Solaris Package Update failing due to incorrect pkg path

I am trying to update a Solaris 11.4 box from SRU36 to SRU37 but I am receiving errors due to conflicting attributes.

The package path for SRU36 seems to be missing "/so" from the path but I am unsure as to where this information is pulled from in order to try to alter it, if possible.

    The requested change to the system attempts to install multiple actions
    for link 'usr/lib/libcares.so.2' with conflicting attributes:
    1 package delivers 'link path=usr/lib/libcares.so.2 target=libcares.so.2.4.2':
    **pkg:/laris**/library/libcares@1.17.1,11.4-11.4.36.0.1.101.0:20210716T013410Z
    1 package delivers 'link path=usr/lib/libcares.so.2 target=libcares.so.2.4.3':
    **pkg://solaris**/library/libcares@1.17.2,11.4-11.4.37.0.1.101.1:20210825T145948Z

I have tried to upgrade directly to SRU38 and SRU39 we same result plus a few other packages throwing the same error.

Any help or advice with this would be greatly appreciated. Many Thanks in advance

Solution

What needs to be done:

o ensure that a UTF-8 is used throughout

o remove the cache in the zones (- remove the pkg cache in the zones (cd /var/pkg/cache; rm -rf *))
