An error occurred while updating the Software Package Manager.

The Deb package of secondlife was downloaded last night. It was found that the package was installed on a network,
But the speed on my side is really...
No way. After several minutes of installation, the installation will be canceled, but after the installation is canceled,
The progress window is lost, but the window of the software package cannot be closed.
If you want to go to bed, just shut down the machine.
Unexpectedly... After the device is started up tonight, an update is displayed. Then, the update manager is displayed:
E: the package secondlife-install needs to be re-installed, but I cannot find the corresponding installation file.

This dialog box.
Click OK and the update manager is closed.
The same is true for new users.
I tried to reinstall the software package, but said the software package was damaged. I re-installed it, and the result is still the same> _ <
The aptitude command does not work either. It indicates that an error occurred while processing dpkg. Dizzy...
I searched Google for more than half a minute and finally found the solution:

$ Sudo gedit/var/lib/dpkg/status

After opening the file, find the relevant information and delete it. Of course, you 'd better back up the file beforehand.
After that, start the new version, haha... The world is quiet...
