Hi @jalbstmeijer,

I faced the same problem today with an amzn2 linux centos rhel fedora and in order to solve it, I just followed what the error message indicates.

Process terminated. Couldn't find a valid ICU package installed on the system. Please install libicu using your package manager and try again. Alternatively you can set the configuration flag System.Globalization.Invariant to true if you want to run with no globalization support. Please see https://aka.ms/dotnet-missing-libicu for more information.

I did the .NET installation following this link, I don't think it's really necessary but try that too:

• Install dotnet

Even after installing dotnet I still got the same error.

But I managed to solve it on the spot by installing the libicu package for centOS, so you should follow these steps:

Please install libicu using your package manager and try again.

1 - You can check if libicu is installed on your operating system:

rpm -q libicu

2 - It's probably not installed so run this command to install libicu using yum:

yum install libicu -y

3 - After that check again if libicu is installed, you should see something like this:

[root@self-hosted-runner bin]# rpm -q libicu
libicu-50.2-4.amzn2.x86_64

I also followed this link to install libicu: https://yum-info.contradodigital.com/view-package/base/libicu/

I've been configuring self-hosted runners for a long time, and today was the first time I received this error, after a bit of research I was able to finish the runner configuration smoothly.

Hope this helps you too,
Regards

Hi @softlberton

Thank you very much for your feedback. I indeed got it to work after installing the libicu package.
I suppose this needs to be fixed/added to bin/installdependencies.sh?

This because projects like https://github.com/machulav/ec2-github-runner expect bin/installdependencies.sh to do it all.

Gr, J

I don't know exactly, because I ran it a few times but it wasn't enough, it seemed that my machine lacked libicu and some dotnet packages, so I didn't delve into that.

By the way, this repository is quite interesting, if possible it would be necessary to open a PR or some problem indicating the need for libicu or at least check to see if it is installed on the operating system that will be used to configure the runner.

I'm glad you were able to solve your problems, so you can close this issue, let me know.

WOW you are very fast and I appreciate that !!

I will be following closely.

Hi everyone, run.sh works fine for me but running the runner as a service with svc.sh encounters this error
libicu is installed and exported DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1
i still have the error
sudo journalctl -u 'runner-name' -f

Come to think of it... my Pull Request there probably also fixes the Amazon Linux 2 issue mentioned above.

It's interesting to see that this issue remains open and there are people working to improve this problem.

any solutions/updates?

@davi020 , not sure if it's fixed in this project. But with the 'pre-runner-script' option of the ec2-github-runner action you can now install any dependency needed.

Thanks @jalbstmeijer - I am following script based installation process based on this doc (this scripts automates the runner installation and service config setup) and I tried this on AmazonLinux3 server. The error I got was -
Libicu's dependencies is missing for Dotnet Core 6.0 Execute sudo ./bin/installdependencies.sh to install any missing Dotnet Core 6.0 dependencies.
and it got fixed by installing libicu

yum install libicu -y
