Core: Error while installing .net core 2.2

Issue Title

I was following the procedure but ran into an error...

sudo apt-get install aspnetcore-runtime-2.2
Reading package lists... Done

Which distro did you try?
Does it happen on clean VM as well?

@dagood can you please help here?

@irreverencieux - could you run sudo apt-get install dotnet-runtime-deps-2.2? This should tell us exactly which system dependency is unable to be installed.

I had that same issue: https://github.com/dotnet/core/issues/2381

sudo apt-get update && sudo apt-get upgrade the re-run, that did the trick. From https://askubuntu.com/questions/1065231/dpkg-deb-error-archive-has-premature-member-control-tar-xz-before-contr/1065237#1065237

Possibly its the libicu57 package that won't install. Thats what happens to me. I have the same error on this thread.

Package libicu57 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

You could try using snap to install the beta.

It's libicu57 that won't install.

Original poster's issue didn't have enough info to follow up on--closing as stale.

Thanks all for the input! To sum up:

• cjvalenzuela's tip to use sudo apt-get update && sudo apt-get upgrade (https://github.com/dotnet/core/issues/2381) may have fixed it, but we don't know. I've asked Lee in that thread if we can add something to the install page to inform people about this issue.
• SuperTal3's libicu issue is tracked at https://github.com/dotnet/core/issues/2416 (which has significantly more detail than this issue, thanks 😄). We don't know if it's the same issue, and if it is, we don't need this duplicate open.
