Cubbli (**C**ommon **Ub**untu **B**ased **Li**nux) is the official Linux distribution of University of Helsinki.
|
|
|
|
|
|
The current version of Cubbli Linux (Cubbli 22) is based mostly on Ubuntu 22.04. Cubbli 20 will receive updates until further notice. Cubbli 18, which is based on Ubuntu 18.04, is still getting security updates until April 2023 but will no longer receive software updates. If you wish to have the newest available software you should [upgrade your Cubbli version](https://version.helsinki.fi/it4scifi/cubbli-help/-/wikis/upgrade).
|
|
|
|
|
|
Cubbli Linux comes preconfigured to the University's environment, which means that accessing University's network services, like printers, file shares, virtual desktops, remote accessible Linux machines, High-performance computation (HPC) clusters and Virtual private networks (VPNs) should be easy.

|
|
|
|
If your computer is using any other older Linux distribution, including older Cubbli Linux distributions, you should contact cubbli-upgrade(at)helsinki.fi to get an upgrade. In most situations the update can be done remotely and shouldn't take more than 1-2 hours. [You can also do the upgrade yourself](https://version.helsinki.fi/it4scifi/cubbli-help/-/wikis/upgrade).
