@Sebastien Bacher thank you very much for looking into this issue. I don't know if it is worth tracking this further.
I just moved the /tmp directory back to the / partition, to avoid further trouble. And this actually solved the issue. Like they did here: https://bbs.archlinux.org/viewtopic.php?id=217072 where this was mentioned: ``` systemd[476]: systemd-timesyncd.service: Failed at step NAMESPACE spawning /usr/lib/systemd/systemd-timesyncd: Too many levels of symbolic links systemd[1]: systemd-timesyncd.service: Main process exited, code=exited, status=226/NAMESPACE ``` I gave again full access `chmod 777 /tmp` and set the sticky flag `chmod +t /tmp`: ``` sebastian@home:/$ ll insgesamt 1551245 drwxr-xr-x 26 root root 4096 Feb 20 21:24 ./ drwxr-xr-x 26 root root 4096 Feb 20 21:24 ../ drwxr-xr-x 2 root root 4096 Feb 19 14:28 bin/ drwxr-xr-x 5 root root 1024 Feb 19 14:28 boot/ drwxr-xr-x 2 root root 4096 Dez 13 00:54 cdrom/ drwxr-xr-x 23 root root 4660 Feb 20 21:25 dev/ drwxr-xr-x 162 root root 12288 Feb 20 19:18 etc/ drwxr-xr-x 6 root root 4096 Feb 13 20:12 home/ lrwxrwxrwx 1 root root 33 Jan 31 16:55 initrd.img -> boot/initrd.img-4.15.0-45-generic lrwxrwxrwx 1 root root 33 Jan 31 16:55 initrd.img.old -> boot/initrd.img-4.15.0-44-generic drwxr-xr-x 25 root root 4096 Dez 13 20:17 lib/ drwxr-xr-x 2 root root 4096 Jan 31 23:51 lib32/ drwxr-xr-x 2 root root 4096 Jul 25 2018 lib64/ drwxr-xr-x 2 root root 4096 Jan 31 23:51 libx32/ drwx------ 2 root root 16384 Dez 13 00:53 lost+found/ drwxr-xr-x 3 root root 4096 Dez 13 02:01 media/ drwxr-xr-x 2 root root 4096 Jul 25 2018 mnt/ lrwxrwxrwx 1 root root 9 Feb 13 20:02 opt -> /home/opt/ dr-xr-xr-x 298 root root 0 Feb 20 21:25 proc/ drwx------ 10 root root 4096 Jan 11 21:09 root/ drwxr-xr-x 40 root root 1320 Feb 20 21:25 run/ drwxr-xr-x 2 root root 12288 Feb 19 14:28 sbin/ drwxr-xr-x 9 root root 4096 Dez 20 18:40 snap/ drwxr-xr-x 2 root root 4096 Jul 25 2018 srv/ -rw------- 1 root root 1588346880 Dez 13 00:53 swapfile dr-xr-xr-x 13 root root 0 Feb 20 21:25 sys/ drwxrwxrwt 16 root root 12288 Feb 20 21:27 tmp/ drwx------ 4 root root 4096 Dez 17 23:16 .Trash-0/ drwxr-xr-x 12 root root 4096 Jan 31 23:51 usr/ drwxr-xr-x 15 root root 4096 Dez 16 21:54 var/ lrwxrwxrwx 1 root root 30 Jan 31 16:55 vmlinuz -> boot/vmlinuz-4.15.0-45-generic lrwxrwxrwx 1 root root 30 Jan 31 16:55 vmlinuz.old -> boot/vmlinuz-4.15.0-44-generic ``` -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1816630 Title: Gnome Control Center does not start due to GDBus.Error:org.freedesktop.DBus.Error.TimedOut To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1816630/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
