Hi,

Trying today engine-setup to update from 4.3.3 -> 4.3.5 I got this error:

[ ERROR ] Failed to execute stage 'Setup validation': local variable 'snapshot_cl' referenced before assignment

In log file I see:

Any hints?

thanks

Giannis


After removing all snapshots, I was able to continue the upgrade.
