Events Log Shows Failed to Apply Patches ("FileZilla")

Objective

To troubleshoot and resolve the "archiveType unknown" error that appears in the Automox Events Log when applying software updates for FileZilla.

Problem / Symptoms

During a scheduled or manual patch deployment for FileZilla, the update fails, and the following error message is recorded in the Automox console Events Log:

Plaintext

 
archiveType unknown

Root Cause

The "archiveType unknown" error occurs when the Automox Agent is unable to properly download, extract, or parse the FileZilla installation payload. Common causes include:

  • Incomplete or Corrupted Downloads: Network security tools, SSL inspection, or strict firewall rules intercepting or modifying the payload download.

  • Directory Permission Restrictions: Local file system restrictions preventing the Automox Agent from creating or writing to its temporary working directory.

  • Security Software Interference: Endpoint Detection and Response (EDR), Next-Gen Antivirus (NGAV), or Secure Web Gateways (such as Netskope or Zscaler) blocking or quarantining the downloaded installer binary.

Resolution Steps

1. Ensure Allowlisting Rules Are Configured:

Verify that all required Automox domains, IPs, and binary download paths are allowed through your network firewall and web filter.

Refer to [Agent Firewall Allowlisting Rules](Agent Firewall Allowlisting Rules) for exact specifications.

2. Verify Local Working Directory Access:

Ensure the Automox Agent process has full read/write permissions to its working directory on the endpoint:

  • Windows: C:\ProgramData\amagent\
  • macOS: /Library/Application Support/Automox/

If local security policies restrict folder creation or script execution within these directories, update permissions accordingly.

3. Check for Security & SSL Inspection Conflicts:

Review local security software logs (e.g., Netskope, CrowdStrike, Defender for Endpoint) to check if the FileZilla payload download was flagged or intercepted.

  • Temporarily disable or configure exclusions for Automox Agent binaries and temporary folders in your security software.
  • Ensure SSL/TLS inspection bypasses Automox update domain URLs to avoid payload payload modification.

4. Review Agent Logs for Payload Details:

Inspect local agent logs for specific download or extraction failures:

  • Windows: C:\ProgramData\amagent\amagent.log
  • macOS / Linux: /var/log/automox/amagent.log

Search the log files for references to FileZilla or archiveType unknown to pinpoint the exact failure point.

 

Escalation Requirements

If the issue persists after completing the resolution steps, submit a ticket to Automox Support with the following diagnostic details:

  • Affected Patch Policy Name and Device Names.

  • Screenshots of the error in the Activity/Events Log.

  • Attached local agent log files (amagent.log).
