@jonathanpeppers Is there a maui-android workload for Linux? |
|
There is for jammy. We are using 22.04 right now and it can be installed without any issue. |

@klemmchr you're using the distro-built SDKs, not the MS-provided SDKs, right? In that case you're hitting dotnet/source-build#3242. We're working with the MAUI teams to make their workloads compatible with the Source-Built SDKs (which the distros use) but for now there's not really a great workaround that doesn't involve mucking around in your SDK install. Please follow that issue for updates. |

An alternative is to install the Microsoft build of the SDK manually from the .tar.gz as detailed in https://learn.microsoft.com/en-us/dotnet/core/install/linux-scripted-manual#manual-install |

@baronfel I can reproduce this issue using the MS-provided SDKs. This is a sample Dockerfile for jammy (working): FROM ubuntu:jammy

RUN dotnet workload install maui-androidI cannot say for sure that the MS-provided SDKs are even installed on noble. According to the docs there is no Microsoft feed for noble. Installing .NET via manual install is not an option to me. I need a solution where the latest SDK gets installed automatically without manual configuration from my side. |
Correct, the packages.microsoft.com repo for Ubuntu 24.04 doesn't contain 8.0 SDKs so you're installing from Ubuntu's repo: https://packages.microsoft.com/ubuntu/24.04/prod/pool/main/d/
You could use the dotnet-install.sh script which handles installing the latest version: https://learn.microsoft.com/en-us/dotnet/core/install/linux-scripted-manual#scripted-install |
Why is Microsoft not publishing the 8.0 SDKs in their repo, especially when the distro-build SDKs are not suited for installing certain workloads?
Using magic install scripts in Dockerfiles is heavily discouraged since it poses a security risk and makes the installation intransparent. |
There's more background in dotnet/core#9258. I wasn't involved in the discussions so I'm not sure people were aware of the MAUI workloads limitation.
You can read the source of the script, it essentially downloads and unpacks the .tar.gz, which is why I suggested the manual install 😄 But anyway this was meant to give a workaround, the real fix is putting the workload manifests into source-built SDKs: dotnet/source-build#3242 |
