Rebooting after latest update loops to login screen.
Trying to login via TTY shows error
“error while loading shared libraries: libunistring.so.2: cannot open shred object file: No such file or directory”
Trying to run update via pacman results in same error.
Partial update state.
You should run from TTY:
sudo pacman-mirrors -f5 && sudo pacman -Syyu
Already tried this.
pacman-mirrors works but “sudo pacman -Syyu” again gives “error loading shared libraries: libunistring.so.2”
I can chroot and access tty but error remains same
Could you please provide the output of
pacman -Qm
Should this be understood as you cannot login using TTY?
This is from a live boot?
Also post
ldd /usr/bin/pacman
It’s either a partial upgrade or some AUR libs.
pacamn -Qm shows same error “error while loading shared libraries: libunistring.so.2”
And no, its not live boot, its on my manjaro installation

I asked because of your explicit mention of chroot - which is only used from live ISO.
Since pacman refuses to work - try pamac
pamac list -m
and if pamac refuses to work as it uses libalpm - we will have to consult the birds
pamac list -m
pamac: error while loading shared libraries: libunistring.so.2: cannot open shared object file: No such file or directory
The following is a dirty hack - you may - temporarily - try to work around the issue by symlinking
ln -s /usr/lib/libunistring.so.5 /usr/lib/libunistring.so.2
Then return to listing foreign packages
pacman -Qm
You need to fix the underlying issue - which is most likely caused by a custom package.
There is no guarantee this wil work and may create another issue - in any case - you must remove the symlink afterwards
rm /usr/lib/libunistring.so.2
pacman started working after this. But now plasmashell is not starting
“qt.qpa.xcb: could not connect to display”
Stay in TTY - as I said - you need to / must fix the underlying issue before you boot into a desktop.
You must remove whichever custom package listed by pacman -Qm then run a full system sync
sudo pacman -Rd $(pacman -Qqm)
sudo pacman -Syu
You can rebuild your custom packages later
Needy pacman. 
Then you are lucky. Update everything then - to me this still looks like a partial upgrade and
pacman -Q libunistring
probably shows v1.1-1 or even v1.0.
i must say that after your previous fix i rebooted. plasma(x11)was not booting but plasma(wayland) worked.
so currently i will stick to booting into wayland.
pacman -Q libunistring 1 ↵ 02:09 PM
libunistring 1.1-2
I said temporary - that means you must fix the underlying issue - otherwise you will get weird issues later on - the symlink is temporary - a bandaid - so fix the underlying issue.
Everything else is unsupported
i had this error of plasma(x11) not booting. i have custom theme instaled in lightdm. i will look into it.
Mkay… then it’s some other package. You still haven’t gave any info on full update or commands @linux-aarhus asked for. I’m not going to pry info out of you anymore.
Huh, what?
i think i have given any info asked by @linux-aarhus.
I am using KDE. plasmashell is not opening in x11 session but booting normally in wayland session.
due to some issue I have replaced the default SDDM with lightdm as login manager.
Please fix the underlying issue and remove the bandaid symlink mentioned above - this bandaid is how xy problem is created.
