I’m not sure where to check next. Any help would be appreciated.

If it’s any help, my fix was to move away from the bundled Collabora app that has this problem in the AppImage, and just install Collabora on my server:

You may also want the web server conf and certbot suggestions from this page too:

Thank you for your help. I had already tried to install everything using those excellent resources. I still couldn’t get the pdf or epub export to work.

I changed my installation to a collabora docker image using help from here.
Now, everything is working fine.
Thanks again for your help!
