[darcs-devel] hub.darcs.net via ssh fails on ubuntu 18

[Ben Franksen]

It complains

Unable to negotiate with 173.255.254.113 port 22: no matching cipher
found. Their offer: aes256-cbc,aes192-cbc,aes128-cbc

I found that these are no longer supported by ssh by default, at least
on the latest ubuntu LTS. I have these in my /etc/ssh_config:

#   Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-cbc,3des-cbc

Adding aes256-cbc to my ~/.ssh/config fixes the problem. I am not sure
why they accept aes128-cbc by default but not aes256-cbc. This is strange.

Anyway, it would be nice if hub.darcs.net could also offer one of the
above listed ciphers.

Cheers
Ben
