I am working on the Xubuntu LTS Upgrade From 22.04 To 24.04. The process went very smoothly. However Wine did not automatically work without a hitch.

At first after the LTS Upgrade, when I would run an Application that uses the Wine architecture, nothing would appear to happen. I looked up the Launcher Command for a simple application that uses Wine:

And that way I could see an error message coming back from Wine:

I then went looking, and found many suggestions to just merely wipe out my:

However, according to this page:

"How to create new Wine prefixes on Linux"
https://www.addictivetips.com/ubuntu-linux-tips/create-wine-prefixes-on-linux/

A Wine prefix (AKA a Wine bottle) is a special folder in which Wine places all Wine-specific files, installed Windows programs, libraries and registry code, and even user preferences in.

Usually, a user only has one Wine prefix. This prefix is the ~/.wine folder.

Since my Xubuntu installation has always been 64-bit. I was very puzzled how after the LTS upgrade from 22.04 to 24.04 suddenly the Wine environment had reverted back to 32-bit mode. Several years ago. Wine in one of its updates that refreshes the Wine prefix had reorganization directories within that prefix to have the following segregated directory structures:

Back then, seeing this distinction, I reorganized my Windows program files I was running through Wine, segregating the 32-bit Windows programs under "Program Files (x86)" and the 64-bit Windows programs under "Program Files". So I turned to Synaptic to see what sorts of Wine packages were installed after my upgrade to Xubuntu 24.04.

I quickly located a package which had not gotten installed, named simply:

I added that package. and found that with that package added, it cured the original Wine error message I had found, the first time brought up the "Updating Wine Profile" dialog I had remembered seeing, and indeed successfully runs the Windows application.

Summary:
After LTS upgrading to Xubuntu / Ubunut 24.04 and if applications which use Wine to run on Linux will not start, try adding package "wine64" to see if that remedies your difficulties.

Do not... NO NOT! scorch Earth and remove all of your ~/.wine/ directory structure as many Internet posts suggests. Try this first!
