Nextcloud Desktop on Linux: test and run the official AppImage cleanly

This is a reversible way to:

1. compare a failing native Nextcloud Desktop package with the official AppImage using the same existing configuration;
2. use the AppImage as the normal desktop client without creating a second configuration universe;
3. start it through a systemd user service;
4. prevent an unwanted native package from returning; and
5. switch back after a fixed native package has been verified.

Analysing Cloud-Init on a VPS with cloud-init-ctx.sh

When cloud-init behavior is confusing on a VPS, I want a repeatable way to capture the full state in one file. The helper script cloud-init-ctx.sh does exactly that.

Run it from your workstation:

./cloud-init-ctx.sh <ssh-target>
# example:

This gist is part of Nym Mixnet & dVPN: A Node Operator's Guide (2026).

Quick notes:

• The main entrypoint is docker-compose.yaml, which builds nymvpn-debian.dockerfile.
• secrets.env is an example; put your real mnemonic there and keep it private.
• The state and config live under ./config/nymvpn1/ (mapped to /etc/nym and /var/lib/nym-vpnd).

Build helpers:

• TAG_DATE=$(date +%Y%m%d) docker compose build
• TAG_DATE=$(date +%Y%m%d) docker compose build --no-cache
