Problems after system update

Support System Administrator
1

My productive Tryton is running locally in a VENV, still at Tryton version v7.0. Basic system is ubuntu, which I recently upgraded from v24 to v26; with this came upgrades

  • postgres 16 → 18
  • python 3.12 → 3.14

I re-created a new VENV and reinstalled all my modules. At the ‘trytond-admin’-command, this message appeared:

trytond-admin -c trytond.conf -d 70-prod --all -v

Nevertheless, the Tryton server starts without problems. The Tryton client’s launch produces this error at console:

$ tryton

nevertheless the client appears. But a login attempt results in:

but login fails with this error at client side:

As it’s my productive system, I’d be very grateful for hints on repairing this.

As this is failing when checking the password it seems a problem with passlib the library used to check password. I’m not sure which is the problem but it can be several:

  • Library is missing
  • Some of their dependencies are missing
  • You are using a hash method not compatible with the current series.

Thank you for your attention.

Well, passlib is installed in the venv.

Which would be? - I checked python modules installed against a working version - there are few more modules in my productive venv, but none missing.

I think I’m at the most recent status of python modules, ubuntu provides. Could their python modules be too outdated, so I cannot rely on those installed system wide, but have to obtain more recent ones locally? - How can I check, if that’s a likely option?

System is back at life. :smile:

Not 100% sure what was the problem, but I deleted all remaining python3.12 components from my system, and installed as many of the required python modules directly onto the system instead of into the venv.

It really feels bad when business is running - and your ERP not. (;
