Greetings. We've got a number of Fedora 9 systems at work, and most of them seem now to be stable regarding yum updates. But on one of the systems we're getting an error trying to do a "yum update": [root@mysys ~]# yum -y update There was a problem importing one of the Python modules required to run yum. The error leading to this problem was: /lib/libnss3.so: undefined symbol: et_sgn_DigestInfoTemplate, version NSS_3.2 Please install a package which provides this module, or verify that the module is installed correctly. . . . We did find that four yum-related packages were out of date on the system in question. We downloaded them "by hand" from one of the mirrors and force-installed them: yum-3.2.19-3.fc9.noarch.rpm yum-packagekit-0.2.5-1.fc9.i386.rpm yum-fastestmirror-1.1.16-1.fc9.noarch.rpm yum-utils-1.1.16-1.fc9.noarch.rpm That didn't help. Please let me know if you have any suggestions about this. I've appended some more details about the system. Thanks. -- Mike [root@mysys ~]# cat /etc/redhat-release Fedora release 9 (Sulphur) [root@mysys ~]# yum -y update There was a problem importing one of the Python modules required to run yum.
