F34 kernel-devel drpm checksum mismatch

[John Pilkington]

For several recent kernel updates, dnf has complained about this but has 
updated as normal.  I've just noticed that the package name looks 
strange, too.  Should it get a BZ?

FWIW, I think this is needed by the rpmfusion nVidia packages.  :-)

Thanks,

John P

This means that the delta rpm is broken for some reason. This happens 
from time to time.
So your system is loading the full rpm package in the line below.

So, there is nothing wrong with your system.

What do you think is strange about the package name?  It's a deltarpm 
file, so it shows the versions that are involved.

kernel-devel-5.15.4-101.fc34_5.15.5-100.fc34.x86_64.drpm
The package name is "kernel-devel" and this is the delta between 
versions "5.15.4-101.fc34" and "5.15.5-100.fc34".

The mismatch can be caused by one of the files getting changed on the 
system.  Then the delta won't apply correctly and the result won't match 
what is expected.

Yes, I realised after sending that a 'diff' has two sources.  I had 
thought it worth reporting as something persistent.  I don't know of any 
reason for a 'change on the system'.

Thanks.

You could try running "rpm -qV kernel-devel" and see if it flags any 
modified files.

.drpm files are delta RPMs.  Small differences between one version of a
RPM and another can be sent as delta RPMs instead of downloading and
installing the newest full RPM.

It's a toss-up whether you're better doing this, and the computer
grinding its gears to deal with it, or just downloading full RPMs and
directly installing them (I've seen the latter being quicker on high
speed broadband, and the first quicker on slow dial-up internet).

If there's been more than one RPM created between the version you'd
already installed and the update you're about to, the delta RPM may not
be useable.

Though that error message warning strikes me more as a package doesn't
match its checksum, indication corruption (during creation, download,
saving, or hacking).
