Package: ifupdown Version: 0.8.36+nmu1 Severity: minor When upgrading:
Setting up ifupdown (0.8.36+nmu1) ... Installing new version of config file /etc/init.d/networking ... ifupdown.postinst: Warning: /etc/network/interfaces does not exist I now use NetworkManager by default, so that /etc/network/interfaces is not necessary. And AFAIK, the network can also be managed by systemd. (I'm not sure whether ifupdown is still useful, but I think that the ifup and ifdown commands may become necessary in case of issue with NetworkManager.) -- Package-specific info: --- /etc/network/interfaces: MISSING -- System Information: Debian Release: 11.0 APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'stable-security'), (500, 'unstable'), (500, 'testing'), (500, 'stable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-8-amd64 (SMP w/8 CPU threads) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=POSIX, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages ifupdown depends on: ii adduser 3.118 ii iproute2 5.13.0-2 ii libc6 2.31-16 ii lsb-base 11.1.0 Versions of packages ifupdown recommends: ii isc-dhcp-client [dhcp-client] 4.4.1-2.3 Versions of packages ifupdown suggests: ii ppp 2.4.9-1+1 pn rdnssd <none> -- Configuration Files: /etc/default/networking changed: VERBOSE=yes -- no debconf information -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
