[SOLVED] Reinstall corrupted package

Hello,
I just recovered my system after the laptop shutdown while updating.
Everything looks almost fine after I ran `pacman -Syu` again in the arch-chroot.

My problem is that pacman complains about one package and
I would not like to do anything wrong with pacman again...

$ pacman -Dk mono
error: 'mono-5.20.1.19-1': description file is missing
error: 'mono-5.20.1.19-1': file list is missing

$ pacman -S mono
error: failed to open /var/lib/pacman/local/mono-5.20.1.19-1 
warning: metadata for package mono-xx could not be totally loaded
error: failed to prepare transaction (invalid or corrupted package)

$ pacman -Syu
... there is nothing to do

What is the right way to fix this? Thanks

Re: [SOLVED] Reinstall corrupted package

Try recreating the database entry for that package.

pacman -U --dbonly /var/cache/pacman/pkg/mono-5.20.1.19-1-x86_64.pkg.tar.xz

Re: [SOLVED] Reinstall corrupted package

Hmm produces quite the same output as `pacman -Sy mono`

EDIT: I didn't do that

Re: [SOLVED] Reinstall corrupted package

In that case, manually remove what remains of the old database entry:

rm -r /var/lib/pacman/local/mono-5.20.1.19-1

Then recreate the database with pacman -U.

Also, once you've recreated the db entry, finish that upgrade.

pacman -Syu

Re: [SOLVED] Reinstall corrupted package

`pacman -Sy mono`

Don't do that: it breaks things.

Sorry, that was a lapsus: `pacman -S mono`.
Exactly what I want to avoid

Then recreate the database with pacman -U.

`pacman -U mono` yields

error: 'mono': could not find or read package 

Shouldn't I try `pacman -S mono` now instead?

Re: [SOLVED] Reinstall corrupted package

No, I meant re-run

pacman -U --dbonly /var/cache/pacman/pkg/mono-5.20.1.19-1-x86_64.pkg.tar.xz

pacman -S will fail because you have untracked files that belong to the mono package.

Re: [SOLVED] Reinstall corrupted package

Ok thanks, this worked
Don't know why `pacman -Syu` produced a whole lot of warnings about older versions of mono... but all seems in order now

Cheers!
