CTOnews.com August 26, Canonical developer and OpenPrinting project leader Till Kamppeter said in May this year that he plans to use the Snap version of the CUPS print stack by default on Ubuntu 23.10 (Mantic Minotaur).

But after months of testing, officials abandoned the decision. Ubuntu 23.10 (Mantic Minotaur) and Ubuntu 24.04 LTS distributions still use the DEB-based print stack by default.

The team has postponed the effective date and plans to switch to the snap version of the CUPS print stack by default in Ubuntu version 24.10.

Ubuntu 23.10 developer version has added the snap version CUPS print stack, but many problems were found during the test. CTOnews.com is simply listed here:

The snap CUPS print stack is not fully ready to be embedded in the desktop distribution.

Snap version CUPS print stack does not work in some Ubuntu flavor versions

GNOME Control Center needs to adjust UI to snap version of CUPS print stack

D-Bus sessions need improved support

Snap is a new generation of linux package management tool proposed by Canoncial, which aims to unify the package format on all linux distributions and achieve "one package, use everywhere".

At present, Snap can be used on many Linux distributions, including Ubuntu, Fedora, Mint, and so on. The Snap application runs in a sandbox, and the system implements its security features by restricting the access of the application to resources through some mechanisms.

Snap has the following advantages over the traditional deb format:

Dependency management: the Snap package has all the runtime and dependency libraries built into it, so it can run on any version of the Ubuntu distribution without having to worry about dependencies.

Version control: the Snap format allows developers to package different versions of software into different Snap packages, which allows users to install different versions of the software at the same time without interfering with each other. This is also useful for developers because they can test different versions of the software in different Snap packages.

Security: Snap format provides a sandbox mechanism that can limit software access to the system, thereby improving the security of the system. This mechanism enables users to install and use the software more safely without having to worry that the software will endanger the security of the system.

Easy to maintain: the Snap format allows developers to automatically update the software to the latest version, which makes it easier for users to keep the software up-to-date.
