Captcha broken with latest Debian-Buster ImageMagick package (8:6.9.10.23+dfsg-2.1+deb10u)
With latest ImageMagick package, Captcha is broken:
# dpkg -l | grep libimage-magick
ii libimage-magick-perl 8:6.9.10.23+dfsg-2.1+deb10u2 all Perl interface to the ImageMagick graphics routines
ii libimage-magick-q16-perl 8:6.9.10.23+dfsg-2.1+deb10u2 amd64 Perl interface to the ImageMagick graphics routines -- Q16 version
Downgrading the packages is the current workaround:
# apt install libimage-magick-perl=8:6.9.10.23+dfsg-2.1+deb10u1 imagemagick-6-common=8:6.9.10.23+dfsg-2.1+deb10u1
