Hi, today I read the complete thread. Firefox is indeed installed by default for most, if not all Ubuntu flavours. However, updating from command line isn't explained correctly. To upgrade the complete install by command line, including firefox, you need to run
sudo apt update # to download information about available updates sudo apt full-upgrade # to install the available updates It make perfect sense to upgrade the complete install on a daily basis, while it doesn't matter, if Firefox upgrades aren't available by Ubuntu repositories, in the same minute upstream released them. In a nutshell, I try to avoid technical language: Usually Ubuntu doesn't provide new releases from upstream within an Ubuntu release at all. Usually it stays with a software version and upgrades only add important changes to those versions. Firefox is an exception. Note, some software will never receive an upgrade: "Main The main component contains applications that are free software, can be freely redistributed and are fully supported by the Ubuntu team. This includes the most popular and most reliable open-source applications available, many of which are included by default when you install Ubuntu. Software in main includes a hand-selected list of applications that the Ubuntu developers, community and users feel are most important, and that the Ubuntu security and distribution team are willing to support. When you install software from the main component, you are assured that the software will come with security updates and that commercial technical support is available from Canonical. Restricted Our commitment is to only promote free software – or software available under a free licence. However, we make exceptions for a small set of tools and drivers that make it possible to install Ubuntu and its free applications on everyday hardware. These proprietary drivers are kept in the restricted component. Please note that it may not be possible to provide complete support for this software because we are unable to fix the software ourselves - we can only forward problem reports to the actual authors. Some software from restricted will be installed on Ubuntu CDs but is clearly separated to ensure that it is easy to remove. We will only use non-open-source software when there is no other way to install Ubuntu. The Ubuntu team works with vendors to accelerate the open-sourcing of their software to ensure that as much software as possible is available under a free licence. Universe The universe component is a snapshot of the free, open-source, and Linux world. It houses almost every piece of open-source software, all built from a range of public sources. Canonical does not provide a guarantee of regular security updates for software in the universe component, but will provide these where they are made available by the community. Users should understand the risk inherent in using these packages. Popular or well supported pieces of software will move from universe into main if they are backed by maintainers willing to meet the standards set by the Ubuntu team. Multiverse The multiverse component contains software that is not free, which means the licensing requirements of this software do not meet the Ubuntu main component licence policy. The onus is on you to verify your rights to use this software and comply with the licensing terms of the copyright holder. This software is not supported and usually cannot be fixed or updated. Use it at your own risk." - https://help.ubuntu.com/community/Repositories#Main Regards, Ralf -- xubuntu-users mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/xubuntu-users
