I normally use aria2c (but not as root). If I remember, I use the “-V” option to aria2c, to verify the download.
I typically see a few errors such as you are seeing, but I allow it to continue. And it usually completes correctly. Normally aria2c samples several possible sources. So if it reports errors from one source it is supposed to switch over to another.
I’m not sure what happened in your case, but it looks as if you use ^C to abort, instead of allowing it to continue.
For 12.3, I found the iso at a mirror about 1 day early, so I used “wget” instead of “aria2c”. And that gave me a good download. I verified the download with pgp (okay, with gpg). The md5sum that I compute agrees with the md5sum at the site.
I had a similar problem for the 64-bit iso. i tried by http, Bittorrent, and MetaLinks (downThemall). For the http and torrent downloads I tried the md5 checksum and it failed. For the Metalinks case I got an error after the download that the checksum had failed, and did I want to recover. I tried recovery, and the same failed checksum error came up. This was on 3/14. On 3/15 I tried again using http and the Metalinks methods. The metalinks failed again, both originally and recovery, but the http succeeded. I burned the DVD successfully, but have other installation issues, discussed in another thread.
Yes, when I saw the error pop up I didn’t think it prudent to wait five hours to confirm it so I hit CTL-c. Next time I’ll trust aria2c to handle it. Thanks for the instructive response.
I have had similar problems downloading the 12.3 x_64 DVD. I am getting results that make no sense to me.
I have downloaded by direct link and also by choosing a nearby server. All downloads failed the md5 checksum comparison.
I ran aria2c and it claimed success, but that file also fails the check.
What is strange is that two different md5 programs come up with different md5 sums for the same file. KCheckHash shows: 5e007223641163aab6bdfb6c9a8e2944.
md5sum ran from a terminal shows: fad6c8aa8599716737b00d76325c04ad
The correct md5 sum should be: 02f33a86ff8e89c415f59da2618f4930 The checksums are for the file downloaded by aria.
I had done a “net” upgrade from 12.2 and had a couple of problems after the upgrade. It may be possible that the upgrade broke something, but I have no way to be sure.
For now, I’ll check the md5 from W[size=2][size=2]indows to see what I come up wi[size=2]th. [/size][/size]Each download takes 9 or 10 hours, so I am hoping that I can find a solution soon.

Well, WinMD5Sum came up with 12bffedf00a1f19a7b4f556f7523bc14 for a checksum. I guess the last thing to try would be to burn it and allow it to “self test” after boot.

Aria2c can check the signature itself. Rerun it with the -V parameter,
it should recheck what it has downloaded.
If you are checking from Windows, be aware that there are some checksum
programs that fail to check correctly, they are buggy and give incorrect
result.
All this assumes you are not downloading to a FAT partition: it can not
hold the DVD image, it is too big.

Actually, I had copied your post of the command directly from this thread. When I noticed that it had finished, I was running my computer by remote from my cell phone and did not copy the output directly. I’ll run it again.
But I didn’t use “-V” parameter. And it has created many files with names: openSUSE-13.1-DVD-i586.iso.meta4.x, where x=1, 2, 3,…each time I start the download with the above command (in the same directory), though it starts from where it left…
It is not needed unless the download has already finished and you want to check it a second time.

Just delete them. Have a look inside with a text editor, and you will see how it works.

Right.
> Further how to check the md5sum?
aria2c does that automatically. If you let it finish, it has already checked.
If you want to check it yourself the instructions are in the download help page on the wiki.

To look the file " openSUSE-13.1-DVD-i586.iso.meta4.x" with a text editor?
And other thing I noted is that the speed doesn’t go beyond 55 KiB with aria2c (don’t know why) because comparatively Deluge downloads at around 100-110 KiB! But I believe, it does some extra tasks also, so it is compensated…!

If you are curious, yes.
For example, it contains the list of mirrors for your region.

No, it should be faster, unless you tell it to go slow, or if your cpu is too slow. Maybe it can not
find mirrors on your region. You can tell it to try more mirrors.

Just open the meta4 file with a text editor and you will see the list of mirrors inside.
Don’t try to specify mirrors to aria2c on the command line, that doesn’t work. You have to specify a
link to the meta4 file.

I would open a Bugzilla on the issue. This is not normal.
