报错netplan command not found

The error "netplan: command not found" indicates that the netplan command-line tool is not installed on your system or it is not included in your system's PATH.

Netplan is a utility for managing the network configuration in Ubuntu systems. To resolve this issue, you can try the following steps:

Check if netplan is installed: Run the following command in your terminal:
```
dpkg -l netplan*
```
If netplan is not installed, you will need to install it. Use the following command to install netplan:
```
sudo apt install netplan.io
```
If netplan is already installed, try locating the netplan command by running the following command:
```
which netplan
```
If the command returns an empty output or a "command not found" error, it means that the netplan command is not in your system's PATH. You can try locating the netplan binary manually by running the following command:
```
find / -name 'netplan'
```
Once you locate the netplan binary, you can add its directory to your system's PATH by editing the ~/.bashrc file and adding the following line at the end:
```
export PATH="/path/to/netplan:$PATH"
```
Replace "/path/to/netplan" with the actual directory path where the netplan binary is located.
After making any changes, you need to reload the terminal or run the following command to apply the changes to your current session:
```
source ~/.bashrc
```

After following these steps, you should be able to run the netplan command without encountering the "command not found" error
