What is a 'damaged header'?

edkilp · #1 27th July 2004, 05:09 PM

I just did a clean install of FC2. I tweaked my yum.conf (as usual), and did a "yum update" (as usual). This time. I'm getting this:

kernel-0-2.6.6-1.435.2.3. 100% |=========================| 140 kB 05:01
Damaged Header /var/cache/yum/updates-released/headers/kernel-0-2.6.6-1.435.2.3.i686.hdr
kernel-0-2.6.6-1.435.2.3. 100% |=========================| 52 kB 05:01
Damaged Header /var/cache/yum/updates-released/headers/kernel-0-2.6.6-1.435.2.3.i686.hdr

what's up with this? Last night DAG was broke, and wouldn't let me install anything. I've seen this damaged header thing before. Do I need to do anything to fix this? Thanks

Delete the file and let it download one more time.

why doesn't yum automaticaly remove and update broken headers when it finds one? just thought I'd ask.

I still don't know what it is. What's damaged? What causes the damage? What are the effects of a damaged header to my system? Why is my big toe smaller than my middle toe?

To understand what a damaged header is, one have to understand what a header is.

A header is a tiny file with information about one package available in a repository. Each available package has one header file. Yum will use the headers to check for dependencies, get file sizes and such.

If Yum starts to download a header, but is aborted, you're left with a partial or damaged header. These headers are useless and must be removed or replaced by a good header. Yum should do this automatically.

To force a redownload of all the headers run

Code:

yum clean headers

what if i

Code:

yum clean headers

and i get

Code:

[root@Klamathia root]# yum clean headers
Gathering header information file(s) from server(s)
Server: Fedora Core 1 - i386 - Base
Damaged or Bad header.info from Fedora Core 1 - i386 - Base
This is probably because of a downed server or an invalid header.info on a repository.

Then try to manually remove the headers:

Code:

rm -f /var/cache/yum/base/headers/*.hdr

After doing this, you'll have to get all the headers again, which will take some time.

ok i ran that last bit of code and i still get:

Code:

[root@Klamathia root]# rm -f /var/cache/yum/base/headers/*.hdr
[root@Klamathia root]# yum clean headers
Gathering header information file(s) from server(s)
Server: Fedora Core 1 - i386 - Base
Damaged or Bad header.info from Fedora Core 1 - i386 - Base
This is probably because of a downed server or an invalid header.info on a repository.

p.s. i ran

Code:

yum list

and now it apperars to be working
thank you all for your help
