Hi!
I tried to backup some files from my server with scp and failed:
$ scp -v root@the.server:/root/a.file .
Executing: program /usr/bin/ssh host the.server, user root, command
scp -v -f /root/a.file
OpenSSH_8.2p1, OpenSSL 1.1.1f 31 Mar 2020

Unable to negotiate with 192.168.1.11 port 22: no matching key
exchange method found. Their offer:
diffie-hellman-group1-sha1,diffie-hellman-group14-sha1
I tried OpenSSH_8.0p1-2 which is still available in the cygwin
setup-x86_64.exe wizard and that version works fine.
(the version above is 8.2.p1-1 in the setup wizard)
Regards,
David
