ssh secure shell：server responded algorithm negotiation failed
This problem is usually solved as follows:
enter
1. cd /etc/ssh
2.vim /etc/ssh/sshd_config
# Add the following to the configuration file (except the last one of the third is gray plus purple, the others are blue, if it is gray means it is not right!)
Ciphers aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr,3des-cbc,arcfour128,arcfour256,arcfour,blowfish-cbc,cast128-cbc

Then restart sshd with this statement and you’re done
systemctl restart sshd
Because the error page can not be selected, so I did not directly check the error, but with their own understanding of the error to check, but wasted a lot of time, so if such an error, or hand typing in the future, it is very fast.
