Hi,
I'm cleaning up older bugs and I'm sorry that this seems to have slipped through.
But as of today all these versions are unsupported - so I'd hope you just upgraded further and have it working.

If anything I'd point out from your log:
 unable to make backup link of './boot/xen-4.5-armhf' before installing new version: Operation not permitted

If there is anything set up in a special way that is a reason
