Resolve discrepancies with dependency libraries between docs and code

[mthalman]

The documentation at https://github.com/dotnet/docs/blob/master/docs/core/linux-prerequisites.md has a section on Linux distribution dependencies. The packages that are listed here don't line up with the packages that are specified in the packaging runtime deps.

For example, the doc shows these required libraries for Ubuntu:

• liblttng-ust0
• libcurl3 (for 14.x and 16.x)
• libcurl4 (for 18.x)
• libssl1.0.0
• libkrb5-3
• zlib1g
• libicu52 (for 14.x)
• libicu55 (for 16.x)
• libicu57 (for 17.x)
• libicu60 (for 18.x)

But the Debian runtime deps shows these:

• libc6
• libgcc1
• libgssapi-krb5-2
• libstdc++6
• zlib1g
• libssl*
• libicu*

Thanks for your feedback @mthalman. @leecow Can you please take a look at this issue for Linux prereqs?

The problem is that while packagename* works when the dependency is expressed in a deb, doing the same from a bash script or directly with the package manager does not work (that I can tell anyway).

For example, attempting apt-get install libicu* will literally install every package that starts wtih "libicu".

I'm all for it if there's a way to express this in the docs to simplify things a bit.

The * wasn't meant to be the literal value used in a shell command; it was merely meant to indicate multiple versions (https://github.com/dotnet/core-setup/blob/fd3b3421d7b901aaac28ad34e63b6480f88973d3/src/pkg/packaging/deb/package.targets#L327).

This issue is somewhat related to https://github.com/dotnet/coreclr/issues/26303. In an ideal world, we'd have one master list of native dependencies. Documentation could be updated programatically by reading from this master list.

This issue has been closed as part of the issue backlog grooming process outlined in #22351.

That automated process may have closed some issues that should be addressed. If you think this is one of them, reopen it with a comment explaining why. Tag the @dotnet/docs team for visibility.

[mthalman]

Reopening because this is still relevant. There is a larger effort to better manage the descriptions of native dependencies at https://github.com/dotnet/core/issues/5651.
