I did an upgrade of Ubuntu on WSL from 18.10 to 19.04 with do-release-upgrade. 

$ cat /etc/os-release
NAME="Ubuntu"
VERSION="19.04 (Disco Dingo)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 19.04"
VERSION_ID="19.04"
HOME_URL="https://www.ubuntu.com/"
SUPPORT_URL="https://help.ubuntu.com/"
BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
VERSION_CODENAME=disco
UBUNTU_CODENAME=disco

But now I notice that repositories/sources.list are still pointing to cosmic.

$ grep -li cosmic /etc/apt/sources.list /etc/apt/sources.list* /etc/apt/sources.list*/*
/etc/apt/sources.list
/etc/apt/sources.list
grep: /etc/apt/sources.list.d: Is a directory
/etc/apt/sources.list.distUpgrade
/etc/apt/sources.list.save


$ grep -li disco /etc/apt/sources.list /etc/apt/sources.list* /etc/apt/sources.list*/*
grep: /etc/apt/sources.list.d: Is a directory

So I guess something must have failed during the upgrade that I didn't notice.

How can I dig out any upgrade errors and fix them?
Where can I find the sources list for 19.04?

  • You need to pass recursive option to grep (grep -r) to search inside /etc/apt/sources.list.d directory - that is grep -lir cosmic /etc/apt/sources.list /etc/apt/*.list /etc/apt/sources.list.d/*.list. And please note that 19.04 is disco, but 18.10 is cosmic. – N0rbert May 04 '19 at 09:15
  • @N0rbert - I guess there are no sub-folders to recurse in /etc/apt/sources.list /etc/apt/*.list /etc/apt/sources.list.d/*.list. And the issue itself is that I cannot find disco in sources.list – nariknahom May 04 '19 at 09:22
  • by the way /etc/apt/sources.list.d/ is a folder and we combine both files and this directory in grep command. I do not know details about WSL, but on regular Ubuntu it is allowed to install all upgrades to cosmic and then change all occurrences of cosmic to disco in all *.list files, followed by sudo apt-update with sudo apt dist-upgrade. – N0rbert May 04 '19 at 09:26

Where can I find the sources list for 19.04?

Steps required:

  • Run these commands in WSL console only. Otherwise, the file/folder permissions will be incorrect. Also, use chmod to correct any file permission.
  • Open Ubuntu cloud image website: https://cloud-images.ubuntu.com/releases/19.04/release/
  • Download the ubuntu-19.04-server-cloudimg-amd64-root.TAR.XZ file. Because it is smaller than others ;)
  • Extract the /etc/apt folder with tar -xvf ubuntu-19.04-server-cloudimg-amd64-root.tar.xz etc/apt command. Do not add the leading slash in the folder path.
  • Now copy the sources.list file or any other required files as you need.

If you just want to update your existing sources.list to point to the new distro after you've already upgraded, you can do this:

Warning: Tread carefully! Always backup your file first.

sudo sed -i "s/cosmic/$(lsb_release -cs)/" /etc/apt/sources.list

The form of the sed command is: "s/<old value>/<new value>/"

To backup your file first, you can simply do: sudo cp /etc/apt/sources.list ~/

You can also see this answer for an idea of what the sources.list should look like:

What is the correct output of cat /etc/apt/sources.list?

By following the @Biswaprio's answer, here I put the content of sources.list file for ubuntu 19.04 so that others don't need to go through the whole process again.
