Removed /usr/lib

Nibble · 2010-06-27 19:30:14

Hello!
I accidentally removed /usr/lib from my system. I got my hands on enough files to get pacman working again(thankfully). But now I need to reinstall every package on my computer to make sure that each and every file exists that needs to exist.

This has to be done before I reboot so I do not miss any critical files.

Any suggestions? Installing them manually will take a long, long time.

I didn't have this case yet, but maybe try the pacman -k opption (check if given package is missing files, if no package specified checks all, is what the manpage says) to see which packages are affected?

Never done this before. You could grab a list of all packages with

pacman -Qs | grep local | cut -d'/' -f2 | cut -d' ' -f1 > installed_packages

and then reinstall them with

sudo pacman -S `cat installed_packages`

But this would fail if there are packages installed which are from the AUR. They should be removed from the list somehow.

There's a forum post or wiki article which describes soemthing like this:

 comm -13 <(pacman -Qmq | sort) <(pacman -Qq | sort) > ~/pkglist

then

 cat pkglist | xargs pacman -S --needed --noconfirm

Please do a forum search before trying this as I don't remember where I first found it.

Thanks!
That worked, but there are still lots and lots of packages, any idea how to reinstall all these?

Didn't see previous post when I posted this one. Will look into that.

You can list your aur packages with "pacman -Qqm". Hope this helps.

It's also a good idea to run

pacman -Qk | grep ^warning:

as root.

Seems to be working now, will wait for reboot until I mark it solved.

No sort,

 LC_ALL=C comm -23 <(pacman -Qq) <(pacman -Qmq)

No cat,

xargs pacman -S --needed --noconfirm < pkglist

And pacman doesn't have ARG_MAX,

pacman $(for i in {1..999}; do echo -h; done)

so no xargs either.

pacman -S --needed --noconfirm $(< pkglist)
