Runtime: Snap installer - ubuntu 20.04 - libc musl

[sharkguto]

Today after a snap refresh and update the dotnet-sdk snap package, i am not able to run it anymore.

ERROR:

/snap/dotnet-sdk/95/dotnet: error while loading shared libraries: libc.musl-x86_64.so.1: cannot open shared object file: No such file or directory

I tried to install musl and create a symlink , without success.... someone can help me???

using last stable version
dotnet-sdk 3.1.401 from Microsoft .NET Core (dotnetcore✓) refreshed

This is weird, to my knowledge Ubuntu uses glibc, not musl, so I don't know why it would be looking for that in this case.

@leecow is it possible something weird happened like the snap ended up containing linux-musl-x64 rather than linux-x64?
I haven't poked at this myself.

I wasn't able to get snapd working (in docker), but did find out how to download the dotnet-sdk snap raw via advice in https://forum.snapcraft.io/t/download-snap-package/14212/5, and yeah, the dir structure 7zip shows me is a little weird, but it's clear from shared\Microsoft.NETCore.App\3.1.7\Microsoft.NETCore.App.deps.json and some other places that it's linux-musl-x64 rather than linux-x64.

It seems like the snap will have to be fixed up to contain linux-x64 binaries and updated.

Thanks for the troubleshooting dagood! My team got a big problem with this bug inside snap package. I hope someone can fix it soon.

Grateful for your attention

@rbhanda to take a look at the build.

[leecow]

Rolled back the 3.1 offerings in the Snap store to 3.1.302 until this gets worked out.

[rbhanda]

We have published the snap packages again. This should be resolved now

[dagood]

@rbhanda I noticed that 3.1.6 resolved known issue backlink, but doesn't 3.1.401 actually contain a 3.1.7 runtime so it should be posted there instead?

[rbhanda]

It seems I updated wrong issue. I added the list of issues in our August post

[sharkguto]

@rbhanda now its working fine. thanks

Closing the issue as it was resolved.
