Hi folks, after upgrading a Centos container (LXC) from 7.4 to 7.5 I got this: # systemctl status Failed to get D-Bus connection: Connection refused # busctl Failed to connect to bus: Connection refused # ps -ef | grep db[u]s dbus 55 1 0 Jul02 ? 00:00:00 /usr/bin/dbus-daemon --system --address=systemd: --nofork --nopidfile --systemd-activation # lsof -p 55 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME dbus-daem 55 dbus cwd DIR 8,4 4096 130819 / dbus-daem 55 dbus rtd DIR 8,4 4096 130819 / dbus-daem 55 dbus txt REG 8,4 223344 133569 /usr/bin/dbus-daemon dbus-daem 55 dbus DEL REG 8,4 393485 /var/lib/sss/mc/initgroups dbus-daem 55 dbus mem REG 8,4 37240 150982 /usr/lib64/libnss_sss.so.2 dbus-daem 55 dbus mem REG 8,4 62184 150786 /usr/lib64/libnss_files-2.17.so dbus-daem 55 dbus mem REG 8,4 68192 141459 /usr/lib64/libbz2.so.1.0.6 dbus-daem 55 dbus mem REG 8,4 90664 140578 /usr/lib64/libz.so.1.2.7 dbus-daem 55 dbus mem REG 8,4 99944 150835 /usr/lib64/libelf-0.170.so dbus-daem 55 dbus mem REG 8,4 19896 140110 /usr/lib64/libattr.so.1.1.0 dbus-daem 55 dbus mem REG 8,4 402384 132708 /usr/lib64/libpcre.so.1.2.0 dbus-daem 55 dbus mem REG 8,4 88776 150757 /usr/lib64/libgcc_s-4.8.5-20150702.so.1 dbus-daem 55 dbus mem REG 8,4 19776 150776 /usr/lib64/libdl-2.17.so dbus-daem 55 dbus mem REG 8,4 297360 151443 /usr/lib64/libdw-0.170.so dbus-daem 55 dbus mem REG 8,4 106848 150792 /usr/lib64/libresolv-2.17.so dbus-daem 55 dbus mem REG 8,4 19384 141564 /usr/lib64/libgpg-error.so.0.10.0 dbus-daem 55 dbus mem REG 8,4 535064 141290 /usr/lib64/libgcrypt.so.11.8.2 dbus-daem 55 dbus mem REG 8,4 85952 150956 /usr/lib64/liblz4.so.1.7.5 dbus-daem 55 dbus mem REG 8,4 157424 140323 /usr/lib64/liblzma.so.5.2.2 dbus-daem 55 dbus mem REG 8,4 44448 150794 /usr/lib64/librt-2.17.so dbus-daem 55 dbus mem REG 8,4 1139680 150778 /usr/lib64/libm-2.17.so dbus-daem 55 dbus mem REG 8,4 20032 140130 /usr/lib64/libcap.so.2.22 dbus-daem 55 dbus mem REG 8,4 2173512 146385 /usr/lib64/libc-2.17.so dbus-daem 55 dbus mem REG 8,4 144792 144798 /usr/lib64/libpthread-2.17.so dbus-daem 55 dbus mem REG 8,4 23968 141464 /usr/lib64/libcap-ng.so.0.0.0 dbus-daem 55 dbus mem REG 8,4 127096 146315 /usr/lib64/libaudit.so.1.0.0 dbus-daem 55 dbus mem REG 8,4 155784 150814 /usr/lib64/libselinux.so.1 dbus-daem 55 dbus mem REG 8,4 173320 140201 /usr/lib64/libexpat.so.1.6.0 dbus-daem 55 dbus mem REG 8,4 203800 151456 /usr/lib64/libsystemd.so.0.6.0 dbus-daem 55 dbus mem REG 8,4 333408 144514 /usr/lib64/libdbus-1.so.3.14.14 dbus-daem 55 dbus mem REG 8,4 164240 150767 /usr/lib64/ld-2.17.so dbus-daem 55 dbus 0u CHR 1,3 0t0 129677343 /dev/null dbus-daem 55 dbus 1u unix 0xffff8f56b7b2cc00 0t0 129677608 socket dbus-daem 55 dbus 2u unix 0xffff8f56b7b2cc00 0t0 129677608 socket dbus-daem 55 dbus 3u unix 0xffff8f56bbbb3800 0t0 129676115 /run/dbus/system_bus_socket dbus-daem 55 dbus 4u a_inode 0,11 0 8547 [eventpoll] dbus-daem 55 dbus 5r REG 8,4 10406312 393485 /var/lib/sss/mc/initgroups (deleted) dbus-daem 55 dbus 6u sock 0,8 0t0 129677256 protocol: NETLINK dbus-daem 55 dbus 7r a_inode 0,11 0 8547 inotify dbus-daem 55 dbus 8u unix 0xffff8f56b80c4c00 0t0 129677257 socket dbus-daem 55 dbus 9u unix 0xffff8f56ba3aec00 0t0 129677258 socket dbus-daem 55 dbus 10u unix 0xffff8f56b7681000 0t0 129681025 /run/dbus/system_bus_socket Please note the "/run/dbus/system_bus_socket". AFAICT thats new. Shouldn't it listen on /var/run/dbus/system_bus_socket for backward compatibility as well? Is there is a way to fix this? Every helpful comment is highly appreciated. Harri
