SCP did not finish successfully (1) Error when Trying to Upload from windows to Ubuntu using ruby

Question

My code

IMAGE_DIR = 'D:\File_Server\Nisa_Costcutter\Master Nisa CC Logos'

require 'net/ssh'
require 'net/scp'

def scopy_file(file)
  puts "Transferring #{file.path}"
  Net::SCP.upload!('192.168.254.5', 
                   'passenger', 
                    file, 
                    '/var/www/pinpointlms.co.uk/shared/logos', 
                    :ssh => {password: '*****'})
end

puts "Starting Upload"

Dir.foreach(IMAGE_DIR) do |name|
  if name.length > 4 && name[-4..-1].upcase == '.BMP'

    filename=name.strip()
    file = File.new(File.join(IMAGE_DIR, filename))

    if (Time.now - file.mtime) > 86400
        scopy_file(file) 
    end


  end


end
puts "End of Transfer"

I am trying to copy some files from a windows box to an Ubuntu box using Ruby but I get the following output:

I am a ruby beginner so any help you can give me on how to debug this code further will be much appreciated.

Thanks

Answer 1

You probably don't have user access to upload (write) that file in the given directory '/var/www/pinpointlms.co.uk/shared/logos' on your Ubuntu server.

Try to save it without giving it a full path, so it ends up in the user's home directory on the Ubuntu server. If this will work, then your problem is related with the user permission on the server.

Answer 2

In case it's helpful for others, I got the exact same error as this when trying to upload a file to a path that didn't yet exist. scp from shell will allow you to do this, but Net::SCP will fail with this error.

i.e.

scp "my.file" "/foo/bar/"

if /foo exists but /foo/bar/ does not, scp will create /foo/bar and put your file there (assuming permissions allow you to do this).

However - under the same circumstances - this will fail with the error given in the question

scp.upload!(my_file, "/foo/bar/")

The only solution I've found is to first create the path you want locally, and then upload with the :recursive option on, like so:

scp.upload!("bar/", "/foo" :recursive => true)

where ./bar contains my_file.
