Trying to install a rpm and I get this message
[root@localhost 1-linux]# rpm --install glibc-~1.rpm
error: failed dependencies:
glibc < 2.2.5 conflicts with glibc-common-2.2.5-34

so I thought by removing the older one would work but it wont let me. what should I do

ttt

Typically when upgrading glibc via rpm the installation instructions are going to be a little different than installing other rpms. Usually, they'll recommend doing a force (-F). There are a lot of caveats. You might read your OS vendor's docs for applying that update.
