Errors at Slackware installation

Magos · 09-10-2006, 02:15 PM

So I decided to install Slackware (Latest, 10.2) on my old P3-500Mhz. I use cfdisk to create 4 partitions, one for LILO, one for Swap, one for Slackware (root) and finally one large for /home. A while after selecting the "Full" installation (all packages) I start getting some errors:

grep: /var/log/mount/slackware/a/tagfile: Input/output error

I usually get these in groups of four followed by:

Installpkg error #2
There was a fatal error... (lots of text)
/var/log/mount/slackware/a/aaa_elflibs-10.2.0-i486-3.tgz

(the mentioned file varies in each message)

First I thought it might be a corrupted ISO (read that somewhere), but after re-downloading the Slackware ISO's from sunet, verifying the md5 with fsum (successfully) and burning them to CD again I still get the same error when installing.

Any ideas what might be wrong?

You could be burning corrupt CD's even if the iso's are fine.

Try (assuming your cdrom device is /dev/hdc):

Code:

dd if=/dev/hdc | md5sum

And see if the sum matches the sum for the corresponding iso.

For example, my cdrom drive is /dev/sr0. After putting the first Slackware CD in the drive:

Code:

zmk@thinkpad:~$ dd if=/dev/sr0 | md5sum
1305976+0 records in
1305976+0 records out
774e8ea9fe094e8f793c2452187d2723  -

This matches what is listed in slackware-10.2-install-d1.iso.md5

Result:

dd: /dev/hdc: Input/output error
d41d8cd98f... (etc)

The checksum doesn't match the one in the md5 file.
So, should I try to burn it at a lower speed, or?
I've never had any problems burning at the default speed before though.

Try swapping the cd-rom reader, it just takes a minute.

I've redownloaded the ISO and checked the checksum, they seem fine.
I've re-burned the CD's multiple times, same error occurs.
I've tried with 4 different CD-roms, same error on 3 of em (4th claimed it couldn't find an OS, might be broken)

Since I have such bad luck with CDs perhaps I could install over the network, or a local disk if I could get the files there. How well does linux interact with a windows network? Is it possible at all?

Hi,

Did you try lowering the burn speed? Some cd-rom disk vendors are not always the same. I always burn at a lower speed than the default. I have enough coasters and don't like the flat cd-rom type.

You could load the iso to a local hard disk and mount to the loop device then specify for the install. Another option would be NFS install.

You should search LQ, this question pops up all the time.
