Hi all,

I'm trying to install pgadmin4 via "yum install pgadmin4" but it fails
with:
Errore: Pacchetto: 1:pgadmin4-python3-flask-1.0.2-2.rhel7.noarch
(pgdg-common)
            Richiede: python36-click
Errore: Pacchetto: pgadmin4-python3-sshtunnel-0.1.4-2.rhel7.noarch
(pgdg-common)
            Richiede: python36-paramiko
 Si può provare ad usare --skip-broken per aggirare il problema

I'm using the latest pgdg repository:
[root@localhost pgadmin4-4.20]# rpm -qa |grep pgdg
pgdg-redhat-repo-42.0-9.noarch
