Ubuntu Studio shares some of the desktop features with Kubuntu. Please see [Kubuntu release notes](https://wiki.ubuntu.com/FocalFossa/ReleaseNotes/Kubuntu)
 for additional information.

# Getting Ubuntu Studio 21.04

## Download a Disk Image

- [Bootable images for standard PCs/laptops](http://cdimage.ubuntu.com/ubuntustudio/releases/21.04/release)

Instructions for burning the image to a DVD or USB flash drive can be found on the [Burning ISO Howto](https://help.ubuntu.com/community/BurningIsoHowto)
.

## Check MD5SUM for the downloaded ISO

It is recommended to [check your image file](https://wiki.ubuntu.com/HowToMD5SUM)
 so your installation goes smoothly. Compare your MD5 checksum with the correct ones found [alongside the images](http://cdimage.ubuntu.com/ubuntustudio/releases/21.04/release/MD5SUMS)
.

## Upgrading to Ubuntu Studio 21.04

**Due to the change in desktop environment, direct upgrades to Ubuntu Studio 21.04 from versions *prior*to 20.10 are unsupported.**

Direct upgrades from Ubuntu Studio 20.10 will be supported.

To upgrade, ensure the package **ubuntu-release-upgrader-qt** is installed press *alt-space* to invoke Krunner, and type the following:

```
pkexec do-release-upgrade -m desktop -f DistUpgradeViewKDE
```

Alternatively, you can do this from the Konsole terminal:

```
sudo do-release-upgrade -m desktop
```

# Known Problems

- Ubuntu Studio uses the same KDE Plasma desktop environment as the official Kubuntu release, and thus, may be affected by some of the same issues. This is also true of the core packages of the mainline Ubuntu release. You can see their release notes [here](https://wiki.ubuntu.com/HirsuteHippo/ReleaseNotes/Kubuntu) (Kubuntu) and [here](https://wiki.ubuntu.com/HirsuteHippo/ReleaseNotes) (Ubuntu)

# Support

Ubuntu Studio 21.04 (Hirsute Hippo) will be supported for 9 months until January 2022. **Direct upgrades to Ubuntu Studio 21.04 from versions prior to 20.10 are not supported.**
