I cannot install the plugin on a stock Ubuntu 22.04 installation. Am I missing some requirements?

Ubuntu 22.04 switched from OpenSSL 1.X to OpenSSL 3. The latest release of the plugin doesn't yet support this, you'll need to download the latest development version (either from Github or from the 2nd post of the Mobileread thread.

As soon as the bug is actually fixed in the oscrypto library (the beta is currently using a hacky workaround) there will be a new release with the bugfix.

Thanks for the quick reply!

Version v0.0.16 is now released so I'm closing this bug report.
