The 18.04.1 LTS is finally here, and it comes bearing a hoard of benefits for its users. This model is valid for five years and will be in use up to April 2023 when another release will come onto the market. Users of previous models are free to improve their OS’s to this, or they can opt to use the OS models which they have been using, based on their wishes.

Downloading 18.04.1 LTS

Users can access downloadable images from locations accessible to them, to allow them to improve from their current models. Here are a few ways in which users can go about this:

From 16.04.LTS or 17.10

Users using a desktop system can follow the following guidelines: Improving is as smooth as a few simple steps.
  • Start by going to the system settings from where you will find an option on ‘Software and Updates.’ Open this option and select the tab that reads ‘Updates.’ At this point, you will see a drop-down menu on notifications regarding any Ubuntu models that are new on the market. If you are using the 16.04, select ‘any new models.’ For users of the 17.0, choose ‘for long-term underpinning models.’
  • At this point, hold on to the Alt+F2 keys and type into the command box: update-manager –c. This manager will open up and indicate that the Ubuntu 18.04.1 LTS is available to you. You can then click on improve and follow the instructions on the screen.
  • The server system process is quite similar to that of the desktop and users should have no problem with this.
  • It is essential that users note that there are no offline ways in which they can improve their systems. As such, ensure that you have a stable connection to an official mirror before starting the improve process.

Security features

In the Ubuntu 18.04.1 LTS, the gcc is such that it can compile applications as PIE, alongside direct binding. This improvement will ensure that the ASLR gets used at an optimum, as opposed to earlier models. Most packages will take advantage of this. Other added features include an improved desktop interface, ease of installation of PPA apps, quick capture of screenshots and screencasts and more speed.

This model will run Ubuntu Core, Desktop and Server, with underpinning for five years. On Studio 18.04, the underpinning will last for nine months while other flavors will enjoy underpinning for three years. Improving to the 18.04.1 LTS will hugely benefit users regarding security, access to more apps and an increase in the number of ways one can use their desktop.
