Hello,
I cannot recover dude works.

Host is Commell-575, CompactFlash4GB, USB8GB. Dude stored to usb.
After rOS system fail(a month ago) and remake system with netinstall 6.19, when install Dude4.0beta3.npk, log says that is installed bud disabled.
Dude store always is backup mode, it cannot change to active.
In packages, don't appear dude packed!
I can downgrade to 3.6 and upgrade to 4, but never appear on packages.

What's wrong?

Thank you very much

Ros support for Dude was removed recently. Check ros release notes. Dude will not run in ros anymore.
