@nader-f: You're probably using an out-of-date ISO for your VM. This
issue was fixed in 16.04 a long time ago. Be sure to use the 16.04.1 ISO
and not the original 16.04 ISO in the future. The [change summary for
16.04.1][1] specifically mentions this bug as having been fixed.

I followed the instructions as #24.  Everything works now.  Thanks a lot

I got this when I tried to update today. This fixed it for me:

sudo pkill appstreamcli
sudo rm /usr/bin/appstreamcli

Then the updates worked, and a new /usr/bin/appstreamcli got installed.

[Ljiljan Veselinovic]

In order to install IBM SPSS, I had to install "libstdc++5" package. I
noticed this bug was happening after installing this package and IBM
SPSS. After removing libstdc++5 (not required to use IBM SPSS, just to
install it), I didn't experience this bug. However, this all happened in
last two days, so it could be that Ubuntu updates fixed the issue.

i can confirm this being present in xenial.

it seems to correlate with a system hard reset, maybe that system hard
reset breaks the "database" behind the program? any way to have it
autocheck for integrity every n loads or after a hard reset?

Following on for #70, one cannot install new packages for appstream if
the packages cannot be refreshed. What will be done to advise users how
to get around this problem. Finding this bug report was more luck than

The big issue here is that fresh installs all hang due to this error.
How do we get past that? Would an updated installation package be issued
by Canonical to fix this?

If you've experienced this issue today (20 May 2016) then it should now
be fixed in the archives.  Please allow a little time for the changes to
replicate around. You can then re-enable backports if you wish.

#56 & #60: Thanks Mikko & kimr - Disabling the xenial-backports is working for 
me to. 
In a 16.04 live-system backports are disabled. By a fresh install of 16.04 
backports are ENabled? 
https://help.ubuntu.com/community/UbuntuBackports
This is not an "user issue" because a lot of users never changed the backports 
ON/OFF.
It's a showstopper for 16.04 LTS.

#24 worked for me BUT with the addition of removing leftover lock files first:

sudo rm /var/lib/dpkg/lock 
sudo rm /var/cache/apt/archives/lock

Dangerous if anything apt related still running - but I think a lot of
people will CTRL-C their way out of "apt-get update" of somehow try to
kill a hung update-manager.

reload the package list when the software asks you to, as it
will hang.

For some reason Kubuntu users seems able to run 'Update Manager' without

[Bug 1579712] Re: Refresh hangs indefinitely, appstreamcli using 100% CPU

[fubuntu]

It took quite some time for me to find this solution.  When the average
user starts googling this, they are going to find all sorts of things
which do not apply, for example:

http://itsfoss.com/fix-update-errors-ubuntu-1404/
https://askubuntu.com/questions/615203/software-updates-stuck-downloading-after-15-04-upgrade

What a nightmare!  This demonstrates why the system update utility needs
to include a twitter-type client to inform the user of emerging issues
related to broken update functionality.  How else will the average user
cope with a new issue like this, when there are so many possible causes
for the same type of problem?

Yes I know, it poses the question of who should have the authority to
broadcast alerts.  Perhaps a majority vote by a jury of lead developers
or team managers who could activate the feature by signing a proposed
broadcast message with their PGP key.  Moderators of the forum or the
bug tracker would then submit proposals for broadcast messages to a
mailing list that goes to the jury.  This would eliminate the
possibility of using the broadcast system for spam.

In any case, the manual fix in the description is not sufficiently clear: many 
people who are capable of typing terminal commands will not know to replace 
'amd64' with 'i386' or whatever is appropriate.  A script which automates this 
might be a better solution.

Best quick recovery method is to launch 'top' in terminal & kill that
process ID.  It does affect Software Center, Software Updater, adding
PPA's, et cetera.

Disabling the xenial-backports is working for me to! Thanks Mikko

I really wonder how unexperienced user will deal with that problem!

I was able to resolve the problem by disabling backports, it allowed me
to do apt-get update which previously hanged up.

