===== Проблемы с SSH =====
==== userauth_pubkey: signature algorithm ssh-rsa not in PubkeyAcceptedAlgorithms [preauth] ====

/etc/ssh/sshd_config

<file>
PubkeyAuthentication yes
PubkeyAcceptedKeyTypes=+ssh-rsa
</file>

Или более изящно
<file>
echo 'PubkeyAcceptedKeyTypes=+ssh-rsa' >/etc/ssh/sshd_config.d/pubkey_rsa.conf
systemctl restart ssh
</file>

====  userauth_pubkey: signature algorithm ssh-dss not in PubkeyAcceptedAlgorithms [preauth] ====
Аналогично предыдущему
<file>
echo 'PubkeyAcceptedKeyTypes=+ssh-dss' >/etc/ssh/sshd_config.d/pubkey_dss.conf
systemctl restart ssh
</file>

==== ssh: sign_and_send_pubkey: signing failed: agent refused operation ====
нужно выполнить:
<file>
ssh-add
</file>

==== no matching key exchange method found. Their offer: diffie-hellman-group14-sha1 ====
Сделать в файле ~/.ssh/config следующие строки
<file>
Host server_name server_ip
    KexAlgorithms +diffie-hellman-group14-sha1
</file>

==== no matching host key type found. Their offer: ssh-dss ====
Сделать в файле ~/.ssh/config следующие строки
<file>
Host server_name server_ip
    HostKeyAlgorithms +ssh-dss
</file>
