lftp remot file has data get to local file is empty

Question

I'm running lftp and I've encountered the strangest error. Whether I run the mirror command or just a normal connection the results are the same.

1. Connect to the remote site
2. Login
3. Go to outgoing directory
4. ls see that file have data.
5. get any file
6. disconnect
7. ls local, file is empty.

It is the most bizarre thing, has anyone seen this before?

Answer 1

Check out lftp 4.9.2 or newer version which fixed an issue for file download. It worked for me.

Please refer to https://github.com/lavv17/lftp/issues/312.

Answer 2

I had this happen to me before. It's that the ssh key has not been added to the systems/users known_hosts file yet.

First you must ssh to the site normally. It will prompt you to accept the ssh key, say yes. Then disconnect and use lftp again and it should work now that the key is accepted.
