I'm confirming this issue with Hardy Heron up to date.

Cheers!

confirming this happening on update. 64 - bit

OS: Xubuntu 64 Hardy Alpha 4

I also confirm this. This is might be linked to an upgrade that is associated with Update Manager + Update Manager Core.

Attaching the crash file for both

Oops adding attachment for Update Manager crash

confirming
it also prevents me from updating 3 packages
python-apt, update-manager, and update-manager-core

confirm

confirm

I also ran into this, and accidentally reported it here since it didn't come up in a search for python-apt: https://bugs.launchpad.net/ubuntu/+source/python-apt/+bug/193076

My workaround is to install the python-apt_0.7.4ubuntu4_i386.deb package from here: https://launchpad.net/ubuntu/hardy/i386/python-apt/0.7.4ubuntu4

And pin it by creating a file called /etc/apt/preferences with the following 3 lines as contents:

Package: python-apt
Pin: release v=0.7.4ubuntu4
Pin-Priority: 1000

- David

confirm this bug (Just uploaded report data).

And confirm David solution. It works.

Confirmament, x86 Ubuntu.

Methinks it has something to do with pycentral or some other dependency of python-apt, bzr, and the like.

pycentral wants libapt-pkg-libc6.6-6.so.4.5.
libapt-pkg-libc6.7-6.so.4.6 is what is provided in hardy, in the apt package.

Confirm the same bug after today's update of Hardy

Problems seem solved when trying Pitabred's workaround, except that python-apt, update-manager and update-manager-core are held back by apt.

When this bug is solved, do we need to do anything in particular to revert the installation and pin of python-apt 0.7.4ubuntu4?

Mine is bottoming out as well, wondering if it effects watching LIVE TV, Recordings, or movies... I cannot use any of them.

To revert, just delete the /etc/apt/preferences file if you created it, otherwise just remove those lines from it. You'll notice that the message "python-apt was held back" or something similar will come up now when you do an apt-get upgrade, which is because of that file.

I can also confirm it-- running latest Hardy alpha x64 in a VMWare virtual machine. Today's updates killed this and the other two packages listed above.

Confirmed on today's daily image for hardy. Pitabred's workaround makes the error go away.

It's because the preinst script in python-apt 0.7.4ubuntu5 has:

[python-package]
format = 1
python-version = python:Versions=2.4

and then /usr/bin/pycentral has @ line 1028

version_field = pkgconfig.get('python-package', 'python-version')
requested = pyversions.requested_versions_for_runtime(version_field, version_only=True)

and this ultimately calls parse_versions in /usr/share/pycentral-data/pyversions.py @ line 28,
and this expects a string of the form ">=|<=|<<|= d.d", so it breaks.

I "fixed" the issue with:

--- /root/pyversions.py 2008-02-19 01:34:19.000000000 +0000
+++ pyversions.py 2008-02-19 01:57:42.000000000 +0000
@@ -31,6 +31,7 @@
                   '>=': operator.ge, '<=': operator.le,
                   '<<': operator.lt
                   }
+ vstring = vstring.replace('python:Versions=','')
     vinfo = {}
     exact_versions = set([])
     version_range = set(supported_versions(version_only=True))

i.e. stripping off the unexpected python:Versions string.

Although what the correct fix is, I've no clue.

Confirming this with the Kubuntu 64bit python-apt_0.7.4ubuntu5_amd64.deb

Same issue here running hardy latest updates:

Confirming the bug.

From comment 32 it seems that something is wrong in the python-apt package. I hope somebody works on this & gets us a new package which fixes the issue, till then many new packages would be affected. I'm having issues with 5 packages due to this :-

 bzr python-apt update-manager update-manager-core

hi everyone:

I'm confirming this issue with Hardy up to date. this is a bit annoying right now. hope it's fixed soon.

I just got the same bug...

Confirmed. Today during update process.

This bug also turns up when using the update from gutsy to hardy. Problem is when it happens it causes a cascade of errors and causes the upgrade to die just before the cleanup and reboot stage. Then because it has broken dependencies the update manager fails to load. The terminal log of trying to upgrade the system is attached.

