Hi All: As you may know, we try to keep puppet4.8 in starlingx, there is no puppet4.8 in centos8 repo. I have explored 2 approaches to enable puppet4.8 in centos8 . Option1: puppet4.8 + ruby 2.5.3(centos8 default ruby version) Option2: puppet4.8 + ruby 2.0.0 rpm (stx currently use) For Option1, after adding depends requests, and pull one patch from upstream[1], puppet4.8 can be run on centos8 now. For Option2, there is deps confliction, libgdbm.so.4()(64bit) and libreadline.so.6()(64bit) which have upgrade in centos8. Is there any concern for option1 ? And for option2 issue, is there any suggestion if option1 is not the best options ? [1] https://github.com/puppetlabs/puppet/commit/578687a00195191185f44d8cb38f4b77... Thanks. BR Austin Sun.
