A number of Linux distributions, including Fedora, Slackware, Ubuntu, and Debian use xz for compressing their software packages. Arch Linux previously used xz to compress packages, [11] but as of December 27, 2019, packages are compressed with Zstandard compression. [12] Fedora Linux also switched to compressing its RPM packages with Zstandard ...
[13] [19] [20] GitHub disabled the mirrors for the xz repository before subsequently restoring them. [21] Canonical postponed the beta release of Ubuntu 24.04 LTS and its flavours by a week and opted for a complete binary rebuild of all the distribution's packages. [22] Although the stable version of Ubuntu was not affected, upstream versions ...
Debian packages can be converted into other package formats and vice versa using alien, and created from source code using checkinstall or the Debian Package Maker. [ 4 ] Some core Debian packages are available as udeb s ("micro debs"), and are typically used only for bootstrapping a Debian installation.
Some distributions like Debian tend to separate tools into different packages – usually stable release, development release, documentation and debug. Also counting the source package number varies. For debian and rpm based entries it is just the base to produce binary packages, so the total number of packages is the number of binary packages.
It is also capable of automatically installing the generated packages, and can try to convert the installation scripts included in the archive as well. Automatic installation should be used with caution since Linux distributions may vary significantly from one another, and using install scripts automatically converted from an Alien format may ...
Snap is a software packaging and deployment system developed by Canonical for operating systems that use the Linux kernel and the systemd init system. The packages, called snaps, and the tool for using them, snapd, work across a range of Linux distributions [3] and allow upstream software developers to distribute their applications directly to users.
In March 2018, Canonical tested [23] the use of zstd as a deb package compression method by default for the Ubuntu Linux distribution. Compared with xz compression of deb packages, zstd at level 19 decompresses significantly faster, but at the cost of 6% larger package files. Support was added to Debian (and subsequently, Ubuntu) in April 2018 ...
Support for LZO, [4] xz, [5] LZ4 [6] and zstd [7] compression was added later. The decompression routine is a negligible factor in boot time, and prior to the development of the bzImage , the size constraints of some architectures, notably i386, were extremely limiting, making compression a necessity.
