This is really weird, the same issue was opened in the past, and I decided to completely remove the pre-uninstall script: #644 (comment)

Where did you install Sniffnet from?

Where did you install Sniffnet from?

It was either from the Github releases, or the website (which seems to link to Github releases as well).

It is the latest version as well.

$ sniffnet --version
sniffnet 1.4.1

Did you also install a previous version of the app?
My doubt is that maybe it's calling the old uninstall script, before I removed it.

Nevermind, I believe I found where the problem is, and I'll come up with a solution for the next release