Trying to reload the update manager after the system upgrade:

My System is not updated from Gutsy to Hardy, my system is installed from Alpha2 and all updates, and is the same Problem!!!

I think there is a bug in the preinst script which caused the python-apt ValueError: error parsing Python-Version.

root@tiger-desktop:/tmp# diff preinst 5/preinst
8c8
< python-version = python:Versions=2.4
---
> python-version = 2.4

After I changed this line to python-version = 2.4. It works!
And you can download the deb package here: http://emblinux.org/blog/blog.asp?name=tigerz

Confirming this with the amd64 version

Sorry all, I can not upload the deb package to my blog in my office. So I post it here.

Same pb on my laptop

Confirming this bug.

Tiger:
The package attached doesn't seems to work... Gdebi reports it as corrupted.

Confirm on my system, the package it corrupted!

Alexandre and Zaeggu:

How about # dpkg -i ?

Works with dpkg -i

Could you do the same for bzr, update-manager and update-manager-core?

Thanks ;-)

sudo dpkg -i does work, but crashes of update-manager
&update-manager-core still present.

This bug was fixed in the package python-central - 0.5.50ubuntu2

---------------
python-central (0.5.50ubuntu2) hardy; urgency=low

  * fix crash in parse_versions (LP: #192992)

 -- Michael Vogt <email address hidden> Tue, 19 Feb 2008 10:03:37 +0100

I uploaded the attached change to stop it crashing. I'm not sure that this is the most elegant way to deal with it or if striping away the "python:Versions" shouldn't be done in ActionPkgPrepare.run(). I let Matthias clean that up after me :)

There is one oddity I noticed when checking the python-apt preinst:
----
if which pycentral >/dev/null 2>&1 && pycentral --help 2>/dev/null | grep -q pkgprepare
; then
        pycentral pkgprepare python-apt <<EOF
[python-package]
format = 1
python-version = python:Versions=2.4
[pycentral]
version = 0.5.50
[files]
EOF
else
        mkdir -p /var/lib/pycentral
        echo python-apt >> /var/lib/pycentral/delayed-pkgs
fi
# End automatically added section
----

It lists python 2.4 instead of 2.5 here, I wonder if there is another bug hidding somewhere.

Cheers,
 Michael

Olivier Berten & Andrey Novoselov:

I did the same modification in update-manger and update-manger-core.
Please install them using # dpkg -i too ;)

update-manager-core_1%3a0.87.8_i386.deb

That's how i fixed it (on amd64):

apt-get install python2.4
mkdir /root/pyt
mkdir /root/pyt/DEBIAN
dpkg -x python-apt_0.7.4ubuntu5_amd64.deb /root/pyt
dpkg -e python-apt_0.7.4ubuntu5_amd64.deb /root/pyt/DEBIAN

Then change this line in the file preinst:
python-version = python:Versions=2.4
to
python-version = 2.4

Then rebuild the package:
dpkg -b /root/pyt python-apt_0.7.4ubuntu5_amd64.deb

And install it:
dpkg -i python-apt_0.7.4ubuntu5_amd64.deb

Do the same with update-manager-core and you're done :)
I attach a tar with the 2 archives, but can be done easily in 5 minutes :D
Cheers

installing python2.4 solved the problem. no more errors on "aptitude safe-upgrade"/"aptitude full-upgrade" or when using dpkg :-)

I also confirme:

E: /var/cache/apt/archives/python-apt_0.7.4ubuntu5_i386.deb: subprocess pre-installation script returned error exit status 1

Installing python2.4 solves the "AttributeError: 'NoneType' object has no attribute 'byte_compile'" error messages.

the same here...

