Hello,
I have a cluster of Red Hat 7.3 boxes and I'm planning to
migrate to SL 3.0.4 for now (and SL 4.0 when appropriate).
However, the documentation on 7.2->SL says I should do a 2-step
upgrade: first upgrade to RH 9 with CD-ROM, then upgrade to
SL with yum. Because I don't have CD-ROM drives on my nodes,
this is not very convenient.
I tried to use rpm to install yum-conf-30x.SL.noarch.rpm,
but it needs "--force" to ignore the conflicts with files of
old yum. Then "yum -c /etc/yum.conf.304 update yum" produces
the error messages below:
Error getting file
ftp://ftp.scientificlinux.org/linux/scientific/304/i386/errata/SL/RPMS/headers/header.info
[Errno 4] IOError: [Errno ftp error] [Errno ftp error] 500 Illegal PORT command.
Any advices on how to proceed is appreciated!
Regards,
Ping
