I had to reinstall my system (Arch Linux), so I created a new user home and copied the 2 joplin folders:
from my old home the new home in order to get my notes back.
Now, when I try to open Joplin, I see that several joplin processes are starting, but the Joplin GUI is not. In the logs I see the following error:
2020-10-12 12:01:19: "FetchError: request to http://localhost:8080/remote.php/dav/files/docker/Joplin/info.json failed, reason: connect ECONNREFUSED 127.0.0.1:8080 Code: ECONNREFUSED FetchError: request to http://localhost:8080/remote.php/dav/files/docker/Joplin/info.json failed, reason: connect ECONNREFUSED 127.0.0.1:8080 at ClientRequest.<anonymous> (/usr/share/joplin/resources/app.asar/node_modules/node-fetch/index.js:133:11) at ClientRequest.emit (events.js:210:5) at ClientRequest.EventEmitter.emit (domain.js:476:20) at Socket.socketErrorListener (_http_client.js:406:9) at Socket.emit (events.js:210:5) at Socket.EventEmitter.emit (domain.js:476:20) at emitErrorNT (internal/streams/destroy.js:92:8) at emitErrorAndCloseNT (internal/streams/destroy.js:60:3) at processTicksAndRejections (internal/process/task_queues.js:80:21)"
Any idea, how can I fix the error and get my notes back?
I managed to get my notes back after I replaced some of the old tables (all tables relevant to notes) in database.sqlite. I think the problem was that there was a change in the DB structure - I saw something related to fuzzy search, but I don't remember exactly.
