    @Pilot6 (and others who voted for this question being off-topic): This is not specific to a particular Ubuntu version. It affects all users of Google Chrome on Ubuntu who have the Chrome repository enabled. Mar 5 '16 at 3:43

    @GunnarHjalmarsson what's the point of re-opening, since it's a dupe of askubuntu.com/questions/724093/… anyway?

    I can't see, why this should be a duplicate of the mentioned question. The source of the problem is the same, but the context is different (64 vs 32 bit).

I tracked down offending repo (any for Google chrome in this dir)

cd /etc/apt/sources.list.d
grep chrome * | grep -v amd64

or more generally

grep -r google  /etc/apt | grep -v amd64 

Now do same as below for each repo file which matches above

cat /etc/apt/sources.list.d/google-chrome-unstable.list

# You may comment out this entry, but any other modifications may be lost.
deb http://dl.google.com/linux/chrome/deb/ stable main

SOLUTION : limit to just 64 bit by introducing the [arch=amd64]

deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main

ROOT CAUSE : Google dropped support for 32-bit Chrome on Linux triggering an error when updating apt in 64-bit systems (with multi arch enabled) ... details here : http://www.omgubuntu.co.uk/2016/03/fix-failed-to-fetch-google-chrome-apt-error-ubuntu

To confirm you are using 64 bit ubuntu with multiarch enabled issue

dpkg --print-foreign-architectures

if it says


then you have added 32 bit support, this will list your native arch ... issue

dpkg --print-architecture 

if you are native 64 you will see this output so do SOLUTION shown above


Here is the command to remove multi architecture ( only if you have no 32 bit applications )

sudo dpkg --remove-architecture i386

    This answer works very well (thank you!), however the file that needs to be edited (in your example /etc/apt/sources.list.d/google-chrome-unstable.list) is automatically configured on a regular basis, so the fix is written over and needs to be added over and over again. Any suggestions to overcome this?

  • How to list i386 architectures? Nov 20 at 10:03

(this solution is for Ubuntu Bionic Beaver)
First, shame on Google for letting this issue linger so long!!

Here's how to fix it:
As already mentioned above, editing files in /etc/apt/sources.list.d seems to work... but only temporarily. The next day, the problem is back.

Here's why:

The file /etc/cron.daily/google-earth-pro runs daily and overwrites what you have in /etc/apt/sources.list.d/google-earth-pro.list.

To fix it once and for all, edit /etc/cron.daily/google-earth-pro.
Find this line:

REPOCONFIG="deb http://dl.google.com/linux/earth/deb/ stable main"

...and change it to:

REPOCONFIG="deb [arch=amd64] http://dl.google.com/linux/earth/deb/ stable main"

    For immediate change for Google Earth, it might be worth editing the files google-earth-pro.list and google-earth-pro.list.save.

    Interesting, I did this AND the sources file still gets re-written.

    /etc/apt/sources.list.d/google.list covers google-chrome-stable, google-chrome-beta and google-chrome-unstable. cat /opt/google/chrome-beta/cron/google-chrome-beta | grep "REPOCONFIG=". cat /opt/google/chrome-unstable/cron/google-chrome-unstable | grep "REPOCONFIG=". All three point to stable.

deb http://dl.google.com/linux/chrome/deb/ stable main


deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main

in each of

  • /etc/apt/sources.list.d/google-musicmanager.list
  • /etc/apt/sources.list.d/google-musicmanager.list.save
  • /etc/apt/sources.list.d/google-musicmanager.list.distUpgrade

seems to fix the issue for Google Music Manager for Play Music too. Not sure if it will revert these changes at some point as the files are automatically configured.

    for me file to change was /etc/apt/sources.list.d/google.list

Although Google has fixed this issue for Chrome, it still appears for e.g. Google Earth.

Adding [arch=amd64] fixes the issue, but it needs to be added over and over again.

After making the file immutable as proposed by a webupd8 article and running into issues because of that, my current solution is to add a cronjob to apply the fix automatically once every hour:

~$ sudo crontab -e

0 * * * * sed -i 's/^deb http/deb [arch=amd64] http/' /etc/apt/sources.list.d/google-earth.list

(Replace google-earth.list if necessary).

  • Out of curiosity what keeps changing this file? In my experience, apt sources files don't get changed by themselves

  • Sergio Rus reckons that Google eventually fixed it for Chrome such that your one-time change would be preserved over updates. Jul 11 '18 at 23:25

Though this question has been marked solved, I was unable to solve this issue with any of the above answers. I used an another method. Go to 'software & updates' > ubuntu software > download from > select best server. Now wait for some time for the system to find it out. Once this gets done, try your command again. This worked for me.


I add my 2 cent. Sorry If I have a Debian 10 and not an Ubuntu, but my answer is in-topic.

I had the same problem due to mariadb repo. It was added to sources.list as

deb [arch=amd64,i386,ppc64el] http://ftp.nluug.nl/db/mariadb/repo/10.3/debian buster main

I simply removed i386 and ppc64el

deb [arch=amd64] http://ftp.nluug.nl/db/mariadb/repo/10.3/debian buster main

Even if this question is marked solved, for me, on Ubuntu 18.04, changed a line in /etc/apt/sources.list from deb http://dl.google.com/linux/chrome/deb/ stable main to deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main.

There was no file named /etc/apt/sources.list.d/google-chrome-unstable.list. Making the same changes in /etc/apt/sources.list.d/google-chrome.list gave warnings saying that target package is configured multiple times. (in sources.list and google-chrome.list)


Change my source list

deb https://download.mono-project.com/repo/ubuntu stable-focal main


deb [arch=amd64] https://download.mono-project.com/repo/ubuntu stable-focal main
