Hi everyone, I just joined the forum because I have a problem !!!
I tried to install signal without success and now I am getting these errors.
E: Type ‘sudo’ is not known on line 2 in source list /etc/apt/sources.list.d/signal-xenial.list
E: The list of sources could not be read.
E: _cache->open() failed, please report.
Could you please help me?
