.net core 8: version `GLIBCXX_3.4.29' not found in Ubuntu 23.10

Question

I'm trying to apply a migration dotnet ef database update But I only see a message:

Failed to load /usr/lib/dotnet/host/fxr/8.0.2/libhostfxr.so, error: /snap/core20/current/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.29' not found (required by /usr/lib/dotnet/host/fxr/8.0.2/libhostfxr.so)
The library libhostfxr.so was found, but loading it from /usr/lib/dotnet/host/fxr/8.0.2/libhostfxr.so failed
  - Installing .NET prerequisites might help resolve this problem.

command strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX returns me:

So, I've already installed GLIBCXX_3.4.29 Also, I tried different update|upgrade|build-essential installations options, but useless. Could you help me?

So, sudo snap refresh (update to core22) and dotnet tool update dotnet-ef --global accomplished the deal! Omajid, thanks for assistance!
