ubuntu 12.04 dependencies

deepspace · Post by **deepspace** » Wed Jul 13, 2016 3:01 pm

Hello
trying to install the last version of picoscope software on my ubuntu 12.04 (I have a picoscope 2206) I have the following messages:

Code: Select all

deepspace@Hal9000:~$ sudo apt-get install picoscope

 picomono : Depends: libcairo2 (>= 1.12.0) but 1.10.2-6.1ubuntu3 is to be installed

as far as I understand the problem is related to libcairo2 that on ubuntu 12.04 is 1.10.2-6 instead of >=1.12.0 as required.
Some suggestions?
thanks a lot
gianni.

Have you run

sudo apt-get update

before

sudo apt-get install picoscope

yes!
anyway I repeat the update and the result is exactly the same

I have same problem with two computers running both Ubuntu 12.04 and before last release one of those was running fine (trying to install on the second one I discover the problem)

do you think it is possible to install the old release (the one running fine is the 6.11.8.10)?

or at least a release that supports libcairo 1.10.2-6.1ubuntu3?

thanks a lot
ciao

Looks like permission issue? Things to check:
* Is you user member of group pico ? Run `groups` command to verify this.
* Is device having correct permissions set up? Run /opt/picoscope/share/doc/libps2000a/usbtest script to verify
* Is udev config present and active? Check for /etc/udev/rules.d/95-pico.rules file

Maybe reboot is all you need. You can also try to reapply the permissions

Code: Select all

sudo dpkg-reconfigure libps2000a

or apply them manually to your user.

If it not permissions, edit /opt/picoscope/bin/picoscope and replace anything after PicoScope.GTK.exe with double quotes and run it in the console to receive more verbose information about the crash.

Hi Mario
yes I'm in pico group

Code: Select all

$ groups
deepspace adm dialout cdrom sudo audio dip plugdev lpadmin sambashare pico

usbtest gives the following results:

Code: Select all

$ /opt/picoscope/share/doc/libps2000a/usbtest

****************************************************************************
*                  Pico Technology Linux USB Diagnostics                   *
****************************************************************************

This script looks for Pico USB devices connected to your computer
and checks whether you are able to access them. If your user account
does not have permission to access the devices, the script will try
to suggest how to correct this for your particular Linux installation.

Press enter to continue...

Getting user and group information...
 - You are running this script as deepspace.
 - You are in the following groups:
     deepspace adm dialout cdrom sudo audio dip plugdev lpadmin sambashare pico

Please connect your Pico USB device and press enter to continue...

Pico USB device found: /dev/bus/usb/003/002

 - It belongs to root (which is not you) who has permissions rw-
 - The members of group pico (which you are in) have permissions rw-
 - Everyone else has permissions r--
 - You can write to this device and so will be able to use it.

95-pico.rules contains the following:

Code: Select all

$ more /etc/udev/rules.d/95-pico.rules
ATTRS{idVendor}=="0ce9", MODE="664", GROUP="pico"

I've done a reboot too but when I start picoscope (after the editing you suggested in the /opt/picoscope/bin/picoscope script ) I ear the relay clicking on the picoscope hardware but it is still crashing (or some times hang with a blank picoscope window).
The output of the script is the following: (sorry it is a bit long....)

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

hope this helps

Looking at the stack, it seems that you have some sort of unsupported settings in the signal generator.
Does picoscope work ok, when using only demo device? You can then reset default startup settings.
Alternatively you could look into your home folder for .local/share and rename or move Pico Technology folder to see if it helps.

I reset the default settings and also loaded factory settings
also done renaming of the .local/share/Pico Technology directory without success....

sometimes, as I said in a preceding post, the program get stuck with a blank window, no way to exit or do something, I have to kill mono process to exit; other times it crashes..

I've also connected the scope to a different usb port, usb2.0 instead of usb3.0 again without success

one more thing: after relais clicking the red led on the picoscope switch off while normally, as I remember, it stay lit

Gianni

Hi Gianni,

If demo mode works, the the software side is more likely to be OK. I run several tests with your scope model and didn't run into any problems. How about going into demo, waiting for it to start, the plugin the device and try open it via File -> Connect device?
Did you try the scope on different system, preferably running Windows with PicoScope 6 on it? It is also possible that your USB port / hub /cable are damaged, as after clicking the relays device starts to draw more current, which may cease the communication.

Mario
first of all thank you for all your suggestions.
following are my answers:
I started in demo mode and then connected device.... result: crash
I suspect that the key is in the last line of the syslog attached "mono did not claim interface 0 before use"

Code: Select all

Anyway.... I'm using the scope on my laptop(Matrix) (Ubuntu 12.04)
and this is the "about Picoscope 6 beta" info I have on the running system

Code: Select all

PicoScope 6 - PC Oscilloscope software version: 6.11.8.10
Copyright  1995-2015, Pico Technology Ltd

Model: PicoScope 2206
Serial Number: AX768/330
USB Version: 2.0
Calibration Date: Thursday, February 16, 2012
Hardware Version: 1
Driver Version: PS2000A Linux Driver, 1.1.5.28
Firmware Version: 1.3.3.0 / 0.5.7.0

syslog in the laptop (Matrix) does not have same messages as the system not working (the desktop Hal9000)

Code: Select all

Aug  2 22:07:27 Matrix kernel: [ 1626.730761] usb 2-1.3: new high-speed USB device number 6 using ehci-pci

Aug  2 22:07:27 Matrix kernel: [ 1627.034653] usb 2-1.3: reset high-speed USB device number 6 using ehci-pci

in fact, starting from last software release of picoscope 6, I have the message: "Not all updates can be installed"
from update manager of the laptop (I assume it is the picomono/libcairo2 dependencies you already solved) but I prefer not doing any update

also when I bought picoscope (January 2014) I installed the software on the desktop and it was running: it is connected to a USB hub with external power supply (2.5Amps)

definitely I think I should upgrade my system to ubuntu 14.04 or 16.04 but I'm now in the middle of an important project and I prefer remain in 12.04.

For the moment I use the scope on the desktop through the laptop via network and it works fine, only a little slow....

thanks again
ciao
