I feel you are doing something wrong.

Where did you run apt-get update? On xavier? or somewhere else?

Where did you run sdkmanager? On xavier? or somewhere else?

3

SDK manager I am running on the Ubuntu 20.0 host machine and also I tried by taking remote access through terminal. The everywhere common error is ‘https://repo.download.nvidia.com/jetson/common r35.4 Release’ no longer has a Release file.

4

Does your Xavier just get flashed or it has been flashed for a while and you just run apt-get recently?

5

Xavier have been flashed 1 month back and now I trying for apt-get but it is throwing error. Even if I am trying to install pip library I am getting the same error.

6

Try to remove the 35.4 thing from apt source list and run apt-get update again.

7

May I know the path from where I can access 35.4 file

8

/etc/apt

9

After removing 35.4 file still getting the error.

Hi Wayne, Could you please help me to solve this error.

Hi,

We have no issue with same repo on our side. It could be your network environment issue that some ubuntu repo cannot be accessed in your area.
