I'm trying to connect from a laptop (computer1) to a host (remote1). On computer1 I have user1 on the host I have a different user (user2). Both systems are running Debian, the remote1 system is a clean install of Debian Buster.
The error I'm receiving is the following:
Unable to connect to libvirt.
End of file while reading data: sh: 1: nc: not found: Input/output error
Verify that the 'libvirtd' daemon is running
on the remote host.
Libvirt URI is: qemu+ssh://[email protected]/system
Traceback (most recent call last):

I can ssh with user 1 from computer 1 to remote1 with:
user1@computer1:~$ ssh [email protected]
and I'm prompted with a password request. I also tried setting up passwordless login using private-public key and that works simply ssh-ing but trying virt-manager I get the error.
As soon as I try:
user1@computer1:~$ virt-manager -c 'qemu+ssh://[email protected]/system'
I get the error.
As it doesn't matter if I'm using public key or password authentication (I get the error in both scenarios) I reverted back to password authentication.
On remote1 I only have the following in /etc/ssh/sshd_config:
Port 22
PasswordAuthentication yes
ChallengeResponseAuthentication no
UsePAM yes
X11Forwarding yes
AcceptEnv LANG LC_*
Subsystem sftp /usr/lib/openssh/sftp-server
In /var/log/auth.log I can't seem to find a failed authentication.
Any idea/suggetion on what this is and why?

I'm new to Linux and sys-admin so after 3 days of tries and constant googling I'm at a loss.
virt-managerworks under the hood, yetnc: not foundsuggests something tries to usencand the executable cannot be found. If the setup really missesncthen try to add (install) it. Where? I don't know because it's not clear for me ifnc: not foundcomes from the local or the remote system. Ensuringncis available on both ends seems a good strategy. Also keep in mind there are at least two implementations; it's not clear which one is preferred or strictly required. Maybe it will work with any.
