[SOLVED]Cannot Install docker-ce on Debian Stretch

General
1

Hi,

I’m following this reference: https://docs.docker.com/install/linux/docker-ce/debian/ for installing docker-ce on my debian stretch desktop.

I prefer “Install Using the Repository” and I have GOOD results following steps 1-5. The problem came when I do an apt-get update I receive this error:

Err:12 https://download.docker.com/linux/debian stretch/stable amd64 Packages
gnutls_handshake() failed: Public key signature verification has failed.
....
W: The repository 'https://download.docker.com/linux/debian stretch Release' does not have a Release file.

I tried to look for solutions on the net and in this forum but I did not see any.

After a while, I realized I can do another install using the section “Install from a Package”. So I go the the link https://download.docker.com/linux/debian/ and look for the .deb file my distro but I don’t see any.

As for the other methods- I prefer not to use them as they have a lot of cautions to mind.

Appreciate any help here.

Thanks,

Interesting…

I just did an installation on another Debian Stretch desktop using the instructions above and for some reason, it worked just like that.

Although they are both Debian Stretch desktops, I know there must be some difference but I’m not that advance to know how to troubleshoot this. Nor do I have any idea where to begin.

There is one thing I did DEFFERENTLY in the previous install – in step 3 I ACCIDENTALLY execute the command

curl -fsSL https://download.docker.com/linux/debian/gpg | sudo apt-key add -

on a NON-ROOT shell and I’m guessing the sudo part did not execute because of an error message.

$ sudo apt-key fingerprint 0EBFCD88
pub   rsa4096 2017-02-22 [SCEA]
  9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
uid           [ unknown] Docker Release (CE deb) <docker@docker.com>
sub   rsa4096 2017-02-22 [S]

I have uid [ unknown] included but not found in the instruction. What is this and how can I troubleshoot this.

Thank you

This is really getting on my nerves. I’m now away from the desktop. And just installed docker on a third debian desktop successfully.

apt-get update

looks into a lot of docker related URLs. On the third successful install, apt-get update only look into one docker url. I can’t list the urls as am now away from the desktop. But this is a good way of keeping tabs on my progress.

Nope, I still don’t have any solution for my issue. Can someone point me to where I can possibly get a solution to this issue?

Do I need to provide more information to help solve this issue. Please help.

Thank you,

I visited this site for a solution

# dpkg -l | grep libgnutls ii libgnutls-deb0-28:amd64 3.3.8-6+deb8u7 amd64 GNU TLS library - main runtime library rc libgnutls-deb0-28:i386 3.3.8-6+deb8u7 i386 GNU TLS library - main runtime library ii libgnutls-openssl27:amd64 3.5.8-5+deb9u3 amd64 GNU TLS library - OpenSSL wrapper ii libgnutls30:amd64 3.5.8-5+deb9u3 amd64 GNU TLS library - main runtime library ii libgnutls30:i386 3.5.8-5+deb9u3 i386 GNU TLS library - main runtime library

It looks like I have two (2) versions of libgnutls when I try to remove libgnutls-deb0-28

So I try to remove one of them - the older one with some errors that prevents me from completely removing the package:

[code]# apt-get remove --purge libgnutls-deb0-28

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

The following packages have unmet dependencies:
libcurl3-gnutls : Depends: librtmp1 (>= 2.4+20131018.git79459a2-3~) but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.[/code]

Using synaptic - I looked into BROKEN packages. Resolve this issue by deleting these packages and now I don’t get error message using apt-get update for the docker repository.

I tried these steps to install docker on Parrot OS,

Uninstall Old Docker:

sudo apt-get remove docker docker-engine docker.io containerd runc

Setup docker repo:

sudo apt-get update

sudo apt-get install ca-certificates curl gnupg lsb-release

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

 echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

But after this step when I run the command “sudo apt update” I was getting the error
“Err:4 Index of linux/debian/ n/a Release
404 Not Found [IP: 13.249.208.21 443]”

then I run the command this command: $$(lsb_release -cs) to check the release version but I got “-bash: n/a: No such file or directory”

so I put “bullseye” in place of $(lsb_release -cs)

Install Docker:
sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io
