These days, I am using WSL (Ubuntu 18 TLS) in Window 10 machine instead of Putty for ssh and use Vim. I was a hard time to copy the code from Window 10 to past remote server.

Ctl+ Shift +V did not work or any other method. Copy Text from Window then moves to Ubuntu terminal then Change Vim to insert mode (insert) then use Right click of the mouse did job. ^^ Perfect~

I had troubles copying code from Windows 10 to paste in the remote server. Ctrl+Shift+V did not work or any other method.

My solution is: copy text from a window, then move to the Ubuntu terminal, then change Vim to insert mode (insert) then use the right click of the mouse.
