Strange Python Errors after Upgrade to latest Beta

[Rudolph Bott]

Hi List,

I upgraded my 3.5.4 installation of NAV to the latest Beta (3.6.0b4) and
ran into the error posted below. I configured NAV from scratch, updated
the Database with the pgsql scripts and everything seems to be fine: I
can login using a LDAP backend, see the welcome page and user
information etc - but as soon as I click on 'Toolbox' I receive an error
message.

It thought it might be related to the 'ForgetSQL thing' but according to
this list, ForgetSQL is not a requirement any more (starting with 3.6) -
or am I wrong on this one?

My system is Ubuntu 9.04, running with Python 2.5.4 and 2.6.2 installed.
ForgetSQL is 0.5.1.

forgetSQL is no longer used by NAV, correct.

This is Python 2.6 complaining (this was deprecated in 2.5, but removed
entirely from 2.6, hence the error). The referenced code, however, is not
present in NAV 3.6.0b4, which leads me to think:

1. Some old, deprecated modules might be still be around in your file system.
Did you delete all the ones specified in the release notes?

2. Apache/mod_python may in part still be serving old code. Please restart
Apache after upgrading.

oops, I did a make install and did not move the old /usr/local/nav
folder out of the way. I did that now, replaced the fresh etc-folder
with the backuped-one but now I cannot start nav alltogether:

***@dkvfs033:/usr/local/nav# nav start

Nothing in the var/log folder whatsoever :(

Did that several times already :)

By "nothing", do you mean that the log files are empty, or that there are no
log files at all in /usr/local/nav/var/log/ ? Please make sure NAV processes
has the necessary write permissions in /usr/local/nav/var (as it says in the
install guide).
