python-liblarch fails to configure

[Tom Metro]

I appear to be having a problem configuring the python-liblarch (2.2.0.r157~ubuntu12.04.1) package on 12.04.1, which appears to be coming from the GTG PPA (gtg-daily).

I went to install something and saw:

The following partially installed packages will be configured:
  python-liblarch

apparently left over from a prior update. When it got to the step of configuring python-liblarch, I see:

Setting up python-liblarch (2.2.0.r157~ubuntu12.04.1) ...
SyntaxError: ('invalid syntax', ('/usr/lib/python2.7/dist-packages/liblarch/tree.py', 423, 30, " print(output, end=' ')\n"))

dpkg: error processing python-liblarch (--configure):
 subprocess installed post-installation script returned error exit status 101
No apport report written because MaxReports is reached already
                                                              dpkg: dependency problems prevent configuration of gtg:
 gtg depends on python-liblarch (>= 2.1.0); however:
  Package python-liblarch is not configured yet.

I tried following the suggestion in bug 1038466 of removing python-liblarch (that bug was actually about python-liblarch_gtk) and then reinstalling gtg, but that just triggered the same error when python-liblarch was attempted to be configured again.

Hi Tom,

liblarch was ported to python3 recently.
Apparently, ubuntu installer is using python2 to compile liblarch and this is causing the bug.
I've sent a mail to Luca Falavigna (GTG's deb package maintainer), and we're trying to patch is as soon as possible.

This bug has already been reported (Bug #1275052).

[Parin Porecha (parinporecha)]

Sorry, this bug is not a duplicate but related to Bug #1275052

[Nimit Shah (nimit-svnit)]

Hi all,
We are releasing a legacy branch of GTG for all the users who are facing configuration issues with Python3 and GTK-3.
This branch contains the code till revision 1350. Mind you, not all changes made in the daily branch will get reflected in this one. This is just for the people who are having issues for running the Python3 and GTK3 version of the code.
Here is the link to the PPA: https://launchpad.net/~parinporecha/+archive/gtg-legacy

[Parin Porecha (parinporecha)]

Hi,

I've updated liblarch dependencies and now installing liblarch via gtg-daily ppa should work fine.
Here's the link to the recipe - https://code.launchpad.net/~gtg/+recipe/liblarch-daily
and the ppa - https://code.launchpad.net/~gtg/+archive/gtg-daily

The daily build by default works for Quantal (12.10) and Saucy (13.10), and Trusty (14.04)
We've removed Precise (12.04) since the GTK version it supports (3.0) is quite old and does not work very well with the one liblarch has been ported to (3.8)

Marking this as 'Fix Released'

Tom > Thanks for reporting the bug :-)

Hi Aslam,
Latest liblarch uses python3. While you seem to be using a python2
environment.

Hi,

I've updated the debhelper rule in liblarch to python3 (sorry, I must've overlooked it).

Aslam, can you please try to install liblarch again ?

[aslam karachiwala (akwala)]

This time it installed (no error re congifuration) but still gave the syntax error:

I also tried explicitly with python3...

$ python3 /usr/share/gtg/gtg
GTG can't find liblarch and liblarch_gtk. To install missing libraries,
run the following command in the current folder:

git clone https://github.com/liblarch/liblarch ../liblarch

[Jan Pleva (jenik-pleva)]

grrrr, so sad.... I'm not able to run GTG on still supported 12.04.4 :(

[Parin Porecha (parinporecha)]

Jan > Please use the legacy GTG ppa for 12.04 (https://bugs.launchpad.net/gtg/+bug/1275642/comments/3)

I am working on solving the python-liblarch installation problem, but it will support 12.10 and newer distros

[Jan Pleva (jenik-pleva)]

@Parin that is the problem. I'm right now jumping throw supported distributions only (work usage). so it's little bit problematic for me to update to, in this case not supported, distribution. I did use legacy before, but GTG having dependency on newest package, so it want to update it and that is not what I want to.

[Jan Pleva (jenik-pleva)]

Would it be possible to add old versions for legacy, so it will be possible to force installation without update of python-liblarch?

[Jan Pleva (jenik-pleva)]

Whooo, I made it somehow, but do not know how. It looks like someone fixed this in stable repository? I found two packages compatible to each other and now it is working fine again, and even there are latest withou arguing about update, so there is no lock version needed. I did remove some of GTG repository and adding others and woala - it is working right now.

[gary mort (garyamort2)]

Either the daily package for liblarch or gtg needs to be changed.

I installed the python3-liblarch package from the daily repository. Instead of installing to /usr/lib/python3/dist-packages it installed to /usr/lib/python3.7/dist-packages - but this may have been due to an incorrect setting on my update-alternatives for python. Since I manually copied all the liblarch files from one folder to the other, I am not sure.

When trying to install gtg from daily,
apt-get install gtg=0.3.1.r70~ubuntu13.10.1

It would try to include python-liblarch with the install. Checking the dependencies with
sudo apt-cache showpkg gtg

Shows that python-liblarch is a dependency.

So either the dependency needs to be changed from python-liblarch to python3-liblarch or the python3-liblarch package must be modified so that it also declares itself as providing python-liblarch as well.

I pulled down the daily package via:
apt-get download gtg=0.3.1.r70~ubuntu13.10.1
and force installed it with
sudo dpkg -i --force gtg_0.3.1.r70~ubuntu13.10.1_all.deb

After that it seems to be working fine.

Bump...

What's up w/ this issue? I haven't been able to use GTG since this happened. I have python3/gtk3 (I'm now on Ubuntu 14.04). What do I need to do to be able to run the versions from the 'daily' repo?

Install of python3-liblarch fails if python-liblarch is present. Attempting to uninstall python-liblarch shows that gtg depends on it, which is what @garyamort2 reported as well.

[Nimit Shah (nimit-svnit)]

Hi Aslam,
Can you try this thing:
Uninstall gtg.
If python-liblarch is present, uninstall liblarch aswell.
Goto software centre and install gtg and liblarch.

GTG is not installing liblarch by default. We will figure out the solution
soon.

I know of the legacy repo. Can you explain why GTG does not run despite the
presence of python3 & gtk3? I would appreciate knowing what makes my
generally up to-date system not current enough for GTG. What are the system
requirements for running the 'daily' updates?

Pls disregard my previous msg. Gmail on my Android showed Nimit's post from 2/18 when I opened the thread and I thought it was in response to my post from earlier today.

Anyways... Here's what happened when I uninstalled gtg, autoremoved python-liblarch and then installed gtg. As you can see, python-liblarch does get installed when gtg is installed.

>I installed the python3-liblarch package from the daily repository. Instead of installing to /usr/lib/python3/dist-packages it installed to /usr/lib/python2.7/dist-package

That's the problem. Manually coping liblarch and liblarch-gtk folders from /usr/lib/python2.7/dist-package to /usr/lib/python3/dist-packages solves the problem for me.

LibLarch 3.0.1 exists now, reopen a bug upstream if you're still encountering an issue
