Distributions: Your distribution, identified as "focal", is not currently supported

[ceciliazcx]

I got Your distribution, identified as "focal", is not currently supported in my dockerfile when deploy to Azure.
The detail error is as following, could I know how to fix it?

```## Populating apt-get cache...

  Your distribution, identified as "focal", is not currently supported, please contact NodeSource at https://github.com/nodesource/distributions/issues if you think this is incorrect or would like your distribution to be considered for support```

@ceciliazcx

I had FROM ubuntu:latest in my Dockerfile which was causing the above error.

Changing it to FROM ubuntu:16.04 fixed it so I presume its an incompatibility issue with Ubuntu 20

[igsu]

Scripts are set to support Ubuntu 20.04, @ceciliazcx please confirm this is still an issue.

[paulmillr]

@igsu still happens

I see a similar issue with https://deb.nodesource.com/setup_12.x:

Your distribution, identified as "Ubuntu Focal Fossa (development branch)", is a pre-release version of Ubuntu. NodeSource does not maintain official support for Ubuntu versions until they are formally released. You can try using the manual installation instructions available at https://github.com/nodesource/distributions and use the latest supported Ubuntu version name as the distribution identifier, although this is not guaranteed to work.

@mateuszbrycki @paulmillr check that you aren't (somehow) using a development version of Ubuntu. The script is looking specifically for the word "development" in the name of the OS release. You can check this yourself with the lsb_release tool (apt install lsb-release if its missing).

Successful (working) example:

root@4a452b8c2aba:/# lsb_release -d -s
Ubuntu 20.04 LTS

[paulmillr]

@bryanlatten yeah it's not development, it's lts

[igsu]

@ceciliazcx please note that the Node version that you are trying to install is deprecated:

curl -sLf -o /dev/null 'https://deb.nodesource.com/node_11.x/dists/focal/Release'

Please try again with the currently supported versions: 10, 12, 13 and 14...

Please provide more information about your environment or any custom network setup (some users experience this issue when they are behind a proxy #904 - see comment)

[paulmillr]

yup, using socks proxy. apt-get still works though.

[igsu]

@paulmillr check this comment.

[paulmillr]

@igsu the issue is not "using proxies". It's useless error. If proxies aren't supported, nodesource should communicate this.

@paulmillr you can check our FAQ, that is the first question there:

I removed -E flag and it works now.
eg:

sudo curl -sL https://deb.nodesource.com/setup_14.x | sudo bash -
