DNF Update fails: ImportError: /lib64/libdw.so.1: file too short

,

Hi @all,

I’m trying to do an update on my existing Fedora 32 system by “sudo dnf update” what happened to work fine until last week.

Now I’m getting an error saying “ImportError: /lib64/libdw.so.1: file too short”

What can I do to make dnf work again?

Yours

Chris

Very strange.
What is the result of this command?
rpmverify elfutils-libs

[christian@localhost ~]$ rpmverify elfutils-libs

…L… /usr/lib64/libdw.so.1
S.5… /usr/lib64/libasm-0.181.so
S.5… /usr/lib64/libdw-0.181.so

This means that something has modified these files. :thinking:
You should try to download the elfutils-libs rpm file and reinstall it with the rpm command.

Sorry, I’m somewhat lost. How do I reinstall?

I tried the following but I got even more erros.

I could only reinstall it by using the --force command.

Unfortunately dnf update fails again. :frowning:

Is my installation totally broken?

Mmm, the latest version is elfutils-libs-0.181-1.fc32.x86_64.rpm

At least, now, dnf works.

Try with sudo dnf distrosync
What happens?

Out of curiosity, what is the result of this command?

file /lib64/libbluetooth.so.3.19.3

Finally I installed v181 by using the --force command again.

Now I got these errors:

Mmm.
Well, since you are running 5.8.6-201 kernel, you can safely remove all the packages related to kernel 5.8.4-200
Try to run this command, but before confirming, please paste here the result.
