• The workflow log does not exist in /data01/avamar/repo/temp/<packagename>/tmp

• Avinstaller.log reported errors such as the following during flush (this may have been reported for some months):

INFO: Flush exit stderr: sudo: cannot get working directory
shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
job-working-directory: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory

From Avamar 7.5.1.x, the avinstaller process runs as avi as opposed to root (prior to v7.5.1.x).

1. Access the AvInstaller directly using one of the following:

https://<avamar-server-name>:8543/avi

-- Or --

https://<avamar-server-name>/avi

2. Restart the avinstaller.

3. Retry the installation.
