I'd like to add that the backend should be available for alpine, too, since the community AIO uses an alpine based image. It could be a good idea to add some install instructions for the AIO in the readme, too.

Note for everyone stumbling across this while googling: It is possible to install additional apks to the Nextcloud AIO container through the environment variable NEXTCLOUD_ADDITIONAL_APKS=imagemagick openjdk11-jre

Hi,

Thanks for your feedback on files_emailviewer. OpenJDK and wkhtmltopdf are required by the Email to PDF Converter. We've added them to our README and the app store description to inform about this upfront.

I agree that the situation with wkhtmltopdf isn't ideal. Currently, the package is available for most Linux distributions, except for newer Alpine releases, but that may change in the future.

If there's an alternative to the Email to PDF Converter, we can certainly extend this app to support multiple backends.

There's a community app by @newroco (https://github.com/newroco/emlviewer) which is able to display EML files without the need to convert them into PDF. However, this app has some display issues currently and it is only capable of displaying EML files (no MSG).
