Instalando Python 3.7 da fonte: test_ssl falhou

Para poder instalar o Python a partir do código-fonte sem permissão de root em um servidor Ubuntu, tive que instalar o openssl, o que fiz usando os seguintes comandos:

wget https://www.openssl.org/source/openssl-1.1.1e.tar.gz
tar -xzvf openssl-1.1.1e.tar.gz
cd openssl-1.1.1e
./config --prefix=${HOME}/.local/openssl --openssldir=${HOME}/.local/openssl
make -j$(nproc)
make install_sw

Então eu configurei o seguinte ~/.bashrc:

export PATH=$HOME/.local/openssl/bin:$PATH
export LD_LIBRARY_PATH=$HOME/.local/openssl/lib:$LD_LIBRARY_PATH

e criou um link simbólico da nova certspasta para a existente (esta etapa é necessária):

ln -s /etc/ssl/certs $HOME/.local/openssl/certs

Então comecei a instalar o Python 3.7.7:

wget https://www.python.org/ftp/python/3.7.7/Python-3.7.7.tgz
tar -xzvf Python-3.7.7.tgz
cd Python-3.7.7
./configure --enable-shared --enable-optimizations --with-openssl=${HOME}/.local/openssl --prefix=${HOME}/.local
make -j$(nproc)

Eu obtive:

== Tests result: FAILURE ==

385 tests OK.

4 tests failed:
    test_imaplib test_ssl test_tarfile test_urllib2_localnet

27 tests skipped:
    test_bz2 test_curses test_dbm_gnu test_dbm_ndbm test_devpoll

    test_urllib2net test_urllibnet test_winconsoleio test_winreg
    test_winsound test_xmlrpc_net test_zipfile64

O SSL parece ser o mais crítico, então executei-o novamente no modo detalhado para ter mais detalhes:

./python -m test -v test_ssl

Parece que ainda tenho problemas com certificados.

Eu apreciaria muito sua ajuda para resolver esse problema. Muito obrigado antecipadamente!

O teste falha devido a uma mudança de comportamento no OpenSSL 1.1.1e. Experimente com OpenSSL 1.1.1d por enquanto. Verhttps://bugs.python.org/issue40018Para maiores informações.
