So I noticed that the repository has moved:
I followed the instructions mentioned on this blog.
When doing apt-get update, I’m getting this error message now:
Reading package lists… Done
N: Skipping acquire of configured file ‘main/binary-i386/Packages’ as repository ‘https://packages.grafana.com/oss/deb stable InRelease’ doesn’t support archite cture ‘i386’
Grafana 5.4.2 itself is running fine on my Ubuntu 18.04 LTS (on an Intel NUC).
Why am I getting this error message?
