You also mentioned to use trace when opening app. This seems like a good suggestion which could give some info. How it is used? Do I just go sudo gainroot and then write "trace appdownloader"? And have to ask: without cssu appdownloader I can download apps. Is that called something else than appdownloader, like application manager or something? Just wanting to be sure what to trace when I get to know how to trace. EDIT: tried 'trace appdownloader'. Result: /bin/sh: trace: not found EDIT: installed strace and tried 'trace appdownloader' but not found. I must do something wrong. And now the application manager installed appdownloader without errors but it still crashes. There drops the processor out first and after a short moment it crashes. What repos should I have on? After these I may ask more.
