Broken pacman with the update.

This was the most stupid thing i have done in my 4 years of ArchLinux journey.

Normally i came to read the news, then the forums about possible problems and then update. But this time(this damn first time) i was hurrying for the update. I make an 'pacman -Syu' and i told me to update pacman first. When i try to update i failed because of the damn Yaourt's damn package-query. And i made my first mistake:

'pacman -Rd pacman'

Pacman became broken. Then what i did in this area i can not remember but i think i extracted pacman to the root then tried again for a full system update. Everything went fine. All system up-do-date. But pacman broke again.

Then i found that in forums people suggest downloading all dependencies and pacman then extract them to root. Did it with again an error message:

Error while loading shared libraries: libalpm.so.7 - No such a file or directory

I checked with 'locate' command and there was libalpm.so.7. in the filesystem. How can i fix my pacman?

Plus i have this libpng-14 error nearly on everything so my computer now became  almost unusable. If i can fix pacman i think libpng wont be that hard.

Re: Broken pacman with the update.

I checked with 'locate' command and there was libalpm.so.7. in the filesystem.

First the 'locate' command doesn't look into the filesystem but into its database, generated by the 'updatedb' command ran generally as a cron task.
So if you just changed the filesystem, you have to run 'updatedb' manually yourself as root, to get the last state of the filesystem in the locate database.

Then what i did in this area i can not remember but i think i extracted pacman to the root then ...

You can see what you've done before using the 'history' command of bash.

people suggest downloading all dependencies and pacman then extract them to root. Did it with again an error message:...

You might have extracted the wrong pacman version.
Tell exactly what packages with their version you extacted manually into root.

libalpm.so.7 comes from pacman 4

So if you don't have it, you have used another pacman version.

Re: Broken pacman with the update.

Thanks for the answer berbae! This is my work computer, i have to fix it until tomorrow

I have extracted pacman- 4. But to clean the situation can i remove every instance of pacman in my filesystem and extract a new pacman-4 again?

Is there a command for removing pacman completely?

Re: Broken pacman with the update.

Did you compile something from AUR?

Try to remove this package and install from official arch repository.

pacman -Rd pacman

Using pacman to uninstall pacman is like pulling yourself up by your shoelaces.

In your case, undo what you've done to extract pacman in your root filesystem, ie remove all the files which were extracted.

I have extracted pacman- 4

You have to extract also the dependencies of pacman 4: libarchive>=3.0.2, maybe others, depending on what is already present in your system.
Read the wiki links given above and the referenced links cited inside.

This is my work computer, i have to fix it until tomorrow

If your system is up to date, your libpng-14 errors concern only the AUR packages needing to be re-built.
So you can use everything else for your work without pacman functioning yet.

When you will post again, be precise in your text: tell exactly what commands you used and the exact output of them on your screen.
Without that, it is very difficult to help you efficiently.

That was mean

@Paingiver, here you can check pacman dependencies. It may be a good idea to check everything is where it should be.
