Hi all,
I am looking to get some help with a failing upgrade.
Excuse my ignorance but I am very much out of my wheelhouse. I will do me best to include the relevant info on the first try.

System:

Linux HOSTNAME 5.4.0-150-generic #167~18.04.1-Ubuntu SMP Wed May 24 00:51:42 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
$ python3 --version
Python 3.8.0
$ redis-cli --version
redis-cli 4.0.9
$ sudo -u postgres psql
psql (10.23 (Ubuntu 10.23-0ubuntu0.18.04.2))

Current netbox version: 2.8.4
Desired netbox version: 2.11.12
Deployment method: Option B github

Steps taken thus far:

Review release notes and upgraded from Python3.6 to Python3.8 and configured path accordingly.
Confirmed that other dependencies are recent enough for v2.11.12.
Created new branch and pulled v2.11.12 tag
Attempted upgrade script
sudo ./upgrade.sh
sudo -H ./upgrade.sh

Output and subsequent fault:

username@hostname:/opt/netbox$ sudo -H ./upgrade.sh

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-9cytzsnf/MarkupSafe/

Troubleshooting

So as I understand it the script is creating a virtual environment to run the upgrade and unable to find the MarkupSafe pip package.
In an attempt to remedy this I have run this:

$ python3 -m pip install markupsafe
Defaulting to user installation because normal site-packages is not writeable
Requirement already satisfied: markupsafe in /usr/lib/python3/dist-packages (1.0)
DEPRECATION: distro-info 0.18ubuntu0.18.04.1 has a non-standard version number. pip 24.0 will enforce this behaviour change. A possible replacement is to upgrade to a newer version of distro-info or contact the author to suggest that they release a version with a conforming version number. Discussion can be found at https://github.com/pypa/pip/issues/12063

I am unsure if it is targeting the right environment though.

I have also reinstalled all the python3 packages as defined here: https://docs.netbox.dev/en/stable/installation/3-netbox/
I would appreciate any help in further troubleshooting this.

Thankyou.

Hi again,
So since my last post I have learnt that I probably wasn't installing markupsafe correctly and since I have targeted the venv and installed it as seen below.
Unfortunately the output from the script has not changed after this fix.

Hi again,
I have made progress!
I added MarkupSafe==0.23 to requirements.txt and the script now progresses a bit further.

Netbox doesn't pin its requirements, which means that in general installation of Netbox is not reproducible. Over time, newer versions of libraries may be released which break things (e.g. with different dependencies). The problem gets worse the older the version of Netbox you're trying to install.

Try replacing your requirements.txt with the appropriate one from https://github.com/markkuleinio/netbox-freezes (there is one which should work with Netbox 2.11.12). Presumably this is a stepping stone towards upgrading to 3.6.5, so this is only a temporary measure for you.

Regarding your permissions problems: either use sudo -E:

sudo -E pip install ...

or open a root shell with sudo before activating the virtualenv:

sudo -s
source venv/bin/activate.py
pip install ...
exit

Or use the full path to the version of pip which is already in the venv:

sudo /opt/netbox/venv/bin/pip install ...

Hello, I did have problem before, and I selected a path upgrade from 2.9.11 to 3.1.6 :

2.9.11 > 2.10 > 2.11 > 2.11.5 > 2.11.10 > 3.0.0 > 3.0.6 > 'PostgreSQL > 10' and 'Python > 3.8' > 3.0.12 > 3.1.0 > 3.1.6

You can adapt from your setup.

IMO, there are way too many unnecessary steps there. For example, it's certainly useless going 2.11.0 > 2.11.5 > 2.11.10 when you could have gone straight to 2.11.10; all the intermediate steps are just bug fixes.

I recommend: 2.9.11 > 2.11.12 > 3.6.5

For 2.11.12, use Python 3.8. For 3.6.5, Python 3.8 will still work at the moment, but 3.10 or 3.11 will give you a bit of future-proofing.

There are sometimes cases where it may help to go via intermediate releases: e.g. a new data models for Contact and ASN were added in 3.1, and the old contact/ASN fields removed from Site in 3.2, so if you want to be able to migrate your data to the new model, it helps to go via a version which has both. Therefore if you did decide to go stepwise via 3.0.x, 3.1.x etc then it's fine, but I would always choose the last patch release ("x") available on each version.

Migrating from versions earlier than 2.7.9 may be slightly more involved because of the change to virtualenv; there was also a recommended switch from supervisord to systemd a while ago. For these reasons, I'd say it's definitely best to build a fresh VM and migrate into that. However the process is the same: build and test a new 2.11.12 system, export the database (and media) from the old, import into the new, run ./upgrade.sh. Repeat to move to 3.6.5.

Emma0Z Nov 29, 2023

I totally agreed.
We made it on paranoiac problem we had when we try to upgrade to 3.1.x from 2.9.11.

As of this time, our production was stopped, and I preferred to check every step and release note (as we should all do, hehe).
So each jump were marking by “breaking change” I did a stop.

Each “big jump” we made we have to dist-upgrade (Debian version of course). For example, Python 3.8 wasn't available on Debian 10 if I remember well.

candlerb Nov 29, 2023

I'm glad it's working for you, but for a big upgrade like that which involves change of the base OS and python version, I'd recommend building a fresh VM from scratch and importing the data.

This gives you much better ability to test, and if anything is wrong you just blow it away and start again, without affecting your production system.
