Environment

Aria Operations for Networks 6.13
Aria Operations for Networks 6.14

Cause

During installation, the unpacking of the miniconda3 tarball fails, resulting in incomplete setup with missing files and/or incorrect permissions.

Resolution

To resolve the issue, delete the miniconda3 directory and unpack the files again from the miniconda3 tarball found on the platform node.

Login to the Platform node 1 as the "support" user
Switch to “ubuntu” user
```
ub
```
Confirm the miniconda3 distribution file exists. If it does not: stop and request further assistance.
```
cd /home/ubuntu/build-target/batch-analytics/

ls -lrth | sort
```
Review results for miniconda3.tar.gz present in this directory.
Delete the existing miniconda directory
```
sudo rm -rf /opt/miniconda3
```

Untar the miniconda3 tarball

sudo tar -zxf ~/build-target/batch-analytics/miniconda3.tar.gz -C /opt

Check for contents and permissions of newly created miniconda3 directory, all contents of miniconda3 directory must have “ubuntu:ubuntu” ownership and the key contents are bin, etc, lib.
```
cd /opt/miniconda3/

ls -l
```
The permissions and ownership should match the list below as seen in screenshot:

-rw-r----- 60.1
drwxr-x--- bin
drwxr-x--- compiler_compat
drwxr----- condabin
drwxr-x--- conda-meta
drwxr----- envs
drwxr-x--- etc
drwxr-x--- include
drwxr----- lib
drwxr-x--- libexec
-rw-r--r-- LICENSE.txt
drwxr-x--- licensing
drwxr----- man
drwxr----- pkgs
drwxr-x--- sbin
drwxr-x--- share
drwxr----- shell
drwxr-x--- ssl
drwxr----- x86_64-conda_cos6-linux-gnu
drwxr-x--- x86_64-conda-linux-gnu

If the ownership and/or permissions do not match, please use standard Linux commands to update the ownership and/or permissions so that they do match before continuing. Or reach out to Broadcom Support for additional assistance.

Configure conda auto_activate_base as false

/opt/miniconda3/bin/conda config --set auto_activate_base false

Restart the batch analytics service

sudo systemctl restart batch-analytics.service

Navigate back to GUI and re-run query discovered applications, it should process it and error shouldn't be seen, Application Discovery Feature should work as expected.
