What are Ubuntu LTS acronyms
The acronym LTS for Ubuntu means Long Term Support , which translated into Spanish would be something like Long Term Support . This means that those versions of Ubuntu will continue to receive new security updates and improvements. The period in which an LTS version receives updates is 3 years (the usual support is 18 months). Thus the support for the latest LTS version at the time of writing the article (Ubuntu 12.04 LTS) is extended until 2017.
Advantages of using LTS version on servers.
Ubuntu is increasingly used as an operating system for servers and in this type of configuration security is critical. With the LTS versions, security patches are maintained for 3 years, so these versions are the right choice when configuring servers.
Another advantage is that many application developers only keep packages updated for LTS versions. An example that happened to me a few days ago was with the Varnish web accelerator, I was about to install it in Ubuntu version 12.10 Quantal Quetzal and it turns out that Varnish developers themselves only support LTS versions.
Advantages of using LTS version in companies.
Some of you will know that Ubuntu is constantly updated and new versions come out quite frequently. These new versions usually solve errors or introduce improvements in the operating system, but in some environments, such as companies, the process of upgrading to a new version of Ubuntu can be tedious or even if compatibility with some third-party programs is lost. . This is why many companies choose the LTS versions as they guarantee support for at least 3 years.
Disadvantages of the LTS versions of Ubuntu.
The biggest disadvantage is not having the news introduced by recent versions that are not LTS. In my opinion this disadvantage affects especially when using Ubuntu as a desktop operating system, in these cases I think it is preferable to have the latest version installed instead of an LTS version.
In summary, it could be said that for servers or companies, the LTS versions are the most suitable but for a non-desktop PC. This is always very general as there may be very specific situations in which the use of an LTS version is recommended or not, so I invite you to comment using the comments.
