/usr/share/dotnet/sdk/3.1.101/NuGet.targets(123,5): error : Unable to obtain lock file access on '/tmp/NuGetScratch/lock/b19d3901039706ea82571abad7c98ec690508d4b' for operations on '/home/limup/Documents/Projetos/Limup/salao/obj/salao.csproj.nuget.cache'. This may mean that a different user or administator is holding this lock and that this process does not have permission to access it. If no other process is currently performing an operation on this file it may mean that an earlier NuGet process crashed and left an inaccessible lock file, in this case removing the file '/tmp/NuGetScratch/lock/b19d3901039706ea82571abad7c98ec690508d4b' will allow NuGet to continue.

Restore failed.
Post action failed.

Obs

I tried to make fixes in dotnet store, but got the same error.

I did not have this problem with dotnet sdk 2.0.

    Welcome to Stackoverflow in English. As the name suggests, the official language used here is Portuguese. So, could you please translate your question? If you prefer, you can also ask the same question on the Stackoverflow website.

  • Sure! Done the translation.

  • If you read the error message to the end, you will find: This may mean that a different user or administator is holding this lock and that this process does not have permission to access it. If no other process is currently performing an operation on this file it may mean that an earlier NuGet process crashed and left an inaccessible lock file, in this case removing the file '/tmp/NuGetScratch/lock/b19d3901039706ea82571abad7c98ec690508d4b' will allow NuGet to continue.

  • then just need to remove the file

Gentlemen, you can resolve the situation with the following commands::

export TMPDIR=/tmp/NuGetScratch/

and

mkdir -p ${TMPDIR}

Thank you all.
