you will need to either update the glibc library on your system to a version that is compatible with Grafana, or downgrade Grafana to a version that is compatible with the version of glibc you have installed.
Updating the glibc library on your system may require compiling the library from source. If you are not familiar with how to do this, or if you do not want to go through the process of compiling and installing the library from source, you may want to consider downgrading Grafana to a version that is compatible with the version of glibc you have installed.
