To answer your questions:

-
"/ssh:admin@192.168.1.50#2130:/home/admin/boccaperta/contabilita/fattureods/078_crowdknitting.ods"
is a regular file, I can open it with LibreOffice Calc (.ods) via Dired
- the directory
"/home/manuel/documents/boccaperta/contabilita/boccaperta/reddito2015/fattureods/"
exists and it is writable
- no, same error.
