The Fix
This error may occur when attempting to connect to a vsftpd FTP server. You simply need to add one line to the configuration file, which this article assumes is in the default location of /etc/vsftpd/vsftpd.conf.
echo 'seccomp_sandbox=NO' >> /etc/vsftpd/vsftpd.conf
Be sure to restart vsftpd:
systemctl restart vsftpd
This error is likely caused by this bug: https://bugzilla.redhat.com/show_bug.cgi?id=845980. Turning off the Google Seccomp Sandbox for Linux fixes this issue.
