@saccadt sorry for not responding to you earlier. Ralph currently does not support python 3.7 which is the part of Ubuntu 20.04.

At this moment I would suggest you to run Ralph as a docker container using our official docket image, if it’s important for you to have Ubuntu 20.04 as a base system.

this means ralph does not natively run in ubuntu 20.04?

also debian 11 requires this package, and doesn't work :( Is there an alternative method of installing ? (no docker) ?

[martin3000]

why does ralph need libmysqlclient20 and not libmysqlclient21?

Hi @romcheg The docs still make it sound like the docker image is experimental

Is that still true? Or is it pretty safe to use now? Is there a doc that describes the full process of migrating your ralph instance off of the .deb package and onto a docker image? Thanks!

also docker-compose.yml.tmlp is not available on github

is there a workaround for this? I suspect many people attempting to install this package would prefer to use Ubuntu 20.04 rather than 18.04. Thanks!

Just installing this software, the easiest solution i found is this:

sudo add-apt-repository ppa:deadsnakes/ppa sudo apt-get update sudo apt-get install python3.6

and the installer just works like in ubuntu 18.04

This StackOverflow post was very helpful for getting past the libmysqlclient20 error.
