[solved] Problems after uninstalling ncurses

joanmanel · 2017-10-30 12:43:18

After trying a system update, I was getting a error saying that some files already existed on my filesystem. This error came from ncurses. So I decided to uninstall it, and reinstall it.

I remove it doing -Rdd

But now my system is broken. If I try to go to root, for example, it gives

bash: error while loading shared libraries: libncursesw.so.6: cannot open shared object file: No such file or directory

If I try to reinstall it using sudo I get something like

[group@sparkling ~]$ sudo pacman -S ncurses

Packages (1) ncurses-6.0+20170902-2

Do you want to delete it? [Y/n] 
error: failed to commit transaction (invalid or corrupted package (PGP signature))
Errors occurred, no packages were upgraded.

I dont want to boot the computer because I am afraid it won't work again.

Is there any way to fix this?

Define "Try to go to root". Did you log in as root? Or did you, while logged in as a normal user, use the su command? If not the later, try that now.
When it gave you the opportunity do delete ncurses from your cache, please tell me you said "no"

libgcrypt depends on ncurses ... EVERYTHING DEPENDS ON NCURSES! (Ok, "virtually" ;-)

You'll likely have to fix the system offline: https://wiki.archlinux.org/index.php/Pa … an_upgrade (install ncurses from the installation medium)

seth, I was thinking they might be able to use LocalFileSigLevel = Optional iff they had not deleted the cached version.

sudo depends on libgcrypt - idk, but nuking ncurses is usually close to "game over" (also xz depends on ncurses ...)

That I did not know. Yeah, Tilt -- game over.

So I went through your link, and I was able to update the system with

pacman --root=/mnt --cachedir=/mnt/var/cache/pacman/pkg -Syyu

and then using a similar command I installed ncurses.

When I run the other command they say:

find /mnt/usr/lib -size 0

I actually got a lot of stuff going out, more than 5000 lines.

Anyway, I rebooted the system, and everything seems to be OK, it gives me green OKs during boot, but it doesnt go into GDM, it gets stuck in "[OK] Started accounts service", and doesnt go through that.

Stuff like "[OK] Started authorization manager" "Reached graphical Interface" "started gnome display manager" .... all these are also OK.

Empty files are expectable notably if you've linux-headers installed. (Also the check is not necessary. You did not face a corrupted update, but deliberately removed some crucial files)
