Upgrade metrics hosts to buster
It looks like upgrading meronense from stretch to buster would solve #30351 (moved). The reason is that there's a bug in one of the R libraries that we get from stretch-backports and that is fixed in a newer version.
Is there a reason why meronense is still on stretch? If not, can we try updating it to buster? Similarly, are there plans to upgrade the other metrics hosts from stretch to buster? Thanks!
