1. Run 'slackpkg new-config' to merge /etc/sbopkg/sbopkg.conf.new with /etc/sbopkg/sbopkg.conf.
2. ... or modify /etc/sbopkg/sbopkg.conf
Code:
-REPO_BRANCH=${REPO_BRANCH:-14.1}
+REPO_BRANCH=${REPO_BRANCH:-14.2}
3. ... or run sbopkg and select Utilities -> Repository -> 14.2 -> Yes to save /root/.sbopkg.conf.
This setting has precedence over /etc/sbopkg/sbopkg.conf. So if you use (1) or (2) than remove /root/.sbopkg.conf with old settings.
