Timeout while Connecting archive.ubuntu.com and security.ubuntu.com

snapcraft
1

I have a snapcraft.yaml as below:

name: tgcli
version: git
summary: A Telegram Terminal Application
description: |
  `tgcli` is a terminal application to send
  message with bots on Telegram.

base: core18
confinement: devmode

parts:
  tgcli:
    plugin: rust
    source: .

apps:
  tgcli:
    command: bin/tgcli

I’m trying to build a Rust terminal application. I am here in the documentation. I run snapcraft. It tries to connect archive.ubuntu.com and security.ubuntu.com, yet fails to do so after a couple of minutes. The full output is:

Package udev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or

An error occurred when trying to execute 'apt-get install dirmngr udev fuse --yes' with 'LXD': returned exit code 100.

I have tried to solve it, I have seen solutions like in this one, yet it does not work. I think it’s because snaps work in a confined environment.

How can I solve this?

Thanks in advance.

There haven’t been any anwers for days. Seems like I ran into some niche problem.

So, I’ve had this problem since I switched to wireless network. I had been using cabled network before.

Since I switched to wireless network with my wireless adapter, I haven’t been able to use KDEConnect either. This made me suspect of some firewall of some sort.

I changed “Firewall Zone” in “Network > Connections” from empty value to trusted.

Firewall Zone Option
Firewall Zone Option873×665 33.2 KB

KDEConnect has been working since then. However, I still have problem pinging 2001:67c:1360:8001::23.

Changing “Firewall Zone” to home also does not work. It also blocks KDEConnect and that IP is not still reachable.

Does multipass work?

Do you have network in a default 18.04 LXD environment? (e.g.; lxc launch ubuntu:18.04)

Multipass didn’t have it either.

However, a couple of days ago, I bought a new HDD and totally wiped my disk structure to install KDE Neon. So, things have changed.

I have no problem after formatting. It was something about my machine I think.
