[Bug 2047155] Re: "Could not create socket" with apt update when update libc6 to 2.35-0ubuntu3.5 and using nscd

[Camila Camargo de Matos]

After some investigation and testing, I was able to verify that the last
jammy security update, which included, together with the actual CVE
patches, various refactoring commits, was missing some of these said
refactoring commits (some of which also included bug fixes along with
the refactoring), including one commit which was related to a bug that
was occurring in nscd. I will start working on a new  version of this
package that will include said missing commits.

** Changed in: glibc (Ubuntu)
