Eddie,

Please use below steps to fix the issues on the Ubuntu host and make adjustments on Windows machine.

1. Open LXTerminal and navigate to /home/cisco/Code folder
2. Remove the code-samples folder by using following command sudo rm -rf devnet-express-code-samples
3. Clone the repository to Code folder by using git clone https://www.github.com/CiscoDevNet/devnet-express-code-samples.git command
4. After cloning, the folder structure should look like this

(mycode) cisco@ubuntu:~/Code$ pwd
/home/cisco/Code
(mycode) cisco@ubuntu:~/Code$ ll
total 20
drwxrwxr-x  5 cisco cisco 4096 May 18 18:09 ./
drwxr-xr-x 26 cisco cisco 4096 May 18 18:04 ../
drwxr-xr-x 13 cisco cisco 4096 May 18 18:09 devnet-express-code-samples/
drwxrwxr-x  7 cisco cisco 4096 Oct 14  2016 mycode/
drwxrwxr-x  6 cisco cisco 4096 Oct 17  2016 virl-utils/

5. Replace contents of the rc.local file located in /etc folder with below script

USER=cisco
BASHRC=/home/$USER/.bashrc
CODE=/home/$USER/Code/devnet-express-code-samples

cp /home/$USER/.bashrc.bak /home/$USER/.bashrc

if cd $CODE && git pull; then
    logger "git pull succeeded"
    echo 'echo -e "Code-Samples were successfully updated.\\n"' >>$BASHRC
    echo 'echo -e "Navigate to '$CODE' and start coding.\\n"' >>$BASHRC 
else
    logger "git pull failed. Make a fresh clone of a repository"
    rm -rf $CODE
    cd /home/$USER/Code &&  git clone https://www.github.com/CiscoDevNet/devnet-express-code-samples.git  
    echo 'echo -e "Code-Samples were successfully updated.\\n"' >>$BASHRC
    echo 'echo -e "Navigate to '$CODE' and start coding.\\n"' >>$BASHRC 
fi 
chown -R cisco:cisco $CODE

exit 0

6. Remove .ngrok2 folder from user's home directory using sudo rm -rf .ngrok2/ command.

7. Install flask module by using pip install flask and pip3 install flask commands

Please make following changes on the Windows machine as well.

1. Open Notepad text editor and use Ctrl+O shortcut keys to open a file. Type git-pull.bat and click Open

2. Change the contents of the file with below commands

@echo off
cd "C:\Users\Administrator.WKST1\Code\" && rmdir /s /q devnet-express-code-samples && git clone https://github.com/CiscoDevNet/devnet-express-code-samples.git >> pull_log.txt

3. Open Use me as a Terminal terminal and install flask module by using pip install flask and pip3 install flask commands.

4. Open Windows CMD and install flask using commands mentioned in step 3.

Note: The difference between steps 3 and 4 is virtual environment (venv) and global site-packages directory for python

Above steps should fix all issues we have noticed with Ubuntu and Windows machines.

Please let me know if you have any questions.

Thanks,
Armen

@yawming can you test the following 2 missions from the DNA track to see if the pod image is now working. Make sure that the 3 issues reported above are fixed.

• Test the APIC-EM Mission:
  • https://learninglabs.cisco.com/tracks/devnet-express-dna/devnet-express-np-rest-apic/05-apic-04-mission/step/1
• Test the NETCONF Mission
  • https://learninglabs.cisco.com/tracks/devnet-express-dna/dna-restconf-netconf-yang/06-dmi-05-mission/step/1

You might need to check out the pre-event setup to make sure you have access to the Ubuntu host in the dCloud pod: https://learninglabs.cisco.com/tracks/devnet-express-dna/00-pre-event-preparation/00-prep-01-prep-before-you-go/step/1

Corrected item 1 from comment above:

devnet-express/labs/06-dmi-05-mission/1.md @ line 28
module06/lab05_mission need to change to LM-4602/05-mission

I published the updated mission to stage and prod.
