When uploading the puttygen generated RSA public key you must edit it in order to upload to the LTS via web. Example of puttygen generated SSH2-RSA public key:
ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAQEAo5kbmVf0ns3LTjTx1STdX67Log9tv3KoEACLWtJdqfJ8TX5mEElzp5nj/eUQhgjs015ANZaT4BAQr1T+8QHWc2eUBXp0kr4AXlH6oDqBGxKpioIL6wgIXDXVDsOjzSe/3GdK1FlUqE7rZGYLFnKbPBANCGwbKEZa/GGQAgCFMcuSuisFt60GHuig8Z9ZinPcJ9CLR1PSXIhaH8DfifHBnKiyDTzyByuBNB3Qt4rVCI+jtTeiZeiw8X41u6pMjVWXIQbZN6ntcdUH53RVGrmA6AAJk8hswDrQkbiWcgGswiBCpXkOdqOqj7JSP5xjt4ChhHu1fbeZs6XeZwGfmhGhnQ== rsa-key-20150716
You must remove the line in bold above. Now upload via the LTS web: Config->Users->"user"->Upload SSH Public Key
NOTE: The LTS does not support DSA keys.
