Weird Zip Problem

[LL-user]

bitsnpcs's suggestion might work IF only the path/filename is screwed up for any reason but not the content.
Definitely worth giving it a try to manually create the folder structure and rename the files accordingly.

Regarding the GUI for p7zip:

• In general I avoid installing software outside the repositories for security and stability reasons.
  
• If you still are inclined to give it a go, it's worth first checking the validity of the first comment pointing out that the library libwxgtk3.0-dev is not anymore supported on v16.x and above.
  

Hope that helps
