GPGME errors when using pacman

[lebgdu92]

Hello, I have been unable to update or install any program for some time. When I try to search for updates it gives me this.

sudo pacman -Sy
[sudo] Password for gabriel : 
error: GPGME error: No data
error: GPGME error: No data

error : GPGME error : No data

I’ve tried refreshing the gpg keys with sudo pacman-key --refresh-keys 2> ~/pacman-key-errors.log but the problem persists. The operation generated a lot of errors, which I’m attaching as a log file.

pacman-key-errors.log

I saw that there was a topic in which someone had exactly the same problem as me. I applied the proposed solution but still no difference.

"error: GPGME error: No data" when I'm trying to update

Looks like your local signatures are expired and/or invalid and are preventing you from installing the keyring and gnupg packages. It’s kind-of a catch-22: the local signatures need to be updated to function, but the signatures on the packages containing the required updates don’t match any valid local ones, and thus are prevented from installing. The fix is simple, but a bit of a security risk. The signatures are there to protect you against MITM (man in the middle) attacks. However, in order…

sudo pacman -Sy

… doesn’t search for updates

pacman -Syu does

I have been unable to update or install any program for some time.

Did you try to refresh your list of mirrors
before you try to update the system?

Your solution solved my problem of updating installations via pacman. But I still can’t update programs installed via AUR repositories.

sudo pamac update

sudo pamac update

Do not ever use sudo with pamac – only with pacman.

Simple solution.

Update using pacman:

sudo pacman -Syu

Update using pamac:

pamac update

With pamac, if elevated privileges are ever needed, it will ask you.

Using --force-refresh with the pamac command might help to overcome this issue:

pamac update --force-refresh

I hope this helps.

Cheers.

Aside:- Here’s a nice long command for updating your Manjaro system; it chooses the fastest pacman mirrors; performs an update using pacman; performs an update using pamac while forcing a refresh. Copy it to your notes:

sudo pacman-mirrors --fasttrack 5 && sudo pacman -Syu && pamac update --force-refresh

[lebgdu92]

Thank you very much. With the --force-refresh option, everything is back to normal. As for the use of administrator privileges with pamac, I take note. As for the mirrors, I’ve already been able to define the fastest one before, so there’s no need to do so.

@lebgdu92

As for the mirrors, I’ve already been able to define the fastest one before, so there’s no need to do so.

And when that mirror fails, for whatever reason, now you have an alternative method. Thanks for marking my post as the solution, however, I’ve reassigned it to the previous post from @Aragorn - which really solved your issue. All that my post added was a simple command you had probably forgotten.

Cheers.
