Cannot install senrty on-premise on ubuntu 18.04

Hi
i’m trying to install sentry on ubuntu 18.04 with official docker installer

---:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.4 LTS
Release:        18.04
Codename:       bionic

---:~$ docker --version
Docker version 19.03.12, build 48a66213fe

---:~$ docker-compose --version
docker-compose version 1.26.2, build eefe0d31

there is some issues with debian repositories, which prevents successful installation

sudo docker-compose build post-process-forwarder worker web cron sentry-cleanup ingest-consumer symbolicator-cleanup snuba-cleanup

i have to use a proxy server which i configured according this:

Install log:

The logs suggest that you have a configuration issue somewhere. Maybe this topic would help you: Setup Sentry on premise on a server with http proxy

not helping at all, by sending what i sent in the question.

cannot install after version 10.0 , tried many things

Cleaning up...

i have installed version 10.0 in a same way and there was no problem, there is a problem in the installer

I referred to the whole discussion, not just to the Medium post (I did see it was the same link).

I don’t think we have changed anything that would affect this. Here are all the changes since v10: https://github.com/getsentry/onpremise/compare/10.0.0...20.7.2#diff-3fbb47e318cd8802bd325e7da9aaabe8
