This package contains a utility for analysis of running processes belonging to snaps that use classic confinement. Classic confinement does not isolate the snap from the host (or the host from the snap) and doesn't use a mount namespace to ensure only the packaged shared libraries are used.
Because of this characteristic such snaps are prone to packaging bugs where the application only happens to work on a given machine because a critical dependency is unknowingly provided by the host.
This snap inspects the running snap application and reads the segments mapped into the process address space. Files mapped from /snap/core/ and /snap/$SNAP_NAME/ are ignored as they are exactly what correctly packaged applications should do. All other file segments are reported because they are used from the host directly and can thus break in the future.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
If you’re running Ubuntu 16.04 LTS (Xenial Xerus) or later, including Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 20.04 LTS (Focal Fossa), you don’t need to do anything. Snap is already installed and ready to go.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install Classic snap analyzer, simply use the following command:
sudo snap install classic-snap-analyzer --classic
Browse and find snaps from the convenience of your desktop using the snap store snap.
