Just putting it on TJC as I had this problem and fixed it.

All of a sudden, I could not connect to my XA2 from MacOS running OpenSSH v7.9p1

running ssh with the -vvv flag showed that there was a problem with the cipher used. Solution is:

either to use -c <ciphername> on the command line, e.g. ssh -c aes256-ctr nemo@<IP>,
or modify your /etc/ssh/ssh_config with something like this:

Host xperiaxa2 Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc

Hey,

I had the same problem with my installation too, solution:

devel-su
pkcon refresh
pkcon update

this should install a non faulty ssh version.

Comments

i just did that to test, but that does not fix the problem
