Here we go.. this is the maintenance release of Wireshark 2.2. The repository will automatically update to version 2.4.0.
An update of Wireshark to 2.2.8 has been added to the repository. Getting at it is a bit more involved than previously. If you want to use it, add the repository following the instructions in Wireshark 2.4 on CentOS7 (TL;DR version)
yum update to get the latest repository information.
Since version 2.4.0 uses only the Qt version of the interface, remove your wireshark-gtk package with
yum remove wireshark-gtk. Add the Qt version,
yum install wireshark-qt. Now
yum update to the latest version (which will be 2.4.0). Then downgrade using
yum downgrade wireshark-qt wireshark.
That’s it.. I’d suggest you become familiar with the 2.4 version, as there’ll be multiple downgrade steps if you want to stay on the 2.2 stream.
