What Should I Do If the swig Dependency Package Cannot Be Installed?

If the swig dependency package fails to be installed during TF Serving build, the error message shown below is displayed:

E :The package ascend-cann-toolkit needs to be reinstalled, but I cant`t  find an archive for it.

Perform the following steps to reinstall the swig dependency package:

Back up /var/lib/dpkg/status.
```
cp /var/lib/dpkg/status /{newfilepath}/status
```
{newfilepath} indicates the path to be backed up. Set it based on the actual situation.
Open the /var/lib/dpkg/status file, locate the record of the software package that fails to install, and remove the record. Figure 1 is an example of software package records.
```
vim /var/lib/dpkg/status
```
Figure 1 Software package record
Reinstall swig.
```
apt install swig
```
