Mozilla Firefox APT special

The Mozilla Firefox APT repository is incompatible with legacy apt-mirror. Here’s how I install apt-mirror2 as a dedicated python-virtualenv

# apt-get install virtualenv
# virtualenv --no-setuptools /usr/local/apt-mirror2/
# /usr/local/apt-mirror2/bin/pip3 install -U apt-mirror
# /usr/local/apt-mirror2/bin/apt-mirror --help
  • Repeat as-is to update.
  • Here’s the bug that neccessitates the --no-setuptools option: “ModuleNotFoundError: No module named ‘debian'”

mirror.list entry for the Mozilla Firefox APT repository:

deb-all [signed-by=/path/to/packages-mozilla-org.gpg] https://packages.mozilla.org/apt mozilla main
deb-amd64 [signed-by=/path/to/packages-mozilla-org.gpg] https://packages.mozilla.org/apt mozilla main

How to convert Mozilla’s sloppy ASCII-armored PGP key:

$ curl -s -O https://packages.mozilla.org/apt/repo-signing-key.gpg
$ file repo-signing-key.gpg
repo-signing-key.gpg: PGP public key block Secret-Key
$ mv repo-signing-key.gpg repo-signing-key
$ gpg --dearmor repo-signing-key
$ file repo-signing-key.gpg
repo-signing-key.gpg: OpenPGP Public Key Version 4, Created Tue May 4 21:08:03 2021, RSA (Encrypt or Sign, 2048 bits); User ID; Signature; OpenPGP Certificate

urlwatch for new daily Ubuntu Server ISO

Somewhat desparate because at the time of starting this post, the (pre-beta, non-LTS, not blaming anyone) server image in question was badly broken.

name: Ubuntu Server Daily ISO
url: https://cdimage.ubuntu.com/ubuntu-server/daily-live/current/SHA256SUMS
filter:
  - grep: .*-live-server-amd64.iso

systemd-run ephemeral timers as replacement for at

Goes great with “hardened” systems that deny use of at(1).

Run a command 60 seconds from now, via the user’s private systemd (after logout only if session lingering is enabled).

systemd-run --user --on-active=60s -- logger --tag foo "Hello world"

Run a command 2 minutes from now, privileged or as a specific user via the global systemd:

sudo systemd-run --uid="${LOGNAME}" --on-active=2m -- touch /tmp/hello

Insights

systemctl --user list-timers
journalctl --user -u 'run-*.timer'
sudo systemctl list-timers
sudo journalctl -u 'run-*.timer'

Mozillateam Firefox on Debian

$ sudo tee /etc/apt/sources.list.d/mozillateam-ppa.list <<Here

systemd service: ExecStartPre as root

[Service]
