Update Ubuntu/Debian t64 Year 2038 Linux package choices

[MikeMcC399]

Situation

The section Get Started > Install Cypress > System requirements > Linux Prerequisites > Ubuntu/Debian provides two sets of Linux prerequisite recommendations for Linux packages depending on whether the underlying operating system releases have been converted to support the Year 2038. Since the release of Debian 13 (Trixie), the labels for which implementation to use don't cover Debian 13.

Assessment

The following Ubuntu / Debian operating system releases are supported by Cypress

• Ubuntu 20.04 and above
• Debian 11 and above

The Ubuntu release cycle shows the following releases covered by standard support, with detailed information in the Ubuntu wiki releases page:

• Ubuntu 22.04 (Jammy Jellyfish)
• Ubuntu 24.04 (Noble Numbat)
• Ubuntu 25.04 (Plucky Puffin)

The Debian Releases includes the following releases within End of Life and End of Long Term Support that are also covered by Cypress support:

• Debian 11 (Bullseye)
• Debian 12 (Bookworm)
• Debian 13 (Trixie)

Ubuntu 24.04 (Noble Numbat) Release Notes section "Year 2038 support for the armhf architecture" explains that "packages have been updated to handle time using a 64-bit value rather than a 32-bit one"

Debian 13 (trixie) Release Notes states "All architectures other than i386 now use a 64-bit time_t ABI, supporting dates beyond 2038." In practice, Debian 13 automatically transitions to t64 packages if the old package names are used, so it is not necessary to use t64 names. This may be a consideration when cross-version compatibility is needed.

Operating system	pre-t64	t64
Ubuntu 20.04 (Focal Fossa)	✅
Ubuntu 22.04 (Jammy Jellyfish)	✅
Ubuntu 24.04 (Noble Numbat)		✅
Ubuntu 25.04 (Plucky Puffin)		✅
Debian 11 (Bullseye)	✅
Debian 12 (Bookworm)	✅
Debian 13 (Trixie)	✅	✅

Change

Add Debian 13 to the t64 section as optional.
