I tried to install Docker on Kubuntu 19.10.

I used these steps to install: https://docs.docker.com/install/linux/docker-ce/ubuntu/

Answer 1

If the from @vavalm did not work either, check that you have installed ubuntu amd64. There is a chance that you have installed the Ubuntu version i384 instead

Answer 2

Edit the file : /etc/apt/sources.list

Look for repo entry :

deb-src [arch=amd64] https://download.docker.com/linux/ubuntu eoan stable

Changing it to:

deb-src [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable 

resolved the issue for me

Answer 3

It's not the cleanest way to do it I guess, but I had the same problem as you and I changed:

$ sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

to

$ sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   bionic \
   stable"

because

$(lsb_release -cs)

returns "eoan" (the name of the latest ubuntu version, currently 19.10) and it seems to cause problems. Replacing this with "bionic" (ubuntu 18.10) worked perfectly for me, and I still have no problems 4 months later.

Don't forget to open "/etc/apt/sources.list" and comment-out/delete the line:

deb-src [arch=amd64] https://download.docker.com/linux/ubuntu eoan stable

to avoid conflicts. (You added this with the first command you entered in this process.)

Answer 4

The official docker documentation recommend to use

  $ sudo add-apt-repository \
       "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
       $(lsb_release -cs) \
       stable"

for Ubuntu 19.10 which seems that doesn't contain 'containerd.io' package yet.

Remove the previously added repository using add-apt-repository --remove :

$ sudo add-apt-repository --remove \
       "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
       $(lsb_release -cs) \
       stable"

and add the one used for bionic (18.10) Ubuntu release:

$ sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   bionic \
   stable"

After this, update and install docker:

$ sudo apt-get update
$ sudo apt-get install docker-ce docker-ce-cli containerd.io
