I ran into the following error earlier this year and have yet to write about it. Adobe has the correct solution in another knowledge base article however the error messages are different. Since the errors looked to be different I never would have attempted the solution until Karl gave me a poke.
Basically I would launch Adobe’s Creative Cloud Packager (CCP) tool and nothing would work. Luckily the fix is really simple:
rm -rf ~/Library/Application\ Support/Adobe/OOBE
Adobe Unknown Server Error
