I have BareOS installed and it has been working perfectly until this morning when I encountered the following bug in the WebUI.

Summary:

After logging into the WebUI, a blank page loads. Reloading the page results in the following error message:

  Access denied

Permission to execute the following commands is required:

list,llist,use,version,.api,.clients,.help

Read the Bareos documentation on how to configure ACL settings in your Console/Profile resources.


BareOS Version: 19.2.6 (11 February 2020) Linux-3.10.0-1062.9.1.el7.x86_64 ubuntu Ubuntu 18.04 LTS

OS Version: Ubuntu 18.04.4 LTS

What I Have Checked:

  1. using bconsole, I checked the status of all BareOS components and they are all normal. In addition last night's backups all completed sucessfully
  2. checked /var/log/apache2/error.log and found the following error:

[Wed Feb 12 08:42:45.725166 2020] [php7:error] [pid 24275] [client xx.xx.xx.xx:38130]

What Has Been Changed:

The only change to the system is that libxml was upgraded:

Upgraded:
    libxml2:amd64 2.9.4+dfsg1-6.1ubuntu1.2 => 2.9.4+dfsg1-6.1ubuntu1.3

What I have Tried:

  1. cleared cache on browser - no change
  2. restarted all bareos components and apache - no change

Any advice on how I might fix this problem would be greatly appreciated.

Hi Rick,

so you run software that has been releasen on Tuesday evening and the
only recent change you can think of is libxml2?

While you're reporting a valid problem, I'd say it is probably related
to either the upgrade to 19.2.6 (from whatever previous version you were
running) or a configuration change.

Best Regards,
Andreas

Andreas,

Thanks for the response. I did a clean install of BareOS 19.2 on a fresh server and I have not made any config changes since it was initially setup and tested - so neither of those things could have caused the problem. What is strange, is today I am able to log into the WebUI and I have not made any changes.

In case it is of any help, I am posting the messages from /var/log/apache2/error.log
