I've kept this machine on 8.04, performing occasional updates. Stability wise, it has been great except that it seems to die every 3-6 months for no obvious reason, despite combining through log after log. It's dual core, has 2 GB RAM, 2x 1GB HDD configured with mdadm as RAID1. Primary packages are Apache2, Mysql, Postgresql, PHP. I first deployed Ubuntu server 8.04 on a production machine that has low usage requirements it's predominantly a "brochure-ware" level webserver with about 4/5 websites, which also acts as an offsite backup repository. I have to admit that I'm a long term Ubuntu fan, particularly on the desktop (Since Breezy). I stumbled upon this thread whilst googling "ubuntu server stability issues" - searching for answers to my own concerns regarding the stability of Ubuntu server. Debian stable truly is the Golden Standard for rock solid stability. In basic terms this means Ubuntu LTS being based upon the Debian Testing branch and even with Ubuntus attempts to stabilize and polish their testing packages after they're pulled, does not equal the immense development and maturity of Debian stable and the packages thereof. Now the LTS release is based mostly on Debian Testing which in Debian terms "represents the state of the upcoming stable release before it is actually considered stable" and although Ubuntu puts a lot of time and effort into making regular and LTS versions as stable as possible after the packages have been pulled from there respective Debian branches, LTS is still based on the Testing branch which in turn is still considered by Debian in its own branch to be not quite ready for Production use or anything approaching mission critical.Īnd Ubuntu's community of developers simply cannot compete on the same scope or level of Debian which is possibly the largest communal based software ever created. Ubuntu is released every six months and is based off of the Debian unstable branch which generally means overall newer and more up to date software but at the same time having the disadvantage of being considered basically "unstable" at least in an enterprise context. This is a key difference between Debian stable and Ubuntu LTS especially if your concerned about longevity, uptime, stability etc. To answer your question about Professional/Production use I think there are several key elements that have been addressed but there is one point I feel that is extremely crucial. When you have more than a handful of servers, or just some applications that can't afford any downtime for testing upgrades, or just don't have the time to spend a day/week testing upgrades, Ubuntu has a large advantage over debian. This means you should be able to deploy the latest LTS on a box and not have to worry about it not getting security updates (for supported packages) for years and years. There is no extra fee for the LTS version we make our very best work available to everyone on the same free terms. With the v12.04 Long Term Support (LTS) version you get 5 years support for both the Ubuntu Desktop and the Ubuntu Server. This makes it very unpredictable as you won't know when you need to upgrade until you know when the next stable will be finalised.Ĭompare that to a Ubuntu LTS release, desktop updates are very similar but for the server applications and kernel, you get a mammoth 5 years of support, regardless of any new LTS releases in that time:Ī new LTS version is usually released every 2 years. This could mean you get anywhere from 18 months to 18 years of support. Stable releases come out when they're ready. You should note that the debian cadence is not guaranteed. It is not possible to support three distributions supporting two simultaneously is already difficult enough. The security team tries to support a stable distribution for about one year after the next stable distribution has been released, except when another stable distribution is released within this year. So if a stable comes out every two years, and you started on a stable release right at its launch, you get three years of updates: I think the prime consideration and comparison between debian stable and an Ubuntu LTS is security and general package updates.ĭebian "stable" releases are supported for a year after the next stable release. And there are clearly some differences that are very relevant to deploying each. It's clearly a decision that lots of developers will want to weigh up before deploying. Well I don't see why people are making a fuss about the quality of the question.
