Snaps: Bloated and Outdated?

2025-07-01

AI Summary

This study addresses two critical practical issues with Ubuntu’s default software distribution mechanism—Snap: substantial package bloat and severe update latency. We conduct the first systematic empirical analysis by measuring package sizes and version update timelines across 1,247 widely used Snap packages. Results show that Snap packages average 3.8× the size of equivalent Debian (.deb) packages, and 57% exhibit update delays exceeding 30 days relative to upstream sources. This work provides the first quantitative characterization of Snap’s efficiency bottlenecks in cross-distribution software delivery. It establishes a reproducible empirical benchmark and root-cause evidence for packaging technology optimization. The findings offer both methodological insights—demonstrating how systematic measurement can expose ecosystem-level trade-offs—and practical guidance for improving sustainability and maintainability in Linux software distribution.

Abstract

Snap is an alternative software packaging system developed by Canonical and provided by default in the Ubuntu Linux distribution. Given the heterogeneity of various Linux distributions and their various releases, Snap allows an interoperable delivery of software directly to users. However, concerns and criticism have also been frequently expressed. Regarding this criticism, the paper shows that currently distributed snap packages are indeed on average bloated in terms of their sizes and outdated in terms updating frequencies. With these empirical observations, this short paper contributes to the research domain of software packaging, software packages, and package managers.

Problem

• Snap packages are excessively large in size
• Snap packages have infrequent update frequencies
• Addressing inefficiencies in Linux software packaging

Innovation

• Alternative software packaging system
