Package: network-manager Version: 1.27.90-3 Severity: normal After upgrading to 1.27.91-1, I've found that connecting to my VPN causes my existing "nameserver" option to disappear from /etc/resolv.conf.
Before connecting: ---- # Generated by NetworkManager nameserver 192.168.1.1 ---- After connecting (actual search domains obfuscated): ---- # Generated by NetworkManager search foo bar baz ---- I've downgraded back to version 1.27.90-3 which restores the desired behavior of retaining the existing nameserver setting: ---- # Generated by NetworkManager search foo bar baz nameserver 192.168.1.1 ---- Note that I have the VPN's "DNS / Automatic" toggle disabled. -- System Information: Debian Release: bullseye/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable'), (1, 'experimental-debug'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.9.0-1-amd64 (SMP w/4 CPU threads) Kernel taint flags: TAINT_FIRMWARE_WORKAROUND Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.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 network-manager depends on: ii adduser 3.118 ii dbus 1.12.20-1 ii libaudit1 1:2.8.5-3.1 ii libbluetooth3 5.55-1 ii libc6 2.31-4 ii libcurl3-gnutls 7.72.0-1 ii libglib2.0-0 2.66.1-2 ii libgnutls30 3.6.15-4 ii libjansson4 2.13.1-1 ii libmm-glib0 1.14.6-0.1 ii libndp0 1.6-1+b1 ii libnewt0.52 0.52.21-4+b2 ii libnm0 1.27.90-3 ii libpam-systemd 246.6-2 ii libpsl5 0.21.0-1.1 ii libreadline8 8.0-4 ii libselinux1 3.1-2+b1 ii libsystemd0 246.6-2 ii libteamdctl0 1.31-1 ii libudev1 246.6-2 ii libuuid1 2.36-3+b1 ii policykit-1 0.105-29 ii udev 246.6-2 ii wpasupplicant 2:2.9.0-15 Versions of packages network-manager recommends: ii crda 4.14+git20191112.9856751-1 ii dnsmasq-base [dnsmasq-base] 2.82-1 ii iptables 1.8.5-3 ii modemmanager 1.14.6-0.1 ii ppp 2.4.7-2+4.1+deb10u1+b1 Versions of packages network-manager suggests: ii isc-dhcp-client 4.4.1-2.1+b2 pn libteam-utils <none> -- no debconf information
