Description Victor Stinner 2009-10-25 22:57:56 UTC

I tried to install Fedora 12 using a Netinstall (and an USB key). I choosed the following mirror:
ftp://ftp.free.fr/mirrors/fedora.redhat.com/fedora/linux/releases/test/12-Beta/Fedora/i386/os/

Download of install.img worked without any issue (in text mode), but the first download in graphical mode failed. Using Wireshark, I saw that the installer use "REST" FTP command which is not supported by the FTP server. Trace of the FTP session (in IPV6!):

-------------

The installer proposes to retry (which doesn't change anything, the server still fail on the REST command) or to reboot the computer...

The log contains "HTTP Error 501" which is wrong: it's an _FTP_ error.

I guess that using HTTP (http://ftp.free.fr/mirrors/...) would also fail because a friend told me that Free doesn't support partial download.

Expected result: If the partial FTP/HTTP download is not supported by the server, just ignore this option (download the whole file).

I tried "wget -c" on other computer to check if Free does support partial download or not:

---------------------

wget annonces the range "Range: bytes=26518-" but Free HTTP server ignores the header. I don't know if anaconda works or not with Free HTTP mirror.

This will be fixed in the anaconda-13.x series which will be in rawhide (but not F12) by getting rid of all our old FTP code.  Instead, we are using libcurl there.
