After using preupgrade to faciliate an upgrade from Fedora 7 to Fedora 9, then executing several yum updates, I find myself in a loop with updates required for both thunderbird-126.96.36.199-1.fc9 AND thunderbird-188.8.131.52-1.fc7. The "Update System" panel says I have an update type, with Version ...fc9 and Updates: ...fc7 (repository fedora). yum info says .fc7 is installed and .fc9 is available; however I have upgraded three times and the .fc7 remains installed with .fc9 available. I have scanned bugzilla for a related bug report and found nothing.
One obvious thing to do is yum remove thunderbird followed by yum install thunderbird. However, I am unclear about four things. First, will this for sure install the .fc9 version? Second, will this for sure not destroy my (voluminous) email files? Third, will I get out of this strange loop? Fourth, does this warrant a bug report (I kind of don't think so)?
