English (Translated):
Error while automatically upgrading UDP Agent (Linux) drivers for Ubuntu. Check network connectivity and proxy settings, or deploy drivers manually.
The Ubuntu kernel version is not supported. If the job failure is due to updating the Ubuntu operating system and the driver is not available within a day or two, contact Arcserve Support.
Initial Troubleshooting:
- Check Compatibility Matrix and confirm Ubuntu Version 16.04.3 is supported with UDP 6.5 U2
- Confirm if Ubuntu machine is 64 bit which is only supported by UDP 6.5 U2

Log analysis:
Linux Backup Server: /opt/arcserve/d2dserver/logs

[05180]2017-12-06 16:22:11, [download_file_by_curl]: Download file command: curl '' --insecure -L --max-time 120 --retry 3 -o /opt/Arcserve/d2dserver/tmp/driver_package/linux-drivers-v6.5u2.sig 2>&1
[05180]2017-12-06 16:30:18, [download_file_by_curl]: Failed to download file arcserveudp/6.5/agentlinux/ondemand.php?update=u2&file=linux-drivers-v6.5u2.sig, error: 28 % Total % Received % Xferd Average Speed Time Time Time Current

Upgrade.log shows it failed to download the Driver file from the URL given in Log -

Subsequent Troubleshooting:
Try to access the above link from Linux Backup Server using the following 2 ways:

Curl “” --insecure -L --max-time 120 --retry 3

Or with the Browser Lynx: Start the Lynx and enter the Link in “URL to Open” field. (Screenshot below)


The Link will not be accessible if there is no Internet connection available for Linux Backup Server due to Proxy Settings. 

Entering the Proxy settings for Linux Backup Server under this path /opt/Arcserve/d2dserver/configfiles/auto_upgrade.cfg, will make the Link accessible and will Fix the Error during Backup as well.

PS: It is important to check the Internet Connectivity to the Linux Backup Server and the above are the steps done to determine it.
