I've verified that it does install and run fine on 18.04 so need to figure out what dependency you're missing. Try apt install dotnet-runtime-deps-2.1 and let's see if that gives us a clue.

Could you also provide the output from uname -a?

The issue is with package liblttng-ust0:

Perhaps the difference is I'm using Ubuntu 18.04.1, rather than 18.04.0?

This appears to be a dup of https://github.com/dotnet/core/issues/1822 (also https://github.com/dotnet/core-setup/issues/4417). The workaround suggested in those issues works for me as well:

sudo add-apt-repository universe

Closing this issue then as it is already being tracked somewhere else. The core-setup issue seems the more appropriate one to me.

Ubuntu 18.04 actually has libicu60

Had the same problem on Ubuntu 16.04 and I guess the solution is similar regardless:

sudo apt-get remove libicu57
wget http://security.ubuntu.com/ubuntu/pool/main/i/icu/libicu55_55.1-7ubuntu0.4_amd64.deb
sudo dpkg -i libicu55_55.1-7ubuntu0.4_amd64.deb
wget http://security.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.0.0_1.0.2g-1ubuntu4.15_amd64.deb
sudo dpkg -i libssl1.0.0_1.0.2g-1ubuntu4.15_amd64.deb
sudo apt-get install dotnet-sdk-2.2
