Hello, I've tried to find a solution in the mailing list archive, but I did not find the trick that could help me. I've just upgraded from FedoraCore 2 to FC3, and I used to update my home computer (I don't the adsl at home), using my laptop wireless (at work the adsl is available). Using FC2, I run "yum-arch -l ." to create the local repository on my laptop, and a yum update from my home computer with the following entries in my /etc/yum.conf, worked like a charm. --------------------- [main] cachedir=/var/cache/yum debuglevel=3 logfile=/var/log/yum.log pkgpolicy=newest distroverpkg=redhat-release tolerant=1 exactarch=1 retries=20 [laptop] name=LocalStuff baseurl=file:///mnt/celtes5/usr/local/myrepo ---------------------------------- Now, using FC3, I saw yum-arch, was useless, and I have to use createrepo. I've tried the following two ways : createrepo /usr/local/myrepo and createrepo -u file:///usr/local/myrepo /usr/local/myrepo Both seems to work. But on my home computer, when I run a yum update, I have the following error message : [root@celtes2 fm]# yum update Yum Version: 2.1.11 COMMAND: yum update Installroot: / Setting up Update Process Setting up Repo: laptop Baseurl(s) for repo: ['file:///mnt/celtes5/usr/local/myrepo'] repomd.xml 100% |=========================| 1.1 kB 00:00 Setting up Repo: base Cannot find a valid baseurl for repo: base How can I do to make to work as before ? Thank you. Francois
