AttributeError: /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1: undefined symbol: EVP_CIPHER_CTX_cleanup
vim /usr/local/lib/python2.7/dist-packages/shadowsocks/crypto/openssl.py
将第52行libcrypto.EVP_CIPHER_CTX_cleanup.argtypes = (c_void_p,) 改为libcrypto.EVP_CIPHER_CTX_reset.argtypes = (c_void_p,)
再次搜索cleanup(全文件共2处,此处位于111行),将libcrypto.EVP_CIPHER_CTX_cleanup(self._ctx) 改为libcrypto.EVP_CIPHER_CTX_reset(self._ctx)
save and restart shadowsocks service
