"Writing more data than expected" while snapping an ros project
Metadata
Current evaluation
User on snapcraft 2.43.1 hit an apt FetchError ('Writing more data than expected') pulling catkin/ROS deps. No maintainer response in ~8 years; the error is an apt cache/mirror issue and the affected version is long EOL.
Suggested action: close stale
Reason: The issue is ~8 years old with 0 comments and no maintainer interaction, and reports an apt-level FetchError ('Writing more data than expected') on snapcraft 2.43.1 — a transient apt cache/mirror problem surfaced by snapcraft, not a snapcraft defect. The affected 2.x version and the catkin plugin code paths in the traceback (snapcraft/plugins/catkin.py, snapcraft/internal/repo/_deb.py) no longer exist in modern snapcraft, so it is no longer applicable.

Issue body
I was tring to package and deploy a ROS project as a snap.And it turn out the following error.
The project(https://github.com/felixendres/rgbdslam_v2) is working alright on my computer,and what I simply did is "snapcraft init",change the yaml,"snapcraft",strictly folowing this tutorial just with anthor project http://wiki.ros.org/ROS/Tutorials/Packaging%20your%20ROS%20project%20as%20a%20snap
and it went wrong...
