Because the package list is not getting updated, I’m unable to install any package from the repository. It’s strange that it says bionic InRelease' doesn't support architecture 'aarch64'. I wasn’t even able find some reasonable info on this online, so any help to get rid of these warnings is appreciated. If anymore information is required, I’m happy to coordinate.

Thank you very much.

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

hello Jayadev,

may I know what’s the source configuration, nvidia-l4t-apt-source.list.
did you revise the repo to point to r32.6 release?
