Install issues - File has unexpected size and Some index files failed to download

General
1

I’m attempting to install Docker on an Ubuntu Linux VM (18.04). I’m following the instructions listed on docs docker com/install/linux/docker-ce/ubuntu/docs docker site.

I’ve installed the necessary packages and repo gpg key. I’ve added the repo location to the /etc/apt/sources.list with:

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

And I have confirmed that it is correct in the file. When I attempt a sudo apt-get update I get the following errors (NOTE: all the URLs below are prefaced with https but because I’m a new user, I can only submit two links in my post so I manually removed them):

This looks like it’s something on the repo end unless I’m missing something.

Thanks!

Thanks

I also have the same error for an ARM64 device. Here’s the error:

Exact same error here. apt clean, and trying edge rather than stable didn’t help.

I’m not sure if my problem is the same but I can’t install it on CentOS Arm64. If it helps, I can’t download (https://download.docker.com/linux/centos/7/aarch64/stable/repodata/a4c80c0b37f525089891f5ba0712d9ee3e42d56b07fe40bf64f06c761ff71dc2-primary.sqlite.bz2) even though it appears to be there when browsing the parent directory.

Dont think the fix worked, went from
File has unexpected size (9417 != 7889)
to
File has unexpected size (9051 != 7889).

I’m having this problem still as well, what’s the status of the fix?

I had the same issue but is working now
Debian 10

working on ubuntu 18. needed to sudo apt autoremove && sudo apt clean first.
