I followed the step as in https://fedoramagazine.org/upgrading-....

First thing: the grub menu doesnt show Fedora 29 after reboot. It shows Fedora 28 only with a new kernel version which came post a "dnf update".

Now when I start the system, there are a lots of failed statuses: Failed to start RealtimeKit Scheduling Policu Services Failed to start Accounts Services Failed to start firewalld - dynamic firewall daemon Failed to start Modem Manager Failed to start Avahi nDNS/DNS-SD stack Failed to start Virtual Machine Failed to start Disk Manager Failed to start NTP client/server and finally stuck at : "Started D-Bus System Message Bus".

I have to go into emergency mode to log into my account. Also, post login, my account password doesnt work for any command(eg: sudo dnf install xxx throws Sorry, try again).

I am able to gain login as root user to gain root access. All this started after I did a dnf update.

[root@localhost ~]# dnf history

Can someone please guide me on the steps to recover my system. Thanks in advance

if you had the same update luck a a host in Berlin last year, the d-bus components do not match and thats why it's not starting. Problem is, you can't use rpm if dbus is down.

Solution: Use a livedisk, boot from usb. open terminal. mount your systems hddisk to /mnt/ . chroot /mnt/ . dnf reinstall d-bus* .

You do come from booted system, so dbus is up and running and no program inside the chroot can complain about it. It is possible, that you need to link a dbus socket into the chroot, but try it as above first.

btw: when you have entered "chroot /mnt" you shoud execute "passwd" first, to set a root password and UNLOCK the root account that way. makes things easier in your emergency shell next time.
