I want to use LTspice on my Ubuntu 20.04 LTS.
But it is not available for Ubuntu, so my Professor suggested me to download Wine.

I did all the steps as mentioned in <https://wiki.winehq.org/Ubuntu>.

However in the last step, when I type `sudo apt install --install-recommends winehq-stable`

I am getting this error :

```
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 winehq-stable : Depends: wine-stable (= 5.0.2~focal)
E: Unable to correct problems, you have held broken packages.

```

How can I resolve this?
