Create a systemd override for console-getty.service inside LXC containers to set Environment=TERM=linux (written to /etc/systemd/system/console-getty.service.d/pve-console-term.conf) instead of touching getty@tty1/serial-getty unit dirs. This targets the noVNC/LXC console behavior where console-getty.service, not getty@tty1, is used and prevents agetty cursor-position queries from corrupting the noVNC login prompt. Also remove the older workaround in create_lxc_container that forced 'cmode: console' in the LXC config, since the new override addresses the issue.
Add a forced container env (_ct_env) exporting LC_ALL/LANG=C.UTF-8 and DEBIAN_FRONTEND to ensure commands (apt, sed, locale-gen, getent, tz setup) run reliably in fresh templates that lack generated locales. Use the env when running pct exec for locale setup, timezone symlink, DNS checks, and apt installs.
Improve terminal handling: set TERM=xterm-256color only for SSH sessions by appending a guarded block to /root/.bashrc, disable /etc/profile.d/vte.{sh,csh} by renaming them to avoid CSI 6n prompt garbage on LXC/noVNC consoles, and add /etc/profile.d/00-lxc-term-size.sh to force a sane stty rows/cols when the pseudo-tty reports 0x0. These changes prevent locale-related errors and stray CSI responses in LXC containers.
Refine LXC container bootstrap and sysvinit autologin handling.
- Fix case branch formatting and change Debian-family check to an elif to avoid logic fall-through.
- Add a non-apt branch for Fedora/Rocky/Alma/CentOS/openEuler/openSUSE/Arch/Gentoo that sets the container timezone from the host and ensures curl is installed via the appropriate package manager.
- Improve sysvinit (/etc/inittab) auto-login changes: use more robust sed patterns, append a console autologin entry via heredoc, signal init to reload inittab before killing getty processes, and target getty processes more precisely to ensure proper respawn with new settings.
Replace inconsistent msg_info calls with msg_warn for mirror-list warnings and msg_custom for "Attempting mirror" lines to unify output formatting in misc/build.func and misc/install.func. Simplify tools/pve/update-lxcs-cron.sh by removing the long mirror-probing block and using a straightforward apt-get update + noninteractive dist-upgrade (and cleanup of EXTERNALLY-MANAGED) in containers to reduce complexity and improve maintainability.
Improve package mirror resiliency in misc/build.func and misc/install.func by adding fallback and detection logic for Debian/Ubuntu and Alpine CDNs. Changes include:
- Detect distro (debian vs ubuntu) and use appropriate mirror lists and primary mirror (ftp.debian.org vs archive.ubuntu.com).
- Add retry loops that try a shuffled list of regional mirrors, test connectivity, update repo files, and attempt package installs/updates again.
- For Alpine (apk) installs and updates, try alternate mirrors on failure, write /etc/apk/repositories, and surface clearer warnings/errors if all mirrors fail.
- Update interactive prompts and informational messages to reference the correct mirror list (Ubuntu vs Debian) and generalize prompt wording.
- Improve exit handling so failures are reported and abort the process when necessary.
These changes make automated installs more robust against CDN sync issues and unreachable primary mirrors.
Standardize and clarify apt mirror diagnostics in misc/build.func and misc/install.func: update warning phrasing when apt-get update fails; change per-mirror failure messages from "Mirror X: <reason>" to "Mirror X failed (<reason>)"; change success messages to "CDN set to <mirror>: tests passed"; and add informational logs like "Attempting mirror: <mirror>" when trying alternate mirrors. These changes improve visibility into mirror selection and failure reasons during package update/installation.
When apt-get update fails, capture and display the failing mirror host to aid debugging. Adds grep-based extraction of the upstream host (from /etc/apt/sources.list.d/debian.sources or /etc/apt/sources.list) with a fallback to "unknown", and includes the host in the warning/echo. Applied to misc/build.func (inside pct exec), misc/install.func (pkg_update), and tools/pve/update-lxcs-cron.sh.
Reduce noisy mirror-related output and clarify messages across misc/build.func and misc/install.func. Reword various apt/mirror status lines (hash mismatch, SSL/certificate, apt-get update failed, package install failed) and standardize success to "Using mirror"/msg_ok. Remove verbose scan/try/skip/count logs and suppression of detailed apt output to make output cleaner for automated runs. Also change the custom_mirror sed replacement to use http:// instead of https:// to support non-HTTPS local mirrors.
Add explicit detection of SSL/certificate errors when running apt-get update and treat those mirrors as failed (logs a short SSL error snippet and returns failure). Change mirror URL rewrites to use http:// instead of https:// when substituting mirror hosts, and remove ftp.in.debian.org from the AP mirror lists. Changes applied to misc/build.func (try_mirrors) and misc/install.func (pkg_update/_try_apt_mirror) to improve mirror fallback behavior and error reporting.
