The change
Canonical has decided to convert one of Ubuntu’s core packages from its traditional Deb format to a Snap. The move retires the Deb version entirely once the transition completes. The only benefit cited is a modest increase in security that comes from the confinement rules Snaps apply by default.
Background on the formats
Debs have been the standard packaging method for Debian and its derivatives, including Ubuntu, for decades. They install files directly into the system and rely on the distribution’s dependency resolver. Snaps arrived later as a container-like format that bundles libraries and runs under a set of access restrictions enforced by AppArmor and other kernel features. Until this decision, both formats could coexist for the same component. The new policy ends that overlap for this package and designates the Snap as the sole supported option on Ubuntu systems.
Technical detail available
The announcement points to sandboxing as the reason for the switch. Snaps limit the files, network ports, and devices a program can reach without additional explicit permissions. No performance measurements, startup-time comparisons, or compatibility matrices appear in the report. The package itself is described only as “core,” which indicates it is installed by default or required by many common workflows, yet its exact name and function are not disclosed in the coverage.
Systems that receive updates after the change will pull the Snap instead of the Deb. Administrators who maintain local mirrors, pin specific package versions, or run scripts that inspect Deb metadata will need to update their tooling. No schedule for the removal or list of affected Ubuntu releases is provided.
Reactions so far
No statements from other distribution maintainers or from package maintainers outside Canonical have surfaced. The report contains no counter-arguments or alternative proposals, so the decision stands as presented.
Why it matters
The move shows Canonical continuing to steer its flagship distribution toward Snaps even when the stated security gain is described as slight. For day-to-day users the practical effect is small at first: one more process runs under confinement and one fewer Deb appears in apt output. Over successive releases, however, the cumulative result is a shrinking set of components managed by the classic package tools. Scripts that assume every installed file came from a Deb, monitoring agents that track dpkg status, and custom repository setups all require adjustment. The sandboxing itself only protects against what the confined program is allowed to do; without knowing the package’s purpose, it is impossible to judge whether the restriction blocks a realistic attack path or merely adds another layer of configuration. In short, the change trades a familiar, scriptable installation method for a more restricted runtime whose benefits remain narrowly defined in the current announcement. Administrators who value explicit control over the base system now have one more reason to track Canonical’s packaging roadmap closely.
