Things You Should Know About Ubuntu 18.04


Just for the sake of clarity, some of the answers here are influenced by my personal opinion. If you are an experienced/aware Ubuntu user, some of the questions may sound silly to you. If that is the case, ignore these questions.

Can I install unity on Ubuntu 18.04?

Yes, you can.

Canonical knows that there are people who just loved unity. This is why it has created Unity 7 available in the Universe repository. This is a community edition maintained and Ubuntu does not develop it directly.

I recommend using the default GNOME first and if you really can’t tolerate it, then go on installing unit on Ubuntu 18.04.

Which GNOME version does it have?

At the time of release, Ubuntu 18.04 has gnome 3.28.

Can I uninstall Vanilla gnome on it?

Yes, you can.

Existing GNOME users may not like the unit resembles, custom GNOME desktop in Ubuntu 18.04. There are some packages available in Ubuntu’s main and universe repositories that allow you to install vanilla gnome on Ubuntu 18.04.

Is the memory leak in gnome fixed?

Yes. The infamous memory leak in GNOME 3.28 has been fixed and Ubuntu is already testing the fix.

Just to clarify, the memory leak was not caused by Ubuntu. It was/will affect all Linux distributions that use Gnome 3.28. A new patch was released under Gnome 3.28.1 to fix this memory leak.

How long will Ubuntu 18.04 be supported?

It’s a long-term support (LTS) release and like any LTS release, it will be supported for five years. Which means that Ubuntu 18.04 will get the security and maintenance updates until April 2023.

Ubuntu 18.04 LTS will be released on April 26th. All participating flavors like Kubuntu, Lubuntu, Xubuntu, Budge, mate etc will have their 18.04 release available on the same day.

It seems Ubuntu Studio will not 18.04 as LTS release.

16.04 with unit to Ubuntu 18.04 with Gnome?

Ubuntu 18.04

If you are using Ubuntu 16.04, make sure in Software & updates – > Updates, the ‘ Notify me of a new Ubuntu version ‘ is set to ‘ for long term support versions ‘.

Ubuntu 18.04

You should get system notification about the availability of the new versions. After that, upgrading to Ubuntu 18.04 is a matter of clicks.

Even if Ubuntu 16.04 was unit, you still upgrade to Ubuntu 18.04 Gnome.

When will I get to upgrade to Ubuntu 18.04?

If you are using Ubuntu 17.10 and have the correct update settings in place (as mentioned in the previous section), you should be notified before upgrading to Ubuntu 18.04 within a few days of Ubuntu 18.04 release. Since Ubuntu servers encounter heavy load on the release day, not everyone gets the upgrade the same day.

For Ubuntu 16.04 users, it may take several weeks before they are officially informed of the availability of Ubuntu 18.04. Usually this will happen after the first point release Ubuntu 18.04.1. This point release restores the newly discovered bugs in 18.04.

If I upgrade to Ubuntu 18.04 can I downgrade to 17.10 or 16.04?

No, that is not possible. While upgrading to the newer version is easy, there is no option to downgrade. If you want to go back to Ubuntu 16.04, you will need to do a fresh install.

Can I use Ubuntu 18.04 on 32-bit systems?

Yes and No.

If you are already using the 32-bit version of Ubuntu 16.04 or 17.10, you may still get to upgrade to Ubuntu 18.04. However, you won’t find Ubuntu 18.04 bit ISO in 32-bit format anymore. In other words, you don’t have a fresh install of the 32-bit version of Ubuntu 18.04 gnome.

The good news here is that other official flavors like Ubuntu mate, Lubuntu etc still have the 32-bit ISO of their new versions.

In any case, if you have a 32-bit system, chances are your system is weak on hardware. You’ll be better off using lightweight Ubuntu mate or Lubuntu on such a system.

Where can I download Ubuntu 18.04?

Once 18.04 is released, you get the ISO image of Ubuntu 18.04 from its website. You have both direct download and torrent options. Other official flavors will be available on their official websites.

Do I need a fresh install of Ubuntu 18.04 or upgrade to it from 16.04/17.10?

If you have a choice, make a backup of your data and do a fresh install of Ubuntu 18.04.

Upgrading to 18.04 from an existing version is a convenient option. However, in my opinion, it still keeps some traces/packets of the older version. A fresh installation is always cleaner.

For a good install, should I install Ubuntu 16.04 or Ubuntu 18.04?

If you are going to install Ubuntu on a system, go for Ubuntu 18.04 instead of 16.04.

Both are long term support release and will be supported for a long time. Ubuntu 16.04 gets maintenance and security updates up to 2021 and 18.04 to 2023.

However, I would suggest that you use Ubuntu 18.04. Every LTS release gets hardware updates for a limited time (two and a half years I think). After that, it only gets maintenance updates. If you have newer hardware, you will get better support in 18.04.

Also, many application developers will start focusing on Ubuntu 18.04 soon. Newly created GDP can only support 18.04 in a few months. The use of 18.04 has its advantages over 16.04.

Will it be easier to install printer scanner drivers instead of using the CLI?

I’m no expert when it comes to printers, so my opinion is based on my limited knowledge in this area. Most of the new Printers support IPP protocol and so they should be well supported in Ubuntu 18.04. I can’t say the same thing about older printers.
Does Ubuntu 18.04 have better support for Realtek and other WiFi adapters?

No specific information on this part.

What are the system requirements for Ubuntu 18.04?

For the standard GNOME version, you will need 4 GB of RAM for a comfortable use. A processor released in the last 8 years will also work. Something older than that should use a lightweight Linux distribution, such as Lubuntu.