[Bug 1579712] Re: Refresh hangs indefinitely, appstreamcli using 100% CPU

[Olli Niemi]

I'm running Ubuntu Gnome and the user experience is horrible with this
bug when using the UI: "Software Updater" has "X" and "Stop" buttons:
"Stop" button stays gray (inactive) during the update (what is the point
of having gray Stop buttons?). It is even worse if the user (such as me)
tried to change the repository, thinking there might be something wrong
with that: "Software & Updates" -> "Ubuntu Software" -> "Download from:"
[select your mirror] -> "Choose Server" -> "Close". Then there is the
notification "The information about available software is out-of-date"
-> "Reload". And the result: forever inactive window with no possibility
to interfere.

I don't know how this is handled by the UI in the regular Ubuntu but
this case seems to be a good test case for user interaction.

[Bug 1579712] Re: Refresh hangs indefinitely, appstreamcli using 100% CPU

[Neil Mayhew]

The simplest workaround seems to be to use Ctrl-C when apt update hangs
at the end. It's already done most of the work, and this just aborts the
running of appstreamcli at the end. You can then go ahead and update any
binary packages built from the appstream source package (ie any of
appstream appstream-doc appstream-index gir1.2-appstream libappstream-
dev libappstream3 libappstreamqt-dev libappstreamqt1 that are already
installed). The use of appstreamcli in the postinst shouldn't hang
because the new versions of appstreamcli and libappstream.so.3 will
already be in place.

However, using Ctrl-C is possible only when using the command line. I'm
not sure what happens if someone is using Synaptic or Gnome Software. I
assume it would be necessary to use System Monitor to kill off
appstreamcli. I'm concerned that we could see breakage in a very large
number of Xenial installations, all of which would require manual
intervention to get them unstuck.

The fact that this is happening now, when it hasn't been reported in the
past 3 years, must be due to a subtle change in the execution
environment, maybe due to updates in other shared libraries that
appstreamcli uses. The problem is a result of reading uninitialized
memory, and in the past it must have been pure luck that the memory
always contained zeroes.

[Bug 1579712] Re: Refresh hangs indefinitely, appstreamcli using 100% CPU

[Dennis W.]

i had problems today to make "sudo apt update" it don't went away so
that i can got "sudo apt dist-upgrade"

i can terminate appstreamcli in system-monitor but that loading not all
packets

This fix has "repaired" the Problem, i quete the #24

After this working there came any Pakets it wont's to have install, is
that normally and or regulate Updates ?

"Weird, I wonder what happened that many people are experiencing this now...
Removing `/usr/bin/appstreamcli` is fine if you install the fixed package 
afterwards.

To install this manually, please do (for amd64, adjust URLs for other
architectures):

```
cd /tmp && mkdir asfix
cd asfix
wget 
https://launchpad.net/ubuntu/+archive/primary/+files/appstream_0.9.4-1ubuntu1_amd64.deb
wget 
https://launchpad.net/ubuntu/+archive/primary/+files/libappstream3_0.9.4-1ubuntu1_amd64.deb
sudo dpkg -i *.deb
```

This should solve the issue. Please report back if this is fixed, or if
you are still experiencing issues!"

Might be completely unrelated, but i noticed most mirrors have this
weird loop:
http://ubuntu.mirror.su.se/ubuntu/ubuntu/ubuntu/ubuntu/ubuntu/ubuntu/ubuntu/ubuntu/ubuntu/

i write "most", but I haven't yet found any mirror that hasn't got it.

This bug appears to also affect clean 16.04 installs as of today.
Specifically, the installer gets stuck at "Retrieving file 56 of 56".

Matthias' #24 workaround works for me. Thank you. But how the amateur,
non-technical, regular user of a !!!LTS!!! release will deal with this
bug? Fixed for me and for (lets see) 300 users... and the others?

[Bug 1579712] Re: Refresh hangs indefinitely, appstreamcli using 100% CPU

[Matthias Klumpp]

I made the summary less technical, so maybe fewer duplicates of this get 
reported when people go through the bug list. I also added instructions on how 
to fix this immediately without removing packages or moving config files around 
to the bug description, so people who find this bug don't need to read the 
whole thread to get their machines working properly again.
Cheers,
Matthias