Reorder mirror probing in misc/build.func and misc/install.func to scan global (OTHERS) mirrors first and fall back to regional mirrors—pick up to 3 random reachable mirrors and try them. Rename related variables accordingly and keep the fallback logic intact. Update tools/pve/update-lxcs-cron.sh to define region-specific Debian mirror lists, detect container timezone to pick regional vs other mirrors, and implement a fallback loop that checks mirror connectivity, rewrites APT URIs to use a working mirror, and retries apt-get update before proceeding with dist-upgrade. These changes improve resilience against local CDN/local-regional outages by preferring globally reachable mirrors first and providing an automated mirror-switch fallback.
Make APT mirror selection more robust by scanning for reachable mirrors and retrying installs with clearer failure reasons. In misc/build.func added mirror_exit, try_mirrors and scan_reachable helpers; prefer regional mirrors (pick up to 3), fall back to ftp.debian.org, then try global mirrors. Improved detection/reporting of hash mismatches vs apt-get errors and return codes, and use a short reachability TCP check before attempting updates. In misc/install.func added a reachable-mirror scan phase, count/report reachable mirrors, and provide clearer log messages when apt-get update/install fails. These changes aim to reduce failures caused by unreachable mirrors or CDN synchronization issues.
Refactor mirror logic in misc/build.func and misc/install.func to prefer regional Debian mirrors (detected from /etc/timezone), shuffle mirror lists, and include additional AP region hosts. Add quick TCP reachability checks, limit consecutive mirror failures, and surface clearer status messages. On repeated failures, prompt interactively for a custom mirror (with validation) and handle pct exec exit codes to present more informative errors and retry behavior.
When apt-get update fails, switch from disabling hash verification/insecure repos to trying a list of alternate Debian mirrors. Updated misc/build.func to iterate a curated mirror list, rewrite /etc/apt/sources.list* to point to each mirror, and attempt apt-get update/install until one succeeds (exiting with failure if all mirrors fail). Updated misc/install.func to perform a similar mirror-rotation loop and return an error if no mirror succeeds. Also adjusted warning/error messages to reflect the new behavior. This improves resilience against repo desyncs without enabling insecure apt settings.
Replace the previous multi-step APT retry sequence (mirror swaps, sleeps, multiple retries) with a simpler fallback: on apt-get update failure disable Acquire::By-Hash, enable Acquire::AllowInsecureRepositories and attempt updates/installs using --allow-insecure-repositories/--allow-unauthenticated where needed. Restore secure settings and refresh lists afterwards, and preserve/propagate the original command exit status. Apply the same simplification in misc/build.func, misc/install.func and the Proxmox LXC cron updater (tools/pve/update-lxcs-cron.sh) to handle Debian repo desyncs more reliably and reduce complex retry logic.
Add robust retry logic for APT operations in misc/build.func and misc/install.func. Introduces an apt_retry helper and multiple fallback steps: disable by-hash, switch to a country mirror (ftp.de.debian.org), wait and retry to allow mirror sync, and as a last resort temporarily relax APT verification to allow insecure repositories to complete updates. Ensures cleanup and restores secure settings where possible, with clearer failure handling and messages to increase resilience of package installation during container builds and installs.
Improve APT retry logic to handle failures caused by by-hash/CDN issues. Both misc/build.func and misc/install.func now write an apt config to disable Acquire::By-Hash, remove /var/lib/apt/lists/* and retry apt-get update/install; if that still fails they substitute deb.debian.org with ftp.debian.org as a fallback. This makes container builds and package updates more robust against CDN/hash-related apt failures.
The missing_cmd grep pipeline in the install error handler runs
under set -o pipefail. When grep finds no match (exit 1), the
entire pipeline fails and triggers the ERR trap recursively,
crashing the recovery menu. Add || true to suppress this.
- New preflight_repo_access() warns if enterprise repos are active without subscription
- Scans /etc/apt/sources.list.d/ for enterprise.proxmox.com entries
- Tests HTTP access (detects 401/403 Unauthorized)
- Warning only — not a blocker (packages come from pve-no-subscription repo)
- Move run_preflight from build_container() into install_script() after header_info
- Shows: Header → preflight checks → 2s pause → clear (via next header_info call)
- On failure: show summary + exit cleanly (no ERR trap)
- Change all return 1 → return 0 in preflight functions (prevents ERR trap under set -Ee)
- Remove PREFLIGHT_DONE guard from build_container (no longer needed)
Introduce preflight_template_available() in misc/build.func to verify a matching OS/version template exists locally or in the online pveam catalog, and to fail early with a helpful list of available versions when none is found (exit code 225). Integrate this check into run_preflight. Also move the run_preflight invocation inside install_script to run after header_info (so preflight output is visible) and remove the earlier preflight call.
