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:

Launching a container.
Build environment is in unknown state, cleaning first.
Waiting for container to be ready
Created symlink /etc/systemd/system/dbus-org.freedesktop.network1.service → /lib/systemd/system/systemd-networkd.service.
Waiting for network to be ready...

Package udev is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  systemd

E: Unable to locate package dirmngr
E: Package 'udev' has no installation candidate
E: Unable to locate package fuse
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.

I also tried removing lxd and rebuilding my snap so that it reinstalls and reconfigures lxd but that didn't work either.

How can I solve this?

Thanks in advance.

    Timeouts usually mean your network is blocking the connections, I can confirm those IPs are visible and reachable currently from different country exfil points. Is there some type of network rules on your network that control access to the Internet directly? – Thomas Ward Nov 23 '21 at 19:41
  • so, i just checked it out. the issue seems like it. i removed ufw, ran snapcraft again. but this time, i get Waiting for network to be ready... for around two minutes, then Failed to setup networking., which fails installing udev. let me investigate it more. – Eray Erdin Nov 23 '21 at 20:11
  • Nope, this time lxc fails to set up networking as above. I ran out of options. – Eray Erdin Nov 23 '21 at 20:46
