Comment 1 Peter Lemenkov 2026-07-24 18:31:47 UTC
Current Erlang builds for EL9 and EL10 are available from the CentOS Messaging SIG, which tracks upstream releases and carries security backports. The current build is erlang-26.2.5.21-4, which addresses this issue.

These packages work on RHEL, CentOS Stream, AlmaLinux, Rocky Linux and other RHEL-compatible distributions:

    dnf install centos-release-messaging
    dnf install erlang

Closing here, as Erlang updates for EL9 and EL10 are delivered through the Messaging SIG. Please reopen if the SIG builds don't cover your case.
