I have installed octave on Ubuntu 16.04 originally without the ppa (version 4.0.0), but the problem remains with the ppa (version 4.0.2).
To install it, I have runned : sudo apt install octave octave-sockets and it went fine.
But when I am in octave-cli and I run this command: pkg load sockets. I have the following error:
error: __which__: /usr/lib/x86_64-linux-gnu/octave/packages/sockets-1.2.0/x86_64-pc-linux-gnu-api-v50+/socket.oct: failed to load: /usr/lib/x86_64-linux-gnu/octave/packages/sockets-1.2.0/x86_64-pc-linux-gnu-api-v50+/socket.oct: undefined symbol: _ZNK5ArrayISsE17resize_fill_valueEv

load_packages at line 60 column 3

So I am supposing that the package octave-sockets is missing a dependency but I don't find which one. If you can help me with that... Thank you very much!
Rather than using Ubuntu's packaged octave-sockets package, you're likely to have a better experience if you install the package directly from Octave instead
pkg install -forge sockets

On Net::SSH2::Simple,
It has been no longer connected by ssh after update Windows7 to Windows10.
With following error.

My code are

$ssh2->connect( 'xxxx.com', 22 ) ;
$ssh2->auth_password( 'username', 'passwd' );

But
This code works fine by using Net::SSH2.
Only Net::SSH2::Simple doesn't work.
To xxxx.com connection is fine. and no username,password mistakes found.
How can I fix that.

Net::SSH2::Simple 0.01 was released Dec 13 2009. At that time Net::SSH2 was at 0.28 (2009-10-24), it is now at 0.70 (2019-3-17).
I got Net::SSH2::Simple to work on Windows10 64bit / Strawberry Perl 5.30.0.1 (64bit) by installing the earlier version 0.58 (2015-12-20) of Net::SSH2 using
cpan install SALVA/Net-SSH2-0.58.tar.gz
Version 0.59_20 (2016-05-11) gives the 'net_ss_timeout: invalid object' error . The change log for version 0.59_01 has this warning
** WARNING: this release includes lots of changes, some
visible, most internal. Regressions are expected. Also,
it introduces some minor backward incompatible changes -
but in those cases, the old behavior was broken or insane
anyway.
I need to read a file myFile.bmp in Octave but it doesn't work.
I have:
Ubuntu 15.04

If you installed everything from the Ubuntu repositories, then you are probably affected by an Ubuntu packaging issue. It was described in comment #6 of Ubuntu bug #1372202.
Since Ubuntu 15.04 has already reached end of life, they probably won't fix it. You can:
upgrade Ubuntu
build Octave from source yourself
I am using Enthought's Canopy environment on a 64 bit Linux OS. Everything works fine in the Ipython console which is attached with the editor. But when I ipython in the terminal and try to use magic functions, I get the following error.

So, I installed a bare bones iPython shell which is not the one provided by Canopy and tried the same magic functions in there and it works fine.
Have I done something wrong with the installation? Please help
Thanks a lot

This is not a solution, but just an observation. My desktop is MacOS-X and I connect to a Centos machine to run Enthought Canopy both 64 bit. I get the same error message as OP if I ssh from iterm2, but not if I use the Terminal app.
I am not sure what the underlying reason is, but may be someone can verify if a similar situation is true for linux. Interestingly I can use either iterm2 or Terminal on the local canopy without any issues.
Update:
I just noticed that the TERM environment variable in iterm2 was set to "xterm" while the Terminal app was showing "xterm-256color". Issuing the command export TERM="xterm-256color" before running the Canopy ipython in terminal solves the issue for me in iterm2.
Problem reproduction:
$ python -c 'import curses; curses.setupterm()'
Traceback (most recent call last):
File "<string>", line 1, in <module>
_curses.error: setupterm: could not find terminfo database
This irc log gave me the idea that this error was to do with libncursesw.
My Canopy version is 1.0.3.1262.rh5-x86_64. I have installed it to ~/src/canopy.
In ~/src/canopy/appdata/canopy-1.0.3.1262.rh5-x86_64/lib we can see that my canopy install has libncursesw.so.5.7.
My machine (Debian Wheezy 64bit) has libncursesw.so.5.9 (in /lib/x86_64-linux-gnu/libncursesw.so.5.9). I made canopy use this. You can toggle the problem on / off by using LD_PRELOAD and pointing at the .so file.
Solution
Replace libncurses.so.5.7 with libncurses.so.5.9:
CANOPYDIR=$HOME/src/canopy
CANOPYLIBS=$CANOPYDIR/appdata/canopy-1.0.3.1262.rh5-x86_64/lib/
SYSTEMLIBS=/lib/x86_64-linux-gnu
cp $SYSTEMLIBS/libncurses.so.5.9 $CANOPYLIBS
ln -sf $CANOPYLIBS/libncurses.so.5.9 $CANOPYLIBS/libncurses.so.5
It appears that Canopy User Python is not your default. See this article:

Update: Not true here -- instead, see batu's workaround answer.
I'm brand new to Python programming and trying to get myself a functional base from which I can run things like the IPython Notebook which looks pretty exciting.
Thus far I have both Python 2.7 and 3.3 from python.org installed in OS X 10.6 (Snow Leopard) as well as ActiveTcl 8.5.13. Almost everything that I've tried thus far works as expected. I'm focused on learning 3.3, but want to have the option of using 2.7 too. I read up in several documents that I need to start gaining access to PyPI packages using a Python package manager and that distribute is the one I should use for 3k. So I installed that according to the documentation I found and it seemed to work fine.
I also installed pip as directed, and a number of others.
At this point, I have:
$ pip freeze
distribute==0.6.34
ipython==0.13.1
nose==1.2.1 (installed after IPython)
pexpect==2.4 (installed after IPython)
pyflakes3k==0.4.3
readline==6.2.4.1 (installed after IPython)
At this point, I'm doing this from ipython.org guidance
And when I did $ easy_install pexpect, I got a bunch of errors:

That looks bad to me (although I don't yet have the expertise to really interpret it), and so I'm not sure if I have a complete install of pexpect.
After installing nose (before pexpect as per URL above), I tried running iptest and iptest3 from the command line, and both failed to find the command, but after I did easy_install ipython again (after nose), I noticed that this install added iptest3 (as well as ipcluster3 and a few other scripts) to my path, and now my bash shell can find iptest3, but when I run it, I get some more bad-looking output:
$ iptest3

After doing all that, I noted that my /Library/Frameworks/Python.framework/Versions/Current had been pointing to 2.7, and I guessed that that might be related to my problems and changed the symbolic link to point to 3.3, but iptest3 still fails with the error above.
Any other thoughts on what to do to fix this? It's clear that iptest is pretty important to doing anything else (like IPython Notebook) I want to do.
There is a py3-compatible fork of pexpect called pexpect-u (the u is for unicode, the main difference between the two). You need this to run the pexpect-based parts of IPython on Python 3.
Should be a simple
pip install pexpect-u
side note: pexpect-u is by IPython developer Thomas Kluyver, who did most of the heavy lifting bringing py3 compatibility to IPython.
