try building paru-git instead

[ssuukk]

That helped, thanks!

The main issue here is that paru should be built with --features generate if the architecture isn't x86_64, since there's a good chance that the version of pacman built for those architectures isn't the same as the libalpm version paru is built with by default.

See these comments on the AUR package: https://aur.archlinux.org/packages/paru#comment-994933

Would be greatly appreciate if the AUR package were updated!

Dear all,

I was able to build paru on my RPi4 running ARMv7 with the below changes to the PKGBUILD file. Before I have seen the same error message. (Inspired by: https://github.com/Morganamilo/paru/issues/1154 )

Until here the first packages installed through paru are installing and working fine.
