wpa_supplicant não está se conectando, porque o SSL3 não é suportado

Question

Eu tenho um laptop rodando o Debian GNU / Linux Unstable com o Network Manager. Desde uma atualização do OpenSSL (1.1.1, eu acho), não consigo me conectar a uma rede Wi-Fi usando o WPA2 Enterprise com PEAP (MSCHAPv2). Em /var/log/syslog , diz que o SSL3 não é suportado:

Descloquear o OpenSSL corrige, é claro, mas eu não posso usar coisas que são compiladas para versões mais novas do OpenSSL. Existe alguma maneira de se conectar à rede Wi-Fi?

O

link parece ser relevante. Sugere a edição das duas últimas linhas em /etc/ssl/openssl.conf . Certifique-se de usar o TLSv1.0, foi isso que funcionou na minha instalação horrível do MS AD.

Obviamente, deve-se pedir ao SysAdmin amigável que pare de usar software proprietário ou, pelo menos, que aceite novas versões de protocolo.
