[Solved] Failed to install NDK/Caffe prerequisites

Hi @paulbuxton;

 we installed ubuntu 20.04 on a newly formatted hardware. The warnings we had for 22.04 continued to appear as in the attachment. Any ideas how to fix this problem?

thanks

@luispimo This fixed the problems both for ubuntu 20.04 and 22.04. Thank you.

"Hi @hight 

Apparently it seems an issue related to apt/sources.list.

It is possible that the source.list is corrupted.

You can try the following:

1. Remove the file: sudo rm /etc/apt/sources.list
2. Create an empty one: sudo touch /etc/apt/sources.list
3. Restore the default settings using "Software & Updates" tool (see attached image)

Regards

Luis"

hi

Towards the end of ncsdk installation on Ubuntu 20.04  I am getting the verification results with 3 failures and 3 SUCCESS as in Fig 1.

When tried again I could catch an error message as in Fig 2. Finally it terminates with '1' error, as in Fig 3. I have been trying to identify and fix the source of the problem, but no hope so far. Any suggestions will be most appreciated.

Thank you.

Hi, looking into this. There has been an issue recently where some packages have changed dependencies, I am not usre if this is the cause.

Hi,

I have going through the setup I see that there is a problem with protobuf which will get installed during the process. Re-going through the setup process on Ubuntu 20 I was able to get a clean install using the following steps before running the ncsdk installer

apt-get update
apt install libjpeg-dev python3 python3-pip git curl cmake 
pip install protobuf==3.20.0
apt install virtualenv caffe-cpu

@paulbuxton 

I will try this* on a clean installation of 20.04. In the meantime we installed ubuntu 18.04, on a 12 core machine with an over kill RAM size. The installation was flawless and very fast. 

I will retry later with 20.04 on the smaller scale machine with your suggestions, just to pin point the solution to the problem. 

Many thanks.

apt-get update apt install libjpeg-dev python3 python3-pip git curl

cmake pip install protobuf==3.20.0 apt install virtualenv caffe-cpu

I have tested Paul's solution and it works ok for Ubuntu 20.04.4
