I have a problem to add an application like 7zip. I would like to install this application to read rar files. So I hope you can help me.
So I am going to explain the problem now:
First I'm searching for the application and to apply it after i applied, an error is coming on my screen:
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.
That's my problem and I hope you can help me. I'm not so good in these things so if you help me, explain it please in all steps.
