libicu not found FailFirst in Opensuse Tumbleweed

[Lu4nScr1pt1ng]

I’m encountering an issue when trying to run an Azure Function locally. The following error is being generated:

1>Microsoft.Azure.WebJobs.Script.ExtensionsMetadataGenerator.targets(37,5): Warning: Couldn't find a valid ICU package installed on the system. Set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support.

Here’s the screenshot:

I’m using OpenSUSE Tumbleweed:

.NET 8.0, along with the following library versions:

<PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Timer" Version="4.3.0" />
<PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.ServiceBus" Version="5.18.0" />
<PackageReference Include="Microsoft.Azure.Functions.Worker" Version="1.20.1" />
<PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Http" Version="3.1.0" />
<PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Http.AspNetCore" Version="1.2.0" />
<PackageReference Include="Microsoft.Azure.Functions.Worker.Sdk" Version="1.16.4" />
<PackageReference Include="Microsoft.ApplicationInsights.WorkerService" Version="2.21.0" />
<PackageReference Include="Microsoft.Azure.Functions.Worker.ApplicationInsights" Version="1.1.0" />
<PackageReference Include="Microsoft.Azure.WebJobs.Extensions.DurableTask" Version="2.13.2" />
<PackageReference Include="Microsoft.Extensions.DependencyInjection" Version="8.0.0" />

I’m also using Azure Functions Core Tools version:
Azure Functions Core Tools
Core Tools Version: 4.0.6821 Commit hash: N/A +c09a2033faa7ecf51b3773308283af0ca9a99f83 (64-bit)
Function Runtime Version: 4.1036.1.23224

I have libicu installed:

This issue only occurs when I try to run an Azure Function.

Let me know if you need further refinements!

Hello @Lu4nScr1pt1ng could you please refer this document https://learn.microsoft.com/en-us/dotnet/core/runtime-config/globalization

Hello @Lu4nScr1pt1ng could you please refer this document learn.microsoft.com/en-us/dotnet/core/runtime-config/globalization

The issue is that I have 'libicu' installed on my machine, but it doesn’t work out of the box. The Azure application is saying I don’t have it on my machine, even though I do.

By setting the environment variables to invariant, the build completes and the application runs, but it throws an error because my application is culture-dependent. Still, I wanted it to work normally and detect the libicu.

@Lu4nScr1pt1ng were you able to find any more info about this problem or resolve it somehow? We're running into the same problem in Ubuntu 24.04 and all the suggestions I have seen say to enable invariant mode which we also don't want.

I have not attempted this personally, but I think Docker might be a good workaround for running your Azure Function if it has issues with your current operating system. Docker's unique approach to containers can bypass OS-specific issues and maintain consistency. That being said, I completely understand the desire for things to work perfectly without any additional layers!

Thanks for the suggestion, sorry I should've been more clear. We're running into this issue with our Self-Hosted VMSS Azure DevOps agents. Funnily enough, we've actually explored containerizing our agents.

While I haven't been able to pinpoint where the exact dependency problem is, I did find this in the actions/runner-images repo.

As well as this. https://github.com/actions/runner-images/blob/0e37973a015a27a4a410a4ae37c0aa99bdd63ea8/images/ubuntu/scripts/build/install-sqlpackage.sh#L12

While this is for sql server, I did get an error about no usable libssl package found after resolving the libicu package error.

Essentially it looks like some part of the Azure Functions SDK depends on old versions of libicu as well as libssl1.1.

We resolved it by doing what they've done for libssl1.1 like this:

focal_list=/etc/apt/sources.list.d/focal-security.list
echo "deb https://archive.ubuntu.com/ubuntu/ focal-security main" | tee "${focal_list}"
apt-get update --quiet

apt-get install --no-install-recommends libssl1.1

rm "${focal_list}"
apt-get update --quiet

jammy_list=/etc/apt/sources.list.d/jammy.list
echo "deb https://archive.ubuntu.com/ubuntu/ jammy main" | tee "${jammy_list}"
apt-get update --quiet

apt-get install libicu70

rm "${jammy_list}"
apt-get update --quiet

I realize this issue is about OpenSUSE, but maybe it'll point you in the right direction and/or provide some insight to the Azure Functions team(s) to help resolve it.

@jraycroft

Thanks! In reference to your idea, I searched for the libicu70 version for OpenSUSE Tumbleweed. I found a repository that offered it, and I was able to install it and I can run Azure Functions, no problem. If anyone else wants it, here are the commands I used:

sudo zypper addrepo https://download.opensuse.org/repositories/home:cabelo:innovators/openSUSE_Tumbleweed/home:cabelo:innovators.repo  
sudo zypper install libicu70  

"Essentially it looks like some part of the Azure Functions SDK depends on old versions of libicu as well as libssl1.1." I agree

I encountered the same issue on Ubuntu 24.04 and only for building azure function project so I think that as @Lu4nScr1pt1ng supposed the azure function sdk is based on specific version of libicu and libssl (old and wrong because navigating across dotnet repo I've found that net9 supports all libicu versions currently available).
However I solved with two command (which are discouraged beacuse of compatibility and security warnings), but for anyone who are stuck on this problem and have to build asap:

wget http://archive.ubuntu.com/ubuntu/pool/main/i/icu/libicu70_70.1-2_amd64.deb
sudo dpkg -i libicu70_70.1-2_amd64.deb 

wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2.24_amd64.deb
sudo dpkg -i libssl1.1_1.1.1f-1ubuntu2.24_amd64.deb
