--> Finished Dependency Resolution
Error: Multilib version problems found. This often means that the root
cause is something else and multilib version checking is just
pointing out that there is a problem. Eg.:

1. You have an upgrade for libxml2 which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of libxml2 of the
different architecture. If you exclude the bad architecture
yum will tell you what the root cause is (which package
requires what). You can try redoing the upgrade with
--exclude libxml2.otherarch ... this should give you an error
message showing the root cause of the problem.

2. You have multiple architectures of libxml2 installed, but
yum can only see an upgrade for one of those arcitectures.
If you don't want/need both architectures anymore then you
can remove the one with the missing update and everything
will work.

3. You have duplicate versions of libxml2 installed already.
You can use "yum check" to get yum show these errors.

...you can also use --setopt=protected_multilib=false to remove
this checking, however this is almost never the correct thing to
do as something else is very likely to go wrong (often causing
much more problems).

Hi Mike,

From your description, I understand that currently, you are running in version 7.7.2.x. An upgrade to 7.8.2.x version it will be a phased upgrade.

This is a phased upgraded from MLOS2 to MLOS 3. Till 7.8.1.6, it is MLOS2 and then it is MLOS3.  As this is phased upgrade first it will upgrade to version 7.8.1.6. For an upgrade from MLOS2-MWG (older than 7.8.2.0) to MLOS3-MWG (>= 7.8.2.0) in one go, the following procedure should work:-

To upgrade MWG 7.8.2.x in one step:

mwg-switch-repo main or mwg-switch-repo --sticky <mwg version>

yum clean all              # optional.

yum upgrade yum            # this will install yum + mlos3-upgrade package.

yum upgrade mlos3-upgrade  # if the mlos3-upgrade package not installed this will upgrade the mlos3-upgrade package or if old version of mlos3-upgrade is installed.

yum upgrade                # this command should start the mlos3-upgrade process which will automatically upgrade to 7.8.1.6 -> 7.8.2.0 -> 7.8.2.x 

reboot                     # The mlos3-upgrade process will do a system reboot which automatically if the upgrade will complete successfully.

NOTE:-  Above steps will work assuming you have direct internet access provided for web gateway.

Before performing this upgrade, please take a backup of the config.

We suggest doing upgrades via the command line and the "yum" command. This gives you more control and visibility into the process. Please make sure you have root access to the command line for this.

Finally, always reboot the appliance after upgrading.

Please refer below link for more information on MWG upgrade:-

https://kc.mcafee.com/corporate/index?page=content&id=KB89192&elqTrackId=D824897F4BE515C4A655E2D408F...

Please log the Putty Session when you perform the upgrade.

If the above steps don't help, do raise a Support SR and share the Putty Session Logs and the Feedback File so that we can understand the cause of the problem.

Thanks,

Shibani
