Hello everyone,

I'm experiencing an issue with my daily Dr.Web Updater cron job. Each day, I receive the following error message via email:
/etc/cron.daily/drweb-update:
ERROR: Dr.Web Updater: failed to download files !
run-parts: /etc/cron.daily/drweb-update exited with return code 105

Just for your information, the databases were successfully updated manually yesterday.

/opt/drweb/update.pl
Dr.Web update details:
Update server: http://update.geo.drweb.com/plesk/1100/unix
Update has begun at Mon Jun 2 09:01:44 2025
Update has finished at Mon Jun 2 09:01:48 2025


Has anyone encountered this issue before or know how to resolve it? Any advice would be greatly appreciated.

Thank you!

Same here ... last week I have got that E-Mail and today the second one. Manual update via putty appears to work fine.

This could be related to a temporary networking issue on Dr Web's end. Please monitor the situation and do let us know if the same reoccurs tomorrow.

Hello, it's the same today...

Thank you for the update, @Goncharenko . I attempted to reproduce the issue on a test Ubuntu 24.04 environment, but when running the update task manually doesn't produce the said error. Could you please give it a go and let me know:

/etc/cron.daily/drweb-update

Thanks for the suggestion.
I ran /etc/cron.daily/drweb-update manually on my system, and no error occurred during execution.
Please see the attached screenshot for reference.

Thank you for your update. In this case, it's safe to conclude that it was due to temporary connectivity issue on Dr. Web's servers.

I do get this same error emailed on daily basis for the past week or so - I ran the cron job manually and this did not return any error, will let you know tomorrow if same message is emailed again.

Same error on daily base since 03.06.2025.

/etc/cron.daily/drweb-update:
ERROR: Dr.Web Updater: failed to download files !
run-parts: /etc/cron.daily/drweb-update exited with return code 105

 

[yohanr]

I have not seen the issue this morning after running it manually yesterday

 

[hexx_network]

Error still remains on a daily base.

 

[Sebahat.hadzhi]

@hexx_network , have you tried running the update task manually as per my previous update? If not, please give it a try.

Hi there, I am having the same problem. I ran the job manually but the notification was sent again

/etc/cron.daily/drweb-update:
ERROR: Dr.Web Updater: failed to download files !
run-parts: /etc/cron.daily/drweb-update exited with return code 109

@CharisM
I had the same message (yesterday). Perhaps the drweb-server is not stable in recent times?...

 

[Bitpalast]

It ain't. We're seeing the download warning messages again on several servers nightly.

 

[Tjerk Visser]

Same error overhere. Will follow thread for the solution.

Error codes are NOT limited to 105 codes.

The random behavior of DrWeb is also resulting in other symptoms, like 109 error codes (incompatible software) and/or failures to download files (without any output of error codes whatsoever).

I have played around a bit with the DrWeb issue and it is likely to be a bug, resulting from an unknown root cause of the problem.


In essence, the following applies or should apply :

1 - it is or should be possible to run /opt/drweb/update.pl without any issue : no error codes should be present,

2 - the /etc/cron.daily/drweb-update cronjob is resulting in an error notification by mail, on a daily basis.


This is really odd behavior, since EITHER the cronjob is buggy OR the update.pl script is behaving oddly (read: no errors similar to that of the cronjob).


Running the cronjob (as root) from Plesk > Tools & Settings > Scheduled Task Manager : new task > run now (for test purposes) does not result in errors.


Replicating this issue on various OSes (all Ubuntu) does not yield the same test results - 4 test servers, 3 failures (odd behavior), one good.


I am at a loss here ......... anybody having a clue?


Kind regards.....
