packagekitd eats all the CPU

[Danielle Foré]

It just starts up and eats all the everything. Unsure what the issue is here.

[Danielle Foré (danrabbit)]

Moving to appcenter since killing appcenter-daemon temporarily addresses the issue

[Danielle Foré (danrabbit)]

According to Corentin this is related to the issue about untrusted sourcse

[Cody Garver (codygarver)]

It's also constantly creating temporary files in /tmp/

[Глоба Антон (globa3334)]

Application Center freezes when you select some applications.

Reproduced in the following way: Start Application Center, open the "Internet" category, go to SSh AskPass application. After that, the application center freezes and consumes a lot of CPU. It looks like Loop.

PS Strace attached.

[Danielle Foré (danrabbit)]

This seems to be an upstream issue in PackageKit and only occurs when adding 3rd party repositories that generate errors. Bumping to the next milestone

[David Heidelberg (okias)]

I can confirm that packagekitd easy between 50-100% of one CPU almost permanently, until gets killed.

Not sure if there is connection with appcenter (it behaves this way from Loki start).
Not sure if any files created in /tmp, not spotted.

Log is filled with this in same interval, is it OK?

After manually killing it, spam stops.

[Danielle Foré (danrabbit)]

Again this only occurs if you have added 3rd party software sources that produces security errors. In your case the problem is the OpenSuse repository as indicated by this line:

http://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Ubuntu_16.04/Release.gpg: Signature by key F9EA4996747310AE79474F44977C43A8BA684223 uses weak digest algorithm (SHA1)

This error doesn't occur in the default installation and there's nothing we can really do about it in elementary OS or AppCenter (afaik)

[NoOne (1noname)]

If it's upstream related, why doesn't this happen also in Ubuntu ?

[David Heidelberg (okias)]

Well, it generate "error", that's OK.

BUG is, that packagekitd use 100% CPU instead of reporting error or ending job...

[Danielle Foré (danrabbit)]

Guys please stop spamming this report. The issue is marked as "confirmed".

[Artemis Entreri (mongodada)]

I had my packagekitd running 15%-25% of the CPU.
I checked my sources.list and saw that I had duplicate entries of the following sources

deb http://se.archive.ubuntu.com/ubuntu/ xenial universe
deb http://se.archive.ubuntu.com/ubuntu/ xenial-updates universe
deb http://se.archive.ubuntu.com/ubuntu/ xenial multiverse
deb http://se.archive.ubuntu.com/ubuntu/ xenial-updates multiverse

Don't know why, but after deleting the duplicates the packagekitd finished it's work and stopped.

[Tae Hyoun Park (hyoun)]

Hello,

I do not have any 3rd party software with security errors:

But packagekitd always uses up CPU from startup. Killing and restarting appcenter stops it.

[Tae Hyoun Park (hyoun)]

I discovered that the command "$ appcenter -s" causes the program to continuous search for updates: in the updates tab, the "searching for updates..." prompt repeatedly appears.

Starting appcenter through "$ appcenter" does not do this.

Also, this error message is displayed in terminal in both cases:

[FATAL 01:30:51.956022] Client.vala:250: The package id's '' are not valid

[davidak (davidak)]

I created a bugreport upstream: https://github.com/hughsie/PackageKit/issues/175

[davidak (davidak)]

>You need to file this downstream with elementary OS as we do no QA on that distro whatsoever and I don't know what downstream patches have been used. [...]

Someone has to debug it...

[Tae Hyoun Park (hyoun)]

From gnome-session-properties, I've simply set the appcenter to not launch at startup. This is not a fix, but has eliminated high CPU usage for me.

One could also change the command 'appcenter -s' to 'appcenter' and it should as well, I have not tried this.

[davidak (davidak)]

Is this possibly solved?

I had no problem the last times i booted.

[Tae Hyoun Park (hyoun)]

I have had no problems with this for a while as well :)

[Félix Brezo (febrezo)]

No it is not solved. I had to manually remove the repositories from /et kc/apt/sources.list.d/ whose GPG keys were missing. This seemed to be the error. This has prevented this from happening for me. However, it seems not to be an AppCenter as other Ubuntu users where experiencing it too.

[Corentin Noël (tintou)]

If you find more issues with packagekit itself, you might want to report issues on the original bugtracker : https://www.freedesktop.org/software/PackageKit/

[Rodrigo (rodrigolopezguerra)]

As point it out in several comments , fixing the missing GPG solved the problem for me .
In my case was the new skype version :

# make sure you have 'apt-transport-https' installed
dpkg -s apt-transport-https > /dev/null || bash -c "sudo apt-get update; sudo apt-get install apt-transport-https -y"
curl https://repo.skype.com/data/SKYPE-GPG-KEY | sudo apt-key add -
echo "deb [arch=amd64] https://repo.skype.com/deb stable main" | sudo tee /etc/apt/sources.list.d/skype-stable.list
sudo apt-get update
sudo apt-get install skypeforlinux -y

[Emil (tanoff)]

Thanks Rodrigo, it worked for me (elementary os loki)

[Martin Janiczek (janiczek)]

For those that have this problem, only not with Skype but with AppCenter,
do this:

curl http://packages.elementary.io/key.asc | sudo apt-key add -
sudo apt-get update

[indigocat (indigocat)]

#24 worked for me, immediate CPU usage drop;
CPU was idling at 60°C, now dropped to the usual 38-40°C range as with kernel 4.4 in xenial.

Thanks for the tip!
