I'm using .net core on Linux specifically Manjaro 20.2.1, I'm learning .net core, I want to use EF commands, but it's slightly different how its works on Linux, I had installed the dotnet-ef tool whit this command:

dotnet tool install --global dotnet-ef --version 5.0.3

So when I try to run donet ef throws me this error:

/home/$USERNAME/.dotnet/tools/dotnet-ef: /snap/core18/current/lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by /usr/lib/libstdc++.so.6)

But it seems that the GLIBC version that it's installed on my distro is: 2.33-3, and its seems that the version that it's looking for it's specifically the 2.33.

How I can get rid of this problem?

It seems that something in dotnet depends on GLIBC 2.33 but dotnet is tied to core18 which is using GLIBC 2.27.

  • Hi, I just runt the command but ist'n work throws me this log: /snap/core18/current/lib/x86_64-linux-gnu/libc.so.6:: cannot open `/snap/core18/current/lib/x86_64-linux-gnu/libc.so.6:' (No such file or directory) – g14wx Feb 28 '21 at 06:11
  • Did you forget to remove a trailing colon? Try this `file /snap/core18/current/lib/x86_64-linux-gnu/libc.so.6` – Danil Kondratiev Feb 28 '21 at 08:09
  • this is the output of the last command: /snap/core18/current/lib/x86_64-linux-gnu/libc.so.6: symbolic link to libc-2.27.so – g14wx Mar 01 '21 at 21:03

    Oh I mean it's not a fix. My theory is `dotnet` depends on the system's `Glibc 2.32` and to fix it your system must have `glibc 2.32` but Manjaro comes with `2.33-4` on the stable branch. Apparently `dotnet` aims at Ubuntu 20.10 with its `glibc 2.32` (interesting Ubuntu 20.04 has `2.31`, so the snap won't work on it?) – Danil Kondratiev Mar 02 '21 at 20:11
  • Oh I see, Do you think if I download dotnet-runtime from arch repo, could it work? – g14wx Mar 03 '21 at 05:43
  • Hey, thank you,it was that you suspect, the snap dotnet package, doesn't really work well with manjaro, so I uninstall it and install the one from the repos, and now its working! – g14wx Mar 03 '21 at 06:56
  • Had the same error on a snap that is based on core 20 – Guy Luz Mar 27 '23 at 16:44
