Is your feature request related to a problem? Please describe.

To add an uninstall script for the packages. it would help us ease the process of implementing the soft-reset feature.

Describe the solution you'd like

To create an uninstall script.

Describe alternatives you've considered

We can either delete all packages from the package from a soft-reset daemon itself or create a separate script. I would recommend deleting it from the same file.

@mariobehling @Orbiter @hongquan @cweitat , your suggestions?

[hongquan]

Actually, I want the "reset" to be implemented by packaging the susi_linux as deb or snap package. We will be able to solve many issues with this: factory reset, soft reset, automatic update, uninstall.

So, every implementation which we did until now: deliver a copy of susi_linux in tarball and use it for factory reset, use git to fetch the source code... all are dirty quirks. We should not continue that path.

Don't write the uninstall script now, it is still a quirk as other ones. If you have time, please invest in the deb/snap direction.

Okay @hongquan , I will try to look into packaging. Do you know of any good place to start reading?

Sorry, there is no good tutorial. I used to do it some years ago, but my knowledge may be outdated.

And before packaging, we need to redefine the app structure. Cannot let the app running inside /home/pi like now. More things to concern, I already mentioned somewhere in GitHub issues.
