apt-get update error
 

When I run
sudo apt-get update

it runs and then stops with this error:

Aborted (core dumped)
Reading package lists... Done
E: Problem executing scripts APT::Update::Post-Invoke-Success 'if /usr/bin/test -w /var/cache/app-info -a -e /usr/bin/appstreamcli; then appstreamcli refresh > /dev/null; fi'
E: Sub-process returned an error code

Any ideas?

Can you try running the following command on its own (which appears to be failing) and let us know what happens:

Same results
ffffffffff600000-ffffffffff601000 r-xp 00000000 00:00 0 [vsyscall]
Aborted (core dumped)

both "appstreamcli refresh" and "apt-get refresh" fail on vsyscall

tj

this is something that gets executed after updates.
up to you to find out what it does, or which package it belings to.
maybe you can safely ignore it, or remove it from apt config.

Thanks. Ok, let's try reinstalling the relevant component of appstream. First, to determine which version of libappstream you have, can you run the following:

It was libappstream3. Purges it and problem went away.
