The DevOps Joint

Joplin is a versatile, open-source note-taking and to-do application that stands out among its peers for its commitment to privacy, security, and user control. Unlike proprietary alternatives like Notion and Evernote, Joplin ensures that your data remains your own, storing it in a simple SQLite database that you can easily manage and back up. Its end-to-end encryption makes sure your notes are accessible to only you, offering peace of mind that’s hard to match.

The installation of the newer version of Joplin seamless found my existing Joplin database, and allowed me to continue capturing my notes, including the some of the initial notes for this article:

The newer v3.1.24 version of Joplin now works just fine on Ubuntu 24.04 LTS.  If you’re having similar troubles with Joplin, give these steps a try.  Hopefully it resolves your problem so you can get back to capturing all your awesome ideas in your own secure, offline Joplin database.
