QUESTION
I have this weird issue with my code on Raspberry Pi 4.
...ANSWER
Answered 2020-May-04 at 17:27After you write the file, the file pointer is at the end. So if you pass file handle to FTP
, it reads nothing. Hence nothing is uploaded.
I do not have a direct explanation for the fact the local file ends up empty. But the strange way of combining "append" mode and reading may be the reason. I do not even see a+
mode defined in open
function documentation.
If you want to both append data to a local file and FTP, I suggest your either:
- Append the data to the file – Seek back to the original position – And upload the appended file contents.
- Write the data to memory and then separately 1) dump the in-memory data to a file and 2) upload it.

Most Linux distributions have a mail service (including an MTA) installed. Ubuntu doesn't though.
You can install a mail service, postfix for example, to solve this problem.
