Description Terry Froy 2017-09-23 19:43:57 UTC 
Description of problem:

Reinstalled my machine with Fedora 26 and manually installed clatd as my home LAN is IPv6-only.

Connectivity remained IPv6-only due to failure of clatd to start.

Version-Release number of selected component (if applicable):

clatd-1.4-3.fc26

How reproducible:

Always

Steps to Reproduce:
1. Fresh install of Fedora 26 Compiz-MATE spin (probably will work on vanilla Fedora 26 too)
2. yum install clatd
3. Connect Ethernet interface to IPv6-only LAN which advertises DNS servers that are enabled for DNS64.

Actual results:

Additional info:

I ran 'yum install perl-Net-IP' after getting the logs provided above in 'Actual results' which were used to provide the 'Expected results' logs.

Once this was dependency was fulfilled and the interface state was cycled, clatd started and was fully operational.

The changelog in the RPM states:

* Tue Jun 28 2016 Ingvar Hagelund <ingvar> 1.4-2
- Fixes for bz#1302876, including
- Now BuildRequires pod2man
- Requires perl(Net::IP) is autogenerated, so not needed explicit
- clatd.conf is marked as config file
- Packaged 1.4 release tarball, and added changes from upstream as patches

I suspect that at some point in time, the autogenerated dependency on perl-Net-IP is no longer present and either this should be investigated as to why it is no longer present in the package *or* it should be re-added as a manual dependency in the package specfile.

Comment 2 Ingvar Hagelund 2017-09-26 09:57:25 UTC 
Hi, Terry

Thanks for the report. By some reason, the automatic requirement of Net::IP fails when the package is built in mock, which is what the builders do.

I'll readd the requirement of Net::IP and update the package.

[root@cybernoid tez]# rpm -e perl-Net-IP
[root@cybernoid tez]# yum --enablerepo=updates-testing update clatd
