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 can'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
```
In the command, {newfilepath} indicates the path to be backed up. Replace it with the actual path.
Open the /var/lib/dpkg/status file, locate the record of the software package that fails to install, and remove the record, as shown in the marked position in Figure 1.
```
vim /var/lib/dpkg/status
```
Figure 1 Software package record
Reinstall swig.
```
apt install swig
```
