Source: vsftpd Severity: critical Tags: ipv6 Justification: breaks the whole system
Dear Maintainer, In some case (eg. embeded devices or private network), it sounds good to desactivate ipv6. But when ipv6 is desactivated, for exemple with "ipv6.disable=1" into the GRUB_CMDLINE_LINUX, the vsftpd package can't be use, but also can't be installed, or reinstalled, since installation fail when postinst fail to start vsftpd service. Fail during package install/upgrade is critical because it may leave the system in a brocken state (cf. "apt-get check"). To at least decrease the severity of the bug, a workaround could be to NOT start or restart vsftpd service during install or upgrade, or maybe better : to check ipv6 (somewhere in /proc) before to start or restart service in postinst. -- System Information: Debian Release: 9.11 APT prefers oldstable APT policy: (500, 'oldstable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-11-amd64 (SMP w/32 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system)
