This is not a bug in cartopy, matplotlib tries to use ImageTk but the
package is not installed.
python3-matplotlib only Recommends python3-pil.imagetk, this should be a
Depends.
This issue is still present in matplotlib (3.5.0-2) and affects several
packages. These should not have to add python3-pil.imagetk to their
build dependencies because matplotlib does not pull it in.
The attached patch moves the Recommends to Depends.
Kind Regards,
Bas
