I needed to run sudo ldconfig in order for /usr/local/bin/convert -version to report back that Imagemagik was installed.

when i do ./configure it seems to be missing the GIF from the delegates. No matter what I do, even if gflib* is installed and the latest version of libvips is installed, it will complain. Ended up ditching sharp altogether and use FFmpeg instead. It's faster

I gave up on Ubuntu 20.04 for a similar reason with delegates after installing it twice on different Vm’s but it worked perfect on Ubuntu 18 on first install. Maybe give that a go!
