What is the output of

pacman -V

When I run the specified command, I get a different result from you:

$ pacman -V|sed -r 's#[0-9]+#c65#g'|md5sum|cut -c1-6
56ad1b

(No, this result won't work, since the sed replacement regularly changes.)

everything looks fine to me, you have the wrong answer

To clarify why I am asking, the current captcha doesn't care what your version of pacman is, but it does require that pacman is not built with --enable-git-version (so, using pacman-git from the AUR would yield the wrong results).

My pacman-git build does not produce the *same* incorrect answer as you, so if you are using pacman-git you're not using the same build as me.

The output of "pacman -V" is:

$ pacman -V

Aha, try LC_ALL=C ;)

Got it! It seems your CAPTCHA generator assumes LANG has been set to en_EN.UTF8:

[p@p ~]$ export LANG=en_EN.UTF8
[p@p ~]$ pacman -V

I believe the captcha generator should at least mention that LC_ALL=C is required.

Already got there before you. ;) https://lists.archlinux.org/pipermail/aur-dev/2019-September/004679.html
