✍️ Description

Adds TeamSpeak Server, a voice/text chat server for online communities and
gaming groups — in continuous use since the early 2000s and still one of the
most widely deployed platforms of its kind.

Built primarily with AI assistance (Claude Sonnet 5, standard reasoning
effort), following AGENTS.md and .github/agents/pve-script-creator.agent.md.
Reviewed and corrected across several real install/update runs on a live
Proxmox VE 9.2.6 host — three real bugs only surfaced by actually installing
and connecting a client, not by static checks:

• fetch_and_deploy_from_url doesn't handle bzip2 (file reports
  bzip2 compressed data, which its type-detection doesn't match). TeamSpeak
  only ships .tar.bz2. Worked around with a direct curl | tar -xjf
  extraction — no other core helper covers this format, so this isn't
  reinventing an existing one.
• grep with no match exits 1, and under this project's catch_errors
  (which enables pipefail), that's treated as a fatal script error even
  though "no match yet" is the expected state while polling for the server's
  first-boot log line. Guarded every such check with || true.
• The credentials the script originally tried to capture don't exist in
  this version. Older TeamSpeak docs describe a "ServerQuery Admin Account
  created" log block with a password — current 3.13.8 never prints it on a
  fresh single-virtual-server install. Only the "ServerAdmin privilege key"
  (used once, in the client, to claim admin) actually appears. Adjusted the
  script, JSON notes and default_credentials to match observed reality
  instead of outdated documentation.

Other notable points for review:

• No GitHub release API - TeamSpeak is closed-source with no public
  source repo, distributed only from teamspeak.com. The install/update
  scripts resolve the current download URL and version by reading that page
  at run time (regex against the direct download link), since no version API
  exists. This is a real fragility trade-off, discussed and accepted over
  hardcoding a version (which would make updateable: true misleading and go
  stale immediately per this repo's own guidance against pinned versions).
• License acceptance is automated (license_accepted=1 passed to
  ts3server), the same non-interactive mechanism used by TeamSpeak's own
  official Docker image (TS3SERVER_LICENSE=accept) - confirmed against their
  published Dockerfile/entrypoint before using it.
• No arm64: confirmed by inspecting the actual downloads page - only
  linux_amd64, linux_x86, and freebsd_amd64 builds are published.
• Free tier (no license key) runs 1 virtual server with up to 32 slots - no
  account/payment needed for typical community use.

📋 Additional Information (optional)

Tested on a live Proxmox VE 9.2.6 host via the public-fork curl one-liner
(docs/guides/source-origin.md variant 1): fresh install, service/port
verification (9987/udp, 10011/tcp, 30033/tcp), a forced update run (old
version marker, real re-download, restart), and confirmed the virtual
server's database/config survive an update (no new privilege key generated
on the update restart, meaning existing data wasn't wiped).

600+ stars: TeamSpeak Server has no public source repository (closed-source),
so there's no GitHub star count to check - noting this explicitly rather than
leaving the box ambiguous. Judging by real-world adoption instead: it's one
of the most widely deployed voice platforms in gaming, in continuous use for
over two decades.

📦 Application Requirements (for new scripts)

⚠️ Do not remove this section.
It is used by automated PR validation checks.
If this PR is not a new script submission, leave the checkboxes unchecked.

Required for 🆕 New script submissions.
Pull requests that do not meet these requirements may be closed without review.

• The application is at least 6 months old
• The application is actively maintained
• The application has 600+ GitHub stars
• Official release tarballs are published
• I understand that not all scripts will be accepted due to various reasons and criteria by the community-scripts ORG

🌐 Source

• Website / downloads: https://www.teamspeak.com/en/downloads/
• TeamSpeak 6 (beta) note: they do publish a real GitHub repo for the
  next-gen server (github.com/teamspeak/teamspeak6-server) with proper
  releases, but its server licensing is still marked "Coming Soon" on their
  own site - deliberately not building on that yet.

[github-actions]

Try this script

COMMUNITY_SCRIPTS_URL=https://raw.githubusercontent.com/opastorello/ProxmoxVED/add-teamspeak \
bash -c "$(curl -fsSL https://raw.githubusercontent.com/opastorello/ProxmoxVED/add-teamspeak/ct/teamspeak.sh)"

COMMUNITY_SCRIPTS_URL is not optional. Fetching the ct/ script from a branch
does not tell the engine where that branch is — with bash -c "$(curl …)" there
is no file on disk for the scripts root to be derived from, so it would fall back
to upstream main and look for the install script there.

Against a core branch as well

Add COMMUNITY_SCRIPTS_CORE_URL=https://raw.githubusercontent.com/OWNER/core/BRANCH
to test an engine change at the same time. The two resolve independently.

Useful flags while testing

dev_mode=net logs every fetch with status and duration, so you can confirm the
branch is really being used. dev_mode=keep stops a failed build from deleting
the container along with the evidence.

Closing: this duplicates an already-merged script. TeamSpeak exists in production as ct/teamspeak-server.sh / install/teamspeak-server-install.sh (by @tremor021, merged mid-2025) — the discussion (#4040) was already closed as RESOLVED with a 'Merged into main' comment, which I missed before starting. My duplicate check only looked for the exact slug teamspeak, not the actual slug used (teamspeak-server). Apologies for the noise.
