Are you trying to operate on the file which fails to download?

hi

I am working on the latest package “16.10.3 native”
after updating to latest package, I have created new application, It is referring toolchain “_corrupted_0_legato.toolchain.1.7.3.SWI9X15Y_07120900-wp85-wp750x-native-x86_64-201705021320”

why its name is corrupted?
and is this root cause of the issue?

Hi,

This (“corrupted” directories) may happen when installed packages have some troubles to be loaded.
Maybe you could give a try to clean your packages folder and re-install.
But I don’t think this could be the root cause for your troubles, since when you’re building an app that is referencing libs, libs are used from the target filesystem (and not bundled from installed toolchain directory).
