This: “No supported authentication methods available (server sent: publickey)” happened to me after I turned on Microsoft One Drive backup and sync for my files including the directory where I save my ssh key. In my case the solution is simple: just go to Putty => SSH => Auth and just (re)browse again to my same key and save, then it worked. It looks backup and sync software such as Microsoft One Drive (and may be the same with Google Drive), affect the way Putty sees and identifies directories if the key directory is specified then later installing or turning on backup and sync including that directory.
The public key generated by puttygen cannot be used directly on Ubuntu you need to change its format as mentioned here
Hope this helps