I resolved with ifoo's package:

http://launchpadlibrarian.net/12080601/packages.tar.bz2

But before i have cleaned cache (sudo apt-get clean cache)

After i've decompressed the packages.tar.bz2 in my desktop and installed the contents (with a simple double click of the mouse) in this order:

update-manager-core_1%3a0.87.8_i386.deb
update-manager_1%3a0.87.8_all.deb
python-apt_0.7.4ubuntu5_i386.deb

Initially i've a broked file (update-manager, maybe for error in sequence of installation), but with command "sudo synaptic" and with the filter "broke" i've disinstalled this error file package. After the "cleaning" i've installed the above three package of Ifoo without problems... ;)

Arghh... now i've the same problem installing "bzr"...

sudo apt-get install bzr

It seems that installing python2.4 and bzr seemed to do the trick! (see the trace above)

Now I only have jockey-common and jockey-gtk problems left. But it's another issue, isn't it (?).

i386 is doomed alright. but weirdly (and thankfully perhaps), update-manager crashed before changing the system to current broken state (on 64bit). so i'm still running kernel 2.6.24-7 and everything with it is still fine.

As a workaround installing python2.4 solves this issue.

Same thing happens for me. Strange.

My dirty Solution:
==================

Source of the bug:
The bug is produced in the packages build-time by dh_pycentral which generates a line in the preinst script like "python-version = python:Versions=2.4" instead of "python-version = 2.4".
This bug occures only when using "XB-Python-Version: ${python:Versions}" in the packages control file.

Workaround:
I attached a patch for dh_pycentral which corrects the $versions_field variable given to the autoscript method using a simple regex.

Result:
With my patch applied to /usr/bin/dh_pycentral I rebuild the packages python-apt and update-manager-core using debuild. The installation of the new generated packages works perfectly.

I take that back. Installing python2.4 didn't solve the issue for me.

This is not an appropriate place to discuss workarounds -- this is a place to identify the cause and propose proper fixes to the bug at hand. Please move nonessential discussion to another support medium,

Thanks.

I wanted to know where the appropriate place to discuss workarounds is, to move nonessential discussion to, what other (another) support medium ?

I would recommend starting a thread in ubuntuforums.org or possibly the ask
section of launchpad. The latter im not as familiar with and do not know if
they condone threads that are not direct questions.
cheers

Thanks, this worked for me.

I got also some troubles today once updating my fresh Hardy installation.

First step, I made to resolve this issue is to install Python 2.4.
It seems pycentral crashes if a packages specify a python version that is not installed.

After that I got an error when trying to update jockey-common.
This one comes from the debugging message expecting an int and it is given a string and an int.

Quick patch:

Still not working for me. Has a solution been found yet, or are people still just throwing around patches?

Nobu, did you installed python 2.4 ?

apt-get install python2.4

this will solve: " AttributeError: 'NoneType' object has no attribute 'byte_compile' "

Next, apply my patch to your pycentral.

I also got this problem, when I perform the update on the cmd
I see these messages

Setting up python-apt (0.7.4ubuntu6) ...
pycentral: byte_compile: python version '2.4' requested but not available

Setting up update-manager-core (1:0.87.9) ...
pycentral: byte_compile: python version '2.4' requested but not available

Setting up update-manager (1:0.87.9) ...
pycentral: byte_compile: python version '2.4' requested but not available

This seems fixed for me by installing the latest python-apt and python-central packages (within the last couple hours) and also installing python2.4. Perhaps a more permanent solution is still forthcoming, but so far so good. Thanks!

Installed this package and ran update-manager twice, works fine for me!

Olivier Samyn:

Thanks, I thought I had already had it installed; turns out it was 2.5 I had.
Your patch did get jockey-common installed. There's only one change made by that patch, huh?

Just installed another update for both jockey-common and python-central (among others) and,
aside from the copious locale errors, there were no problems updating the packages.

As far as recent updates (11:30PM EST Feb 19) I have no errors now.

I updated today, errors have vanished

Seems fixed in python-apt 0.7.4ubuntu6 and python-central 0.5.50ubuntu6

Confirmed for latest updates.

Thank you for taking the time to report this bug and helping to make Ubuntu better. I'm closing it because the bug has been fixed in the last version of python-central (0.5.50ubuntu7).

Cheers!

Great!
