From cb12f776329a4d5b1c4c3600526eed1884d4135d Mon Sep 17 00:00:00 2001 From: "Kelvin M. Klann" Date: Thu, 26 Mar 2026 16:32:18 +0000 Subject: [PATCH] docs: recommend .deb or building from source on debian/ubuntu (#7110) Most recent releases: * firejail 0.9.72: 2023-01-16 * firejail 0.9.74: 2025-03-24 * firejail 0.9.76: 2025-07-30 * firejail 0.9.78: 2026-01-03 * firejail 0.9.80: 2026-03-14 firejail 0.9.76 was released over 6 months ago, but the packages from both Debian stable (13 / Trixie) and the Ubuntu PPA appear to still be on firejail 0.9.74, which is over 1 year old[1] [2]. As for installing firejail through Debian backports, it is unclear to me if that is currently working and if so, which firejail version would be installed on each Debian version. Lastly, the packages on Ubuntu seem to still be on firejail 0.9.72, which is over 3 years old, even on the latest Ubuntu 25.10 and on the upcoming Ubuntu 26.04[3]. So to avoid bugs and bug reports caused by old firejail versions, recommend either installing the release .deb file from GitHub or building from source on Debian/Ubuntu. Relates to #6842 #7060.
