Comment 2 Lukas Javorsky 2022-04-07 13:18:18 UTC
We aim to rebase the zlib package in the Fedora distribution, however, due to the long list of downstream IBM patches we have to fix them as well with the help of our IBM colleagues.

Due to the complexity of this task, it may take quite a lot of time and capacity of our team.

In case of any updates, I'll provide them in this Bugzilla comment section.

Comment 4 Samael 2022-06-18 10:54:45 UTC
Is this the cause of:

Error: NodejsNpmBuilder:NpmPack - NPM Failed: npm ERR! code Z_DATA_ERROR
npm ERR! errno -3
npm ERR! zlib: invalid distance too far back
