upgrading erlang/otp manualy due to reapearing vulnerabilities
Hi. Is it possible to upgrade Erlang/OTP manually or do we have to do it via upgrading Nprinting SR?
Currently Erlang 27.3.4.7 is used in Nprinting February 2025 SR5 but there are 4 more releases of Erlang after this version all fixing some security issue.
Customers use security scans and they are getting alerts all the times.
@dobak I would not upgrade Erlang manually. Erlang is part of the messaging service and unistalling/upgrading it manually may cause serious problems to the service as happened here.
I would contact Qlik Support and report the vulnerabilities you are concerned about. It is possible that the next version of NPrinting will come with an Erlang upgrade. Qlik Support can confirm this.

I never tried upgrading the current OTP, and I understand it will potentially break the environment, given it's tied to RabbitMQ. I know it's safe to remove older versions(leftovers) after you upgrade NPrinting.
The best approach would be to upgrade NPrinting to the latest SR and the latest release.
