Describe the bug

dotnet Tools no longer working with the most recent update to runtime (worked a few days ago and stopped... issue appears to be tools can't find the framework, even though the framework exists)
Platform Ubuntu 22.04.1 LTS x86_64
Multiple tools having issues (dotnet-updater seqcli)

Anything else?

Applications that I've written on my own work fine when executing dotnet {project}
dotnet tools don't appear to want to execute with the dotnet in front of it and will show the above error when running them individually.

This is probably the same problem as this one: dotnet/runtime#79237
There are some workarounds and future fixes described in that issue.

Thank you so much! setting DOTNET_ROOT=/usr/lib/dotnet seams to have corrected the issue on my local machine

[KennethHoff]

Using the dotnet-install script adds it to $HOME/.dotnet/ by default. In that case you'll need to do the following instead:

DOTNET_ROOT=$HOME/.dotnet/

Closing as the Ubuntu packages are now updated and should not cause this failure anymore. @KennethHoff coment is correct is you use the install script instead.
