Drop Ubuntu 20.04 support for apt dependencies

[traversaro]

I know that we did not fully even solved #481. Anyhow the problems related to Ubuntu 20.04 apt dependencies are increasting, so I wanted to start opening this issue to start collecting things that block us from updating to 20.04:

• JetPack SDK stuck to Ubuntu 20.04
• iCubOS not running on Ubuntu 20.04
• AMI machine(s) not updated to Ubuntu 22.04

@Nicogene do you know the situation of icub-tech's machines and Docker images?
@xEnVrE do you know about the situation of HSP's machine or other constraints (like in #481 we had CUDA-related problems).

Hi @traversaro,

at the moment all the machines (personal and those of iCubGenova11) are mostly using Ubuntu 20.04 - but I counted at least 3 machines already using Ubuntu 22.04.

I would say we would need to update at least those of iCubGenova11 when the support is removed. I cannot comment on the machines of the R1 setup - not sure they are using the superbuild.

As regards applications w/ CUDA they mostly run on docker where we have, I think, a mix of situations (ranging from Ubuntu 18.04 to Ubuntu 22.04) and not all of them require the software provided by the superbuild.

@valegagge can confirm it but I think that the docker images are focal-based:

Hi @Nicogene ,

@valegagge can confirm it but I think that the docker images are focal-based:

yes!I confirm.
When we are ready to move to the 22 we can start to update the docker images and our laptops.
