When doing the most recent core update on one of my servers running NS8, I received an error while it was updating and the update stopped. All my other servers went through the update fine. Now, when I try to force the update via api-cli as well as when it tries to “retrieve available apps” for the dash board, I get this error:
AttributeError: module ‘semver’ has no attribute ‘Version’
Looking for a way to get past this.
Thanks
Please tell me more about the server: base os, first install date and version, previous upgrades etc.
Base OS is Rocky Linux 9.4, It’s been installed for a couple months and has been through multiple updates and had no problems to this point. All my NS8 servers are of the same version.
Please, share the full error message from a log excerpt.

Sorry took so long. Here is the trace that shows in the web interface:

When I run the python version checks, the first comes back with:
Python 3.9.18
Even though I have also installed Python3.11
runagent python3 -msemver --version gives a long list of errors

In Rocky Linux you should have both Python 3.9 and Python 3.11 installed at the same time. By default python3 points to Python 3.9, but under runagent it points to Python 3.11.
From the attached messages we see Python 3.9 is running instead. I don’t know why, but you can start from the Beta 2 upgrade instructions and try to switch the Python virtual environment from 3.9 to 3.11.
Look at the instructions here: Release notes — NS8 documentation
Thank you, I had missed that the script was needed for Rocky as well as Debian. I ran that, and it is fixed. Secondary question, I am am wondering if I then need to run the instructions for moving through the RC candidates to the final. I am not noticing any other issues at this point, but want to make sure it’s functioning as it should.
If you started with Beta 2, you need to follow all the upgrade instructions from that point onward.
As alternative, consider also to reinstall, with backup/restore of individual application instances.
