I have FC 5 on my toshiba laptop and need to upgrade the kernel in order to download the driver for my wireless card:
I got this msg when I initially try to execute yum:
[root@localhost ]# yum upgrade kernel
Loading "installonlyn" plugin
Setting up Upgrade Process
Setting up repositories
Cannot find a valid baseurl for repo: core
Error : Cannot find a valid baseurl for repo: core
I resolve this problem by going to the repos directory and uncommenting the lines baseurl....in the fedora repo files.
now when I execute yum I get this error:
loading "installonlyn" plugin
setting up repositories
[Errono 4] IOError: <urlopen error (-2, 'Name or service not known')> Trying other mirror.
Cannot open/read repomd.xml file for repository: core
failure: repodata/repomd.xml from core: [Errono 256] No more mirrors to try.
Error: failure: repodata/repomd.xml from core: [Errono 256] No more
mirrors to try.
Does anyone has a solution for this kind of problem?
I will appreciate whatever help I can get.
