I´ve reinstalled imunify a few times, but this didn´t solve the problem.
thanks

It's more likely because the source list is missing. Not sure how you tried to reinstall it but you could try following this article to see it if helps: https://support.plesk.com/hc/en-us/...-the-troubleshooting-guide-or-contact-support

If a Plesk package requires a third-party package of a certain version and it cannot be installed by the package manager, the update will fail.
Apply the latest OS updates on the server. On Debian: apt-get update && apt-get upgrade.

What's the output of?
#cat /etc/apt/sources.list.d/imunify360.list
