I am a new zynthian user. My Zynthian ran a standard “ZynthianOS “Aruk Stretch” RC-3”. Since Puredata was making no sounds with it I updated the OS via ssh to latest version. Now almost all LV2 synth are not getting loaded anymore and the triangle icon is poping up. I was not able to find any error log beside the UI-log which is showing no errors at all. What is going wrong here and where can I find a detailed error log?
