Running Kubuntu 24.04.1 very new hardware.
3.7 worked well.
3.7.1 cannot find lv2 and lsp plugins. (Same with flatpak and appimage.)
The plugin manager says they are to be here:
/usr/lib/vst/lsp-plugins/lsp-plugins-vst2-1.2.14.so
But they are not.
Not critical for me. I am super happy with Audacity. Just helping the community.
