Erreur installation application PGADMIN

Bonjour à tou.te.s,
Pour info, j’ai exactement le même soucis lors de l’installation :

Could be due to having some recent openssl version …

Can you tell what gives

dpkg --list | grep openssl
ii  libcurl4-openssl-dev:amd64            7.52.1-5+deb9u10                                              amd64        development files and documentation for libcurl (OpenSSL flavour)
ii  openssl                               1.1.1g-1+0~20200421.17+debian9~1.gbpf6902f                    amd64        Secure Sockets Layer toolkit - cryptographic utility
ii  perl-openssl-defaults:amd64           3                                                             amd64        version compatibility baseline for Perl OpenSSL packages
ii  python-openssl                        16.2.0-1                                                      all          Python 2 wrapper around the OpenSSL library

Thank you Aleks :wink:
