Description Pierre Fortin 2014-05-31 04:00:35 CEST

Description of problem: (this issue does not exist on 32 bit version)

Per https://wiki.mageia.org/en/Installation_Media#Dump_Mageia_ISO_on_a_USB_flash_drive.3F used isodumper to created bootable USB ISO from .../install/images/boot.iso; but on first write, I got "isolinux.bin missing or corrupt". Re-wrote USB with 32 bit version which worked. So re-wrote 64 bit version again, and it worked this time...  (I *hate* one-time failures).

Installing an a new Dell Inspiron 17R (5737) fails trying to read:
   /tmp/image/media/core/release/media_info/synthesis.hdlist.cz but...
        ^^^^^
Since I told the installer that my local repo is on an external drive in:
   distros/remote/mageia/distrib/4/x86_64   <==MYPATH
the file is actually in:
   /tmp/media/<MYPATH>/media/core/release/media_info/synthesis.hdlist.cz 
        ^^^^^^^^^^^^^^ 
so the install fails...

Log at F3 contains:
* comparing /tmp/image/media/core/release/media_info/MD5SUM and /mnt/var/lib/urmpi/MD5SUM.Core Release
* copying MD5SUM file of "Core Release"...
* copying [/tmp/image/media/core/release/media_info/synthesis.hdlist.cz] for medium "Core Release"...
* ...copying done
* computing md5sum or retrieved source synthesis
* urpmi error: retrieval of [/tmp/image/media/core/release/media_info/synthesis.hdlist.cz] failed (md5sum mismatch)
* urpmi error: problem reading synthesis file of medium "Core Release"
* updating media failed

Which raises these questions:
1. did copy of MD5SUM actually succeed?
2. why do I get "...copying done" on a non-existant file?

After more digging, it appears the problem is indeed an md5sum mismatch...

What's especially disconcerting is this:
# ll MD*
-rw-r--r-- 1 pfortin pfortin 576 Jan 29 17:54 MD5SUM
-rw-r--r-- 1 pfortin pfortin 576 Feb  6 17:59 MD5SUM.bad

So, apparently a bad MD5SUM was installed on Feb 6 and the correct one from Jan 29 has been restored... (?)

At least, now I can get past this point in the install, BUT... only to be still blocked by bug 10162 (64 bit install looking for "Core 32bit Release").  :(

Status: NEW => RESOLVED
Resolution: (none) => FIXED
