An issue appeared during a previous rollup installation attempt, for example: NVE: AVI service failing to start post OS Update 2025 R2-v3
There is an issue with the post_errata_installation XML file associated with the previous rollup.

1. Open an SSH session to the NVE and login as admin.
2. Switch to root: sudo su -
3. Check if NVE latest installed Rollup: avosrollup -V

nve:~ # avosrollup -V
Avamar Platform OS Security Rollup:
OS[SLES12.5] Version[2025-R2-v3] Installation Time[2025-10-17-13-01-37]

This indicates that the rollup is already installed on the system. However, it has not completed the process yet.

4. Check if the rollup's post_errata_installation XML file exists: grep package-survey /usr/local/avamar/var/package-survey-*-post_errata_installation*.xml

nve:~ # grep package-survey /usr/local/avamar/var/package-survey-*-post_errata_installation*.xml
:::::
/usr/local/avamar/var/package-survey-SLES12.5-post_errata_installation-2025-10-17-13-01-37.xml:<package-survey version="2025-R2-v3"/>
/usr/local/avamar/var/package-survey-SLES12.5-post_errata_installation-2025-10-17-13-01-37.xml:<package-survey>
/usr/local/avamar/var/package-survey-SLES12.5-post_errata_installation-2025-10-17-13-01-37.xml:</package-survey>

5. Remove the xml files associated with the package it alerted as "already installed"

nve:~ # mv /usr/local/avamar/var/package-survey-SLES12.5-post_errata_installation-2025-10-17-13-01-37.xml /tmp
nve:~ # mv /usr/local/avamar/var/package-survey-SLES12.5-pre_errata_installation-2025-10-17-13-01-37.xml: /tmp

6. Restart the AVI service: avinstaller.pl --restart
7. Log in to the NetWorker Install Manager UI, continue the rollup update process by clicking "Retry Current Task."
