Pacman's not telling me what's corrupt

[phillid]

I ran `pacman -Syu`, I have done many times before without fault, but today, I get an error message:

$this->bbcode_second_pass_code('', '
:: Proceed with installation? [Y/n]
(34/34) checking keys in keyring [##################] 100%
(34/34) checking package integrity [##################] 100%
error: failed to commit transaction (invalid or corrupted package)
Errors occurred, no packages were upgraded.
synchronizing filesystem...
')

That's literally the whole error message.
So I ran `pacman -Su --debug`:

I tried upgrading psmisc by itself `pacman -S psmisc` and it works fine, so it's not psmisc that's corrupt. It looks to me like a false positive, as no packages are actually corrupt.

I have manually upgraded pacman
I have manually upgraded glibc

What can I do next?

Cheers

Clear the cache and try again.
$this->bbcode_second_pass_code('', 'yes | pacman -Scc')

[phillid]

Is there anything I can do short of that? I'm stuck on extremely slow internet at the moment (~5 KB/s) so redownloading everything would be a pain.

Besides, it doesn't seem like a cache problem; pacman's fine installing the packages individually, but not when I do `-Su`.

[moonman]

I think your error is here:
$this->bbcode_second_pass_code('', 'debug: checking sha256sum for /var/cache/pacman/pkg/libpipeline-1.3.0-1-armv6h.pkg.tar.xz
debug: returning error 6 from _alpm_pkg_validate_internal : wrong or NULL argument passed')

[phillid]

Thanks for that -- I'd completely missed that when checking the output. What's odd is that libpipeline installed fine on its own while linux-firmware appeared to be corrupt. I think I've narrowed it down to the fact that my Pi and all my other computers (i686 machines) all dump into a shared pacman cache, meaning that they will (in theory) share the architecture-independent packages, however I'm guessing that if an i686 machine downloads such a package from its mirrors, it'll be signed with a key or slightly tweaked such that the arm box doesn't want to touch it. I'll have to have a look at importing the ArchLinux packagers' keys into the Pi and the ArchLinux ARM builder key into the i686 machines...

Cheers for your help.

EDIT: I've just done some digging, and of course, the signatures are stored in the repo database, so adding the keys won't solve anything. My solution will be to keep the i686 and armv6h caches separate.

[kmihelich]

It's not all about keys. The checksums for the package that our repo databases say are valid, which are what pacman is also checking, are not the checksums of x86 Arch packages, since they're not the exact same files, since this is a separate distribution.

[phillid]

Yeah that makes sense. I had just (naively) assumed that the -any- packages would be identical, but like I said, that was naive.
