SOLVED: /etc/pacman.d/gnupg/pubring.gpg 0 bytes can't install anything

luser · 2023-02-25 00:52:32

I have no idea how this happened, but my pubring.gpg file size is 0. When I try to revert to my last archlinux-keyring as follows:

sudo pacman -U archlinux-keyring-20230130-1-any.pkg.tar.zst

I get this result:

loading packages...
error: 'archlinux-keyring-20230130-1-any.pkg.tar.zst': invalid or corrupted package (PGP signature)

So, I can't install anything, because pubring.gpg is blank.

$ pacman-key --init

and

$ sudo pacman-key --populate archlinux

don't help either.

How do I solve this?

Well, being an impatient human, I monkeyed around with it, performing the following steps, which seems to have resolved the issue:

# rm -r /etc/pacman.d/gnupg/
# pacman-key --init
# pacman-key --populate archlinux

This appears to have resolved my problem. Frankly, I was afraid to

rm -r /etc/pacman.d/gnupg/

However, Pacman seems to work now. If anyone believes that there was a better way to resolve the issue, please chime in.

@Jason

I tried the things in your link:

# pacman-key --init
# pacman-key --populate

While the first line seemed to work, the latter produced the following output:

==> Appending keys from archlinux.gpg...
==> Disabling revoked keys in keyring...
  -> Disabled 34 keys.
==> Updating trust database...
gpg: public key of ultimately trusted key E645B197910C1332 not found
gpg: marginals needed: 3  completes needed: 1  trust model: pgp
gpg: depth: 0  valid:   2  signed:   5  trust: 0-, 0q, 0n, 0m, 0f, 2u
gpg: depth: 1  valid:   5  signed:  95  trust: 5-, 0q, 0n, 0m, 0f, 0u
gpg: next trustdb check due at 2023-07-12
==> ERROR: Trust database could not be updated.

. . . and it didn't solve the problem, so I tried:

$ sudo pacman-key --populate archlinux

which didn't produce an error, BUT, it didn't solve the problem either. Immediately after, I tried reinstalling the archlinux-keyring. . .

$ sudo pacman -S archlinux-keyring

So, that didn't work, either.

At this point, I'm just wondering whether there was any cost to deleting /etc/pacman.d/gnupg that I am unaware of. Running pacman-key --init and pacman-key --populate without deleting the folder didn't get the job done.

Remove or reset all the keys installed in your system by removing the /etc/pacman.d/gnupg directory (as root) and by rerunning pacman-key --init followed by pacman-key --populate to re-add the default keys.
