You could inspect the pact library (

.so

file) to see what dependencies it has and if they're present on the machine. That error suggests glibc is not present (or perhaps not the correct one). Is it possible the Ubuntu version has recently changed?

hi Matt - just following up on this - we found that the issue was that in moving from

@pact_foundation/pact

version

10.0.0-beta.58

to

beta.59

(actually an auto uprev as we were using "^10.0.0-beta.58" so got the update automatically) the pact-core version moved from 13.4.1-beta.18 to 13.6.0. This in turn introduced a dependency uprev on GLIBC from 2.18 to 2.25, which caused o/s issues for existing build pipelines (in e.g. Atlassian BB).
