RUN dotnet publish Jellyfin.Server --configuration Release --output="/jellyfin" --self-contained --runtime linux-arm64 -p:DebugSymbols=false -p:DebugType=none

[GangWang01]

@liuqinghongl from the provided info I guess Jellyfin.Server is in Jellyfin that guides how to build from source. The build happened on linux. I tried to reproduce this issue on linux using both non-container image and container image following the guide. Build succeeded. I couldn't reproduce this issue. The used dotnet version was 8.0.401.

If my guess is wrong, can you provide detailed info to help reproducing the issue including the following?

• The source code or an example project to produce.
• Steps to reproduce.
• dotnet info - run the command dotnet --info to get
• OS: Linux, Windows or macOS.
