Description of problem: I had a Fedora 13 installation on my desktop, which I just ran a yum upgrade on. Now rpm and yum are both pretty broken due to an undefined symbol 'pgpValString' in librpm: [root@localhost ~]# yum There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: /usr/lib64/librpm.so.1: undefined symbol: pgpValString Please install a package which provides this module, or verify that the module is installed correctly. It's possible that the above module doesn't match the current version of Python, which is: 2.6.4 (r264:75706, Jun 4 2010, 18:20:31) [GCC 4.4.4 20100503 (Red Hat 4.4.4-2)] If you cannot solve this problem yourself, please go to the yum faq at: http://yum.baseurl.org/wiki/Faq [root@localhost ~]# rpm -qi rpm rpm: symbol lookup error: /usr/lib64/librpm.so.1: undefined symbol: pgpValString Version-Release number of selected component (if applicable): [root@localhost ~]# rpm -q rpm rpm-libs yum Freeing read locks for locker 0x31fd: 3659/140596657260448 Freeing read locks for locker 0x31fe: 3659/140596657260448 Freeing read locks for locker 0x31ff: 3659/140596657260448 rpm-4.8.1-2.fc13.x86_64 rpm-libs-4.8.1-2.fc13.x86_64 rpm-libs-4.8.1-2.fc13.i686 yum-3.2.27-4.fc13.noarch How reproducible: I'm not sure how to reproduce this. My guess is there's something not right in the Python libraries, but I'm not sure what. I upgraded my system from F-12 shortly after F-13 was released and haven't upgraded it since, until today.
Ah... It seems a copy of librpmio got installed to /usr/local/lib back in May when I was fixing a bug debugedit. I don't recall installing it myself, but I may have done.
