Howdy,
When are you receiving those errors/warnings? Is that the output you receive from the backup?
-Eric
Yes that is the emailed output.
Okay, one last question... is that the normal output of the script, or are you saying you added "use strict" to the script, and after adding that, you're seeing those errors?
-Eric
No I added nothing to the perl script.
When coding in perl if you use: use strict; at the top of your file when you run it it will inform you of errors allowing you to fix them before distributing the file.
The "Use of uninitialized value" errors show that there is a probably problem with a variable.
Okay, just wanted to make sure :-)
It sounds like a bug then -- I'd suggest filing a bug report, using the Support link above.
While I'm not sure what's causing those errors in your case, Jamie can work with you to figure that out.
What he'll need to know though is all the settings for this particular backup, so that he can dig down into the problem. If you happen to have a screenshot of the settings, that might be helpful. Thanks!
-Eric
Thanks! I'll let Jamie know in the bug tracker.
Having exactly the same error/report after update for webmin, please post fix if any
I'm not sure that the version of Webmin fixing this issue has been released yet.
In the meantime, what you can do is tweak the cronjob that generates those messages so that it's quiet.
To do that, look for where "/usr/libexec/webmin/backup-config/backup.pl" is being executed in your root user's crontab, and add "2>/dev/null" to the end. The full command would look like:
/usr/libexec/webmin/backup-config/backup.pl 2>/dev/nullThat will prevent you from getting all those warnings.
