From what I’ve checked here, this error refers to a PPA that does not support the current version of the system you are using. Refers to the everpad software (seems outdated). Have you added this repository manually?
To do not present this error you must disable or remove this PPA, so that the installation or even dependent packages can be upgraded successfully.
Solution for the PPA error:
How can I fix a 404 Error when using a PPA or updating my package lists?
How can PPAs be removed?
PS: If you need a Linux client alternative to Evernote try: NIXNOTE
Now finally on the issue of installing the driver/software for the operation of your device, try:
- Try reinstalling, but first resolve the PPA issue first.
- Uninstall, update your software repositories, and try to perform the installation again.
Maybe this will also help:

I hope it can work
