Unable to open or create local sync database

upgrade
help

#1

I recently upgraded my server from 8.0 to 8.1 (I’m moving slowly towards a more current release, but I just finally moved the server to RHEL 7). In the process, I found that the client on my Mac was not syncing. It was not taking my username and password event though I had no problems accessing the code through the web interface.

Expected behaviour

I upgraded the MacOS client from version 1.7 to 2.4 by downloading and running the latest installer.
I expected to resume normal syncing, possibly after re-entering my credentials.

Actual behaviour

I got a series of error messages stating “Unable to open or create local sync database”
I checked $HOME/owncloud/.csync_journal.db (and other .files) and they all have mode 644 and are owned by me. The owncloud folder has mode 755.

Do I need to do some kind of upgrade on the local database?

Easier than I thought. Turns out rebooting the system fixed the problem. Must have been a frozen lock on the file.
