Error when upgrading from version 4.2.2 to 5.1a7

Thanks for you reply Mark.
During my test, there is no error with 5.05 step.
I'll wait for the final release.

Nobody ?
The problem seems to be in step 10 during 5.0.6 alpha1.
I removed all cms widgets before the upgrade, unistalled all plugins.
Always stuck at step 10 :-(
