** NethServer 7.8.2003:**
Web Filter:
I cant install web filter. I receive this:

“status”: “failed”,
“message”: “[YumTestTransactionError] Test Transaction Errors: file /var/log/ufdbguard conflicts between attempted installs of nethserver-squidguard-1.9.2-1.ns7.noarch and ufdbGuard-1.34.5-2.el7.x86_64\n”,

Confirmed. Thanks, you found a bug. Update of ufdbguard is not working too.
Transaction check error: file /var/log/ufdbguard from install of ufdbGuard-1.34.5-2.el7.x86_64 conflicts with file from package nethserver-squidguard-1.9.2-1.ns7.noarch
I think ufdbguard uses it’s own logfile now and it conflicts with the dir /var/log/ufdbguard but my dev machine has some problems, I need to fix that first but I don’t have time now.
Indeed this is a bug: the package has been added to EPEL, it wasn’t present before.
We use packages from: https://www.urlfilterdb.com/downloads/packages.html
I do not know if we can switch to EPEL package, we should make some tests.
In the meanwhile, if you want to workaround the problem, you could try this:
yum install https://www.urlfilterdb.com/files/downloads/ufdbGuard-1.34.5-CentOS7.x86_64.rpm nethserver-squidguard
I had the time to test it, but sadly the workaround doesn’t work because EPEL package takes precedence.
So we need further investigation.

OK, so we have a bug…it happens 
I tried the workaround, to no avail.
What is the process now and how do we fix our servers? Is it just a case of wait till a new upgrade is made and try again, or will there be an announcement? Sorry for my lack of experience, never had to deal with a bug like this before…all info gratefully recieved!

Muchas gracias smile:
Any workaround?
Just exclude ufdbguard from the updates
Thanks, could you explainme how do it please? 
I just hit the same bug on a test-vm.
with yum update --exclude=ufdbguard it works.
Perfect! i’t works!
Finally I applied both solutions.
First,
yum update --exclude=ufdbguard
Then I applied the command:
yum install https://www.urlfilterdb.com/files/downloads/ufdbGuard-1.34.5-CentOS7.x86_64.rpm nethserver-squidguard
and now I can install the Web Filter package.
Thanks a lot…
hello all !!

[root@NethServer ~]#
file ufdbguardd.log is empty 
EPEL has a new ufdbGuard package ready to be tested.
I did test it, but I’d like some more independent tests.
The following command installs both the NethServer package and the EPEL package (on a clean machine):
yum --enablerepo=epel-testing,nethserver-testing install nethserver-squidguard
Substitute install with update to test a machine where the URL filter is already installed.
Pay attention to ufdbGuard version: it should be 1.34.6-2.el7 (some EPEL mirrors are still serving 1.34.6-1.el7).
nethserver-squidguard version is 1.9.2-1.7.g186a20a.ns7.
Thank you.
Tested on a clean test-vm. Works perfectly.
Tested on an older test-vm with already installed packages. Works also perfectly.
Thank you for your great work Fillipo!! 
Seems to have done the charm.
Thanks.
For me doesn’t work, after update with:
yum --enablerepo=epel-testing,nethserver-testing update nethserver-squidguard
in the services appear stopped ufdb process, and when I try to restart show these error:
