I've been using Obsidian for a long time. I enjoy it and all of its extensions. However setting up the app and syncthing on all of my systems gets irritating.
Any way, after a little looking around, I found Trillium notes. It doesn't quite have all the extensions, but is easier to setup. Give it a look, see what you think
I've been getting around that mostly with Chocolatey and other PowerShell scripts on Windows. I'm sure the same can be done on Linux.
Are you hosting the desktop or server version of Trilium?
