Geany 1.33 is a fairly old version, released before debugger was ported to gtk3. So it would not build with a GTK3 version of Geany and so it isn't in the geany-plugins the distro provides. I think its only 1.36 (ie the current release) plugins that includes a debugger thats gtk3 compatible.
Unless you can build it yourself you will have to wait for the distro to update it. -- You are receiving this because you are subscribed to this thread. Reply to this email directly or view it on GitHub: https://github.com/geany/geany-plugins/issues/957#issuecomment-590738035
