Upgrade to v0.18c - error upgrading ownCloud

Firstly, lots of people have said it before, but MiaB really is fantastic - thanks, @JoshData!

I just tried upgrading from v0.17c to v0.18c and encountered the following problem with the upgrade of ownCloud.

ownCloud is not installed - only a limited number of commands are available

  Command "upgrade" is not defined.

The mailinabox command then retries the ownCloud upgrade a second time, but it fails in the same way.

Does anyone have any ideas on how to work around this?

For me it’s failed with other reason:

ownCloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade
Set log level to debug - current level: 'Warning’
Exception: Updates between multiple major versions and downgrades are unsupported.
Update failed
Maintenance mode is kept active
Reset log level to ‘Warning’
