Installation issues

dolfinx
1

Hello everybody,

I like to install htop, vi, and other things within a dolfinx-container at a fresh ubuntu 20.04. Unfortunately, “apt update” doesn’t work. The output

Failed to fetch http://archive.ubuntu.com/ubuntu/dists/impish/InRelease Could not connect to archive.ubuntu.com:80 (91.189.88.152). - connect (111: Connection refused) Could not connect to archive.ubuntu.com:80 (91.189.88.142). - connect (111: Connection refused)

is (probably) caused by the missing proxy configuration for apt.
Specifying a proxy for “apt” in turn is failed by missing a command-line editor within the container. Have anybody an idea?

Thanks a lot,
Mario

Are you saying that you are using a dolfinx docker container, and that you cannot run the command
apt update in the container?

If so, I cannot reproduce this issue on my ubuntu 20.04:

docker pull dolfinx/dolfinx

Following your instructions, I still got the same result. I defined proxy in

/etc/systemd/system/docker.service.d/http-proxy.conf

and in

.docker/config.json

Do I miss something?

I would suggest having a look at:

I would also suggest you try to use apt update on an even slimmer image to make sure that your setup works, such as ubuntu impish: Docker Hub

Great, the link you provided contains the solution. Just an idea, pre-installation of ‘vim’ or ‘nano’ in upcoming images would be helpful.
