Previously I accidentally took ownership of my systems drive at that time I saw that the shutdown button was disabled so I thought there might be something wrong so I forcefully sutdown and now I am seeing following message on my boot up screen:
[TIME] Timed out waiting for device dev-zram0.device - /dev/zram0.
[DEPEND] Dependency failed for dev-zram0.swap - compressed swap on /dev/zram0.
[DEPEND] Dependency failed for email@example.com - create /dev/zram0.
I did not try anything because I’m new to linux and I don’t have any access to cmd currently so anyone can please help me out
Those messages seem unrelated, they are about zram.
Zram, in the way that is configured in Fedora by default, will take a part of your RAM and make it available as swap with some compression.
That will allow you to kinda of use more RAM than you actually have.
I will need more useful logs to help you.
Can you try pressing Esc while the machine is booting and check for any other interesting messages?
Yes, this is exactly what I thought would happen. Just to add some context:
In Linux, users are not recognized by their name, but rather by ther uid, a user identification
all non-system users’ identifications start with 1000 and go above.
system users (various users needed by the system, such as ftp, gdm) keep their IDs bellow 1000.
the root users always has the 0 ID.
What happened when you claimed the ownership was, that probably all files and directories were given to you, so now they are owned by user 1000. However, system services often cannot start when their files are not owned by a particular system user or root. For example, an ftp server will not start when its files are not owned by the ftp user.
You could, of course, change the ownership back easily, if you knew which file should belong to whom. However, as you do not have this kind of information anywhere and you probably do not remember the correct ownership of those files, the only solution is to reinstall the system.
If your disk is btrfs, there are ways to reinstall without having to remove the home folder which might save your data.
This is not incorrect. The plymouth service is a service that displays the nice booting screen with the Fedora logo and the spinning wheel and also the messages (that you have nicely photographed). When the service is no longer needed, after the boot, it will stop.
The question is why the installer has not started.
Interesting. In order to change the ownership of a file with chown you need to be root, or use sudo. From what’s written above, that utility allows any regular user to take ownership of anything, with the obvious potential to bork the system as seen here. How something so dangerous was ever allowed to be part of Fedora is incomprehensible. I don’t use Gnome, but I’d really, really appreciate it if somebody who does would open a Bugzilla on this ASAP!
That is, assuming you know the correct owners (could be easy if not running the recursive version) or some tool knows the correct owners (Maybe DNf could be used for this if it has a "reinstall every package feature?)
