I'm on Linux (Ubuntu 20.04) and hadn't taken a note of what version of Joplin was installed but now the upgrade has failed and I can't find the exact version because the app doesn't load. It looks like it was going from 1.5 to 1.7 or from 15 to 17 because there are directories with those names on my computer.
I'm syncing with DropBox.
It told me it was doing the update and the next time I looked it had the following message:
request to https://content.dropboxapi.com/2/files/download failed, reason: unable to verify the first certificate FetchError: request to https://content.dropboxapi.com/2/files/download failed, reason: unable to verify the first certificate at ClientRequest.<anonymous> (/snap/joplin-desktop/17/linux-unpacked/resources/app.asar/node_modules/@joplin/lib/node_modules/node-fetch/index.js:133:11) at ClientRequest.emit (events.js:310:20) at ClientRequest.EventEmitter.emit (domain.js:482:12) at TLSSocket.socketErrorListener (_http_client.js:426:9) at TLSSocket.emit (events.js:310:20) at TLSSocket.EventEmitter.emit (domain.js:482:12) at emitErrorNT (internal/streams/destroy.js:92:8) at emitErrorAndCloseNT (internal/streams/destroy.js:60:3) at processTicksAndRejections (internal/process/task_queues.js:84:21)
I have other laptops (Mac) also syncing but I'm on the train and don't have access to that one to see if it is also failing.
Any help would be much appreciated. I can't really find any clues in the message that might show me what the problem is. Also can't find a way to retry the upgrade.
