For me, the root cause actually turned out to be the same as an unrelated problem where git rebase interactive was hanging.

The culprit was good old BLODA COMODO. It was more obvious in that git problem because I saw high CPU usage from COMODO while git rebase -i was hanging.

However, turning off all of COMODO’s services/systems wasn’t enough to fix the problem. The workaround (discussed here, here, here, and here) turned out to be to go to Settings > Advanced protection > Miscellaneous > Don't detect shellcode injections in these applications and add File Groups > All Applications to the exclusion list.

After that, git rebase interactive and pacman worked properly.

Causes and solutions

This error can happen if there are conflicting gnupg installations in PATH. Try running pacman in a special shell like set PATH=, msys2_shell.bat.
MacType can cause this. Put gpg.exe and pacman.exe lines under the [UnloadDll] section of your .ini file under C:\Program Files (x86)\MacType\ini or C:\Program Files\MacType\ini.
Check BLODA.
It can happen when the upgrade process reported failures (fork errors). Use update-core for system upgrades and take care to follow the instructions.
Try re-installing ~~gpgme~~ libgpgme, gnupg and pacman packages (you can temporarily disable signature checking in /etc/pacman.conf).
Try removing /etc/pacman.d/gnupg, then pacman-key --init, pacman-key --populate msys2, pacman-key --refresh-keys.
Maybe autorebase.bat is sometimes needed even for 64-bit MSYS2.
Try debugging for GPGME by export GPGME_DEBUG=9 before running pacman ...something... 2> ~/gpgmelog and looking at the logfile ~/gpgmelog.

Had this issue due to MacType; adding pacman.exe and gpg.exe to [UnloadDll] solved my issue.

Yo quise compilar Super Mario 64 Plus en MSYS2 MINGW64 y me aparece esto: advertencia: No se ha encontrado el depósito público de claves; ¿ya se ha ejecutado «pacman-key --init»? error: Error de GPGME: Motor de cifrado no válido advertencia: No se ha encontrado el depósito público de claves; ¿ya se ha ejecutado «pacman-key --init»? error: Error de GPGME: Motor de cifrado no válido advertencia: No se ha encontrado el depósito público de claves; ¿ya se ha ejecutado «pacman-key --init»? error: Error de GPGME: Motor de cifrado no válido error: la base de datos «mingw32» no es válida (base de datos no válida o dañada (firma PGP)) error: la base de datos «mingw64» no es válida (base de datos no válida o dañada (firma PGP)) error: la base de datos «msys» no es válida (base de datos no válida o dañada (firma PGP))

Que debo hacer?

I use MSYS2 with ConEmu and was having this issue as well. Running pacman -Syu once in the msys2_shell.cmd seems to have resolved the issue and now I can run it inside ConEmu again.

Also, for MacType users, when you put following lines into your .ini file under C:\Program Files (x86)\MacType\ini or C:\Program Files\MacType\ini, GPGME will works properly.

[UnloadDll]
gpg.exe

To people who find a solution here, please leave a comment to let us know what worked for you if you wouldn’t mind. Thanks in advance.

For MacType users, if you have this problem even after adding gpg.exe under [UnloadDll], try adding pacman.exe also.

[UnloadDll]
gpg.exe
pacman.exe
