The wheel bug was caused by an auditwheel issue that made the wheels incompatible with glibc 2.26. Only Linux users installing via wheels are affected; Windows, OSX, and source installs are unaffected. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why is psycopg2 2.7.3 failing on Linux with a glibc error? The Linux wheel packages for psycopg2 2.7.3 were incompatible with glibc 2.26 due to a bug in the auditwheel tool used to build them. This was fixed in psycopg2 2.7.3.1, a rebuild of the same code with corrected wheel packages. Windows, macOS, and source installations were never affected. _Developers hitting glibc wheel errors can track library patch releases like this on daily.dev._ ### What changed in psycopg2 2.7.3.1 compared to 2.7.3? Nothing in the actual code changed between psycopg2 2.7.3 and 2.7.3.1. The update only rebuilds the wheel packages to fix an incompatibility with glibc 2.26 that was traced back to bug #80 in the auditwheel packaging tool, affecting only Linux users installing via wheels. _Keep track of packaging fixes like this psycopg2 wheel rebuild through daily.dev._ --- Tags: [#python](https://daily.dev/tags/python), [#postgresql](https://daily.dev/tags/postgresql) [View this post on daily.dev](https://daily.dev/posts/postgresql-adapter-for-python-q1xf7ss5z) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"PostgreSQL adapter for Python","url":"https://daily.dev/posts/postgresql-adapter-for-python-q1xf7ss5z","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/postgresql-adapter-for-python-q1xf7ss5z"},"datePublished":"2026-08-23T12:21:33.125Z","dateModified":"2026-08-23T12:38:19.465Z","description":"Psycopg2 2.7.3.1 is a rebuild of 2.7.3 that fixes broken Linux wheel packages, with no code changes.
