Bug report: "VERSION_CODENAME" field absent in os-release file

[iamhyc]

Until Deepin v20 (1003), lsb_release -a would tell n/a for "Codename" section.

But actually, it should output "apricot" for Deepin v20, where /usr/lib/os-release file is to blame for the absence of "VERSION_CODENAME" field.

This section may be helpful when someone (saying a friend of mine :) tries add-apt-repository on Deepin, but finds confusing "No template for Deepin/n/a" and wonders what's "/n/a" for.

@felixonmars Maybe he can help you explain.

You can't use add-apt-repository to add ubuntu repositories on Deepin, we are based on Debian.

Is there any other use for VERSION_CODENAME?

As what I have claimed, someone would like to try for a luck and found the confusing "/n/a" postfix after "Deepin".

Not sure what is the codename for v20.3, but back in 2020, you did have "apricot" as the codename for the repo.

刚看了眼论坛，不还是apricot吗；虽然这个是optional，但可以加上吗，至少看着好看？

Yes, apricot is also the codename of v20.3 now. I want to know if there are other apps that read VERSION_CODENAME, if not, there is no need to add it.

Not apps, but third-party repos do. For example, nodejs, nodesource/distributions#638.

The current solution now is still to fake yourself as Debian10.
