WFM, Linux Mint 19.1 == Ubuntu 18.04 LTS IIRC. Geany 1.37 (git >= 82590af4), en_AU.UTF-8 GTK 3.22.30, GLib 2.56.4 and Geany-plugins at https://github.com/geany/geany-plugins/commit/c156641259643ef4e32d067dd0b346....
@Nefor111 we are not responsible for the Arch packaging, ask there. For the self builds, you need the appropriate _development_ package of VTE, and specifically 2.91 for GTK3.
@manastalukdar as noted above debugger needs VTE and that library is not available on windows AFAIK.
