Issue: kdevelop! -s "{83d630dc-ad24-4b81-9a5c-e85d3c855120}" The program 'kdevelop!' is currently not installed. You can install it by typing: Problem: KDevelop cannot find kdevelop! (since /usr/bin from AppImage mount is not in PATH). Suggestion: plugins/konsole/kdevkonsoleview.cpp 71: interface->sendInput( " kdevelop! -s \"" + KDevelop::ICore::self()->activeSession()->id().toString() + "\"\n" ); => Use a relative path to the current executable, e.g.: qApp->applicationPath()/../kdevelop!
