Error: Conflicting values set for option Trusted regarding source

I have to install dbeaver in Ubuntu, so I'm trying to run this command:

sudo apt update && sudo apt install dbeaver-ce

but I am getting this error:

E: Conflicting values set for option Trusted regarding source http://cz.archive.ubuntu.com/ubuntu/ bionicE: The list of sources could not be read.

I tried with

deb [trusted=yes] http://br.archive.ubuntu.com/ubuntu/ bionic restricted main

but I am getting this error
