Had a situation where the automatic upgrade was not working, so had to manually upgrade.
From the logs it was trying to download ARM version not X64 version.
Fortunately managed to figure out the correct weblink by changing the file name slightly: https://cdn.cribl.io/dl/4.10.1/cribl-4.10.1-45136dbb-linux-x64.tgz.
Are these links listed anywhere on the cribl website, or how would we manually upgrade?
