- Distro: Ubuntu 19.10
It looks like a result of a wrong installation procedure (you must unpack the extension file prior to attempting to install). I could not find any other way than deleting everything from the uno_packages subdirectory in the user profile and reinstalling necessary extensions.
@gabix LO should let user uninstall it somewho. This represents LO weakness.
