Impossible to use latest release 4.4 on Ubuntu 22.04

Processing Beginners
1

Hello all,

I was using processing 4.3 on my Ubutun 22.4. This is a standalone installing fron a tarball.

I tried to install with SnapD, the latest release 4.4 and as for now I’m not able to use the tool for the same code.

I got a bunch of errors that may explain the behavior but I don’t know what is it

Right now I can’t access to tty ports.
Is it a problem of installation or right/write access that I dont’ have ?

Thanks in advance

Hi @PyM72,

I’m wondering which version you’re running. In our 4.4.6 release (See Notes), we enabled classic confinement, which should help with some of these issues around access in the snap packages.

Let us know the version. If you’re on 4.4.6 and this is still a problem we can investigate further!
