Skrooge won't start - incompatible Qt library

[Jim Patterson]

Just ran the upgrade to Cosmic, and installed Skrooge as Grisbi is no longer supported. However, it won't launch. I get a few warnings and then this fatal error:

##FATAL: Cannot mix incompatible Qt library (version 0x50901) with this library (version 0x50b00)
Aborted (core dumped)

Tried apt-get update / apt-get upgrade, but everything is up to date.

Note that skrooge most definitely IS installed - no idea why the system summary tacked on says it isn't. There are no custom packages on this system; everything is either from the core system or added using software-manager.

Jim issue is not about installed, not installed, but about successful installation. Skrooge is installed, but can not be lunched. Below please find runtime messages with CRITICAL and FATAL errors. Take a look inside package and try to resolve this.

Thanks for the confirmation. My followup on "not installed" was really a comment regarding the bug reporting system which had tagged "(not installed)" on the package name even though it was in fact installed.
I agree it does seem to be a package issue. However, Ubuntu is distributing the Skrooge package, and so an end user like myself should be able to just install it and go. I don't really understand the packaging system or skrooge well enough to sort this out myself.
