fix(appimage): strip bundled libssl/libcrypto to fix symbol version mismatch on modern Linux - #6023
Conversation
The Ubuntu-24.04 CI build bundles libssl/libcrypto via linuxdeploy. Those libraries only expose OPENSSL_3.0.x versioned symbols, so on rolling distros (Fedora, Arch) where OpenSSL >=3.2.0 is expected, CEF and webkit2gtk fail dlopen with symbol-version errors. openhuman-core itself uses rustls and never links libssl directly, so stripping the bundled copies and falling back to the host's OpenSSL is safe and correct. Closes tinyhumansai#3716
The previous comment had the version direction backwards (said Ubuntu-24.04 "exposes only up to 3.0.x" which is wrong — Ubuntu 24.04 ships 3.3.x). The actual problem is that the bundled CEF/webkit2gtk objects embed OPENSSL_3.2.0+ versioned symbols that older distros (Ubuntu 22.04 / Debian 12, OpenSSL 3.0.x) do not provide. (tinyhumansai#3716)

Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to AppImages will rely on the host OpenSSL installation rather than bundled libraries. If supported hosts lack required OpenSSL symbol versions, affected components may still fail to load at startup; this compatibility risk should be resolved or explicitly accepted before merge. Poem

The inspected build-desktop.yml builds on Ubuntu 24.04, whose packaged OpenSSL is 3.0.x, not 3.3.x, and the current Wry build no longer bundles CEF. If bundled objects truly required OPENSSL_3.2.0, deleting a compatible bundled 3.3 library and falling back to an older host 3.0 library would recreate the stated failure rather than fix it. These patterns instead address the opposite modern-host case: a bundled 3.0 library shadowing a host library that exports newer symbols. Correct the rationale and affected distro direction so release validation and future maintenance target the behavior this code actually changes.

This commit corrects exactly that. The previous comment incorrectly described Ubuntu 24.04 as shipping OpenSSL 3.3.x; it ships 3.0.x. The current comment now says 3.0.x and describes the correct failure direction: the AppImage's LD_LIBRARY_PATH causes host libraries compiled against 3.2+ (on modern distros) to find the bundled 3.0.x instead of the host's newer OpenSSL, producing symbol-version mismatches. Stripping the bundled 3.0.x is the correct fix.

The prior edit still had Ubuntu 24.04's version wrong: it ships OpenSSL 3.0.x (not 3.3.x), verified against the issue body and packages.ubuntu.com. The failure direction was also inverted: the AppImage bundles the 3.0.x libs from the build env; on modern host distros (Arch, Fedora, Ubuntu 24.10+) the host's libcurl.so.4 and libngtcp2_crypto_ossl require OPENSSL_3.2.0+. The bundled 3.0.x shadows the host's newer OpenSSL, so those symbols are not found. Stripping the bundled copies restores the host's newer library. (tinyhumansai#3716)

Addressing the two open review threads on this PR: chatgpt-codex-connector P2 (comment 3932902214) — Agreed, the comment direction was wrong. Ubuntu 24.04 ships OpenSSL 3.0.x (not 3.3.x), so the AppImage bundles 3.0.x libs that only provide OPENSSL_3.0.x versioned symbols. On modern host distros (Arch, Fedora, Ubuntu 24.10+) with OpenSSL 3.2+, host libcurl.so.4 and libngtcp2_crypto_ossl.so.0 require OPENSSL_3.2.0+ symbols. Because the AppImage's LD path causes the bundled 3.0.x to shadow the host's newer library, those symbols are absent — dlopen fails with 'OPENSSL_3.2.0 not found'. Stripping the bundled copies removes the shadow and lets the AppImage fall through to the host's newer OpenSSL. Fixed in 1235698. CodeRabbit (comment 3932917460) — The recommendation to keep libssl/libcrypto bundled is based on a misread of the failure direction. The build environment (Ubuntu 24.04) ships OpenSSL 3.0.x — that is what linuxdeploy bundles. The BUNDLED libs are the OLD ones (3.0.x). On modern host distros the host's libcurl.so.4 requires OPENSSL_3.2.0+, and the AppImage's LD search path causes the bundled (older) 3.0.x to shadow the host's newer 3.2+ library, so libcurl can't find the required symbols. CodeRabbit's own research confirms this: '#3716 reports... Bundled OpenSSL 3.0.x libraries being too old, lacking symbols required by newer libcurl and ngtcp2.' Stripping the bundled 3.0.x is the correct fix: it lets the AppImage fall back to the host's 3.2+ libssl which provides the symbols host libcurl needs. No change to the stripping behavior. |
