#11528 closed Bug report (outdated)

GnuTLS error -9

Reported by: Brandon Williams Owned by:
Priority: normal Component: FileZilla Client
Keywords: GnuTLS, TLS, 9 Cc: brandon.w2055@…
Component version: 3.7.3 Operating system type: Linux
Operating system version: 17.3


None of the tickets opened previously by other people have been fully answered. Most went unanswered (by the submitter) and got closed. My issue is using the Linux distribution of Filezilla got me the following output when connecting from my computer:

Status:	Resolving address of
Status:	Connecting to
Status:	Connection established, waiting for welcome message...
Response:	220 Microsoft FTP Service
Command:	AUTH TLS
Response:	234 AUTH command ok. Expecting TLS Negotiation.
Status:	Initializing TLS...
Error:	GnuTLS error -9: A TLS packet with unexpected length was received.
Status:	Server did not properly shut down TLS connection
Error:	Could not connect to server

I run Linux Mint 17.3 Cinnamon 64 bit. This error occurred on February 23, 2018 and I've been running through possible solutions thus far. Before Feb. 23, I've been using a Mac to connect to the same server without any problems. The server information is (areas with <* *> are sensitive areas and are ommitted):

Host: <*site_domain*>.edu
Protocol: FTP - File Transfer Protocol
Encryption: Require explicit FTP over TLS
Logon Type: Normal
Username: <*user name*>
Password: <*password*>
Server Type: Default
~Other settings are set to default.

I've made sure all settings are correct and are identical to my Mac configuration. I've seen suggestions to edit TLS settings or config files and I'm both hesitant and incompetent in performing these solutions. Thank you for your time and I look forward to a reply at your earliest convenience.

*If it makes any difference, Filezilla was installed through mintInstall7.6.3 'Software Manager'

Resolution: outdated
Status: newclosed

You have to update to the most recent version of FileZilla, we cannot support antique versions.

Can you direct me to a specific installation guide for FileZilla 3.31.0?

comment:3 by Brandon Williams, 2 years ago

That is to say, sudo apt-get upgrade filezilla only says that the 3.7.3 is the latest version. When I download the tar file from and go through all the bells and whistles and go to either run ./filezilla or /opt/FileZilla3/bin/filezilla I get the following:

You need to compile FileZilla, and any missing dependencies, from source. The configure script will tell you what's missing.

I recommend installing FileZilla and the missing dependencies into a new prefix to avoid any conflict with existing system files.
