Hi Folks,

I used Ubuntu 20.04 on my host and it looks like I didn’t hit an issue. I just replaced the lsb-release file. The only three packages that failed, it for vision API. In essence, SDK Manager is trying to poll one minor version behind.

Is there any option in SDK Manager to adjust the version for a minor release for dependencies? For example, if you need libX5.1 and you want to change that to LibX5.2.

Thank you

Hi spyroot,

No, that’s not supported.

Is there a log which bugs were fixed for this release, e.g. in the Multimedia API (Buffer API, Encoder, Decoder)?
