In UM16.04 I am able to open an APK file using Archive Manager, but in UM18.04 I cannot. I think I have all available libraries installed. Any suggestions how I can unpack an APK in UM 18.04.
Found an answer on AskUbuntu here:
Short version: copy the .apk to .zip
Thanks. My error message is different, but the work around (not solution) works. It is odd that the same application works just fine opening APKs under 16.04. This is the second application I have come across that 18.04 broke (worked in 16.04 and not in 18.04).
I found a solution: Xarchiver
