I am trying to install Cygwin on someone's computer. During the setup, when
the window with the websites to get cygwin from shows up, it's empty. I tried
typing some links, that I know work (tried it on another machine) and they don't work - getting an error message. (something about not being to get the .ini ... )
Any ideas?
If the list of websites isn't being populated, Setup.exe is unable to get to the internet. Make sure you are connected (including checking your Proxy settings) and try again.

Let me give a quick background of the work I do and then I'll explain the problem I am facing.
I am a software developer with more than 15+ years work experience. My work involves a lot of varied tasks:
data analysis using R, Python
development of web applications using Ruby on Rails, JS, etc.
building models using open source libraries
So far, I have been doing all this in my personal laptop (Ubuntu 18.04) and have faced no issues.
But I would soon need to start using a laptop provided by the organisation that I am working for. This org is not a IT company, it's a public body. They only use Windows (10) and don't provide admin access to anyone. It's very hard to get permission to install any kind of "approved" software. Just to give an example, they refused to install Chrome in my laptop as they wouldn't be able to control the updates.
So here's my problem - what do I do to work peacefully using their laptop? The primary reason I have to use the work laptop is that there are a lot of important documents kept in shared drives that are accessible only in their machines.
I have been looking at options like WSL or Hyper-V. But, before I put in a request to the IT team to get them to agree, I wanted to know a few things:
1) Which among WSL or Hyper-V would be the better approach for setting up the dev environment that I want?
2) IF I get the IT team to install WSL/HV, would I be able to set up everything else without having to go back to them for each software? Is there a way of secure local admin access these options would provide that will ease their concerns?
3) Is there some other way of setting up what I want?
If still applicable and actual I can share my solution:
If you should work on a windows machine where you don’t have administrative privileges, you can very easily make a portable R/Rstudio installation.
Download a recent version of R from the CRAN site and the recent version of RStudio. After download extract RStudio installation exec with 7Zip and copy files from $_OUTDIR to the desired location (in case you making an update, simply overwrite all files, that already exist). Your RStudio executable will be in
your-chosen-directory/bin/rstudio.exe
Then run CRAN-R installation, ignore the warning that you don’t have administrative privileges and go forward until installation will complete. Run RStudio, from the menu
Tools->Global Options
locate where your R installation is located.
If you performing an update (more recent version of R), copy all files from the library subfolder of the old R installation into new, but this time DON’T OVERWRITE! This operation vill preserves the packages you have installed in the previous version of R. After copying update all your packages from the RStudio window (Packages->Update). When the packages update process will end check which packages failed to update (You will see warning messages near them in the RStudio console). Remove these packages (write down names of failed packages and delete corresponding folders from library subfolder). For this, you will need to exit from RStudio. After deletion launch RStudio again and execute the packages install command in the RStudio console:
install.packages(c("package1", "package2", "package3"))
Congratulations, You are ready to go!
I want to connect to my webserver, but the ssh is disabled, so decided to try using the webdisk service the server-provider suggested. My Nautilus though can't seem to be able to connect the davs server.
When I run it and ask to join it recognizes the davs address but when I press the "connect" button, it shows me an error saying: "unhandled error: cannot connect to destination (...)".
Whenever I try doing this as superuser though it doesn't even let me click on the connect button saying: "This file server type is not recognized."
I thought it might be due to some packages missing to handle davs connections. Can it be the problem? I'm using Nautilus 3.10.1 on Deepin Linux (which uses the ubuntu repositories). Can anyone tell me what packages do I need to install, or how do I get this working?
I'm quite sure you've found the answer yourself since Jan 2016, but for the sake of others who may search for the answer, I'll say it:
Make sure you have davfs2 package installed.
I would like to send my Python3 script to my father-in-law and grandmother. Each has their own Windows machine, one is running Windows 7 and the other is running XP.
Not sure how to package it up for them to run on their respective machines. Is there such a method?
My script prompts, while in the IDE environment, for Keyword, path, filename. So there are some inputs, the user has to type in. Not sure if that will affect the portable script creation.
After reading through some responses here on StackOverFlow, I found py2exe does not work with Python 3.
Also Pytonw, suggested here as well, looks very complicated. I don't think either of my relative could carry out those steps.
Lastly CX-Freeze site I get ublock filters-Badware risks and a big warning window when I visit their website.
I've used cx-freeze to deploy python apps compiled to windows .exe files for us by computer novice users for several years and it has worked well. you will occasionally run into issues with dependencies you will have to take extra steps for (Datetime for example) but nothing that isn't surmountable. The easiest way to handle it is to install the folder on the computer yourself and create a desktop shortcut to it for the user. That keeps it simple for them. If you are not close to them you can always use a program like team viewer to gain access to their computer like remote desktop.
I am working my way through 'The linux command line' (http://linuxcommand.org/tlcl.php) . Since I don't have a local linux environment and I have to work in windows , I am telnetting into an Ubuntu 14.4 LTS instance on EC2 , with putty. On page 114 , when I run the xlogo command I get:
ubuntu#ip-172-31-22-65:~$ xlogo
Error: Can't open display:
How can I get this working?
xlogo will try to access the current Xserver to display a logo. If you're telneting to a box, you will not have an X server available, which is what that "can't open display" message is saying. It's trying to look at your DISPLAY environment variable to use that to show the logo on, but you don't have a display to use, and thus have nothing in your DISPLAY variable.
You will need access to an X server somewhere to do that step. One option would be to install cygwin on your Windows machine. Then you wouldn't need the remote linux box for most steps I imagine, because you could just use your local cygwin environment. Even if you want to use the remote box still, if you use cygwin and launch an xterm with it, you could ssh -X <host> and that will export your DISPLAY to that remote machine so it can display back on your windows machine.
As I mentioned in the comment under Eric Renouf answer, I am working thru the same book. That part of the book have some testing of creating users, groups, shifting users, group permissions etc. I found that I needed to log the same user out quite some times. The last time logging that user out, I got a message saying xlogo is terminatet, like it was hanging on that user?
After everyone was logged out, I logged in as sudo and everything worked again.
I know this question has been asked several times around the internet, but I have spent about a week trying to solve this problem with little luck.
I am trying to install JavaCommAPI (an archived Java package to allow communication with rs232) on a remote linux Ubuntu 11.0, 32-bit server in order to deploy a web project which I have developed on a local apache server on my windows PC.
The thing that puzzles me is, I am able to get the .war web project to deploy on a local apache server on a separate 32-bit LinuxMint16 PC by correctly placing the javax.comm.properties, comm.jar, and libSerialParallel.so files in their respective places.
I use System.getProperty("java.library.path"); in order to find the correct library path in order to install correct files.
On my LinuxMint16:
javax.comm.properties -- /usr/lib/jvm/java-7-openjdk-i386/jre/lib
comm.jar -- /usr/lib/jvm/java-7-openjdk-i386/jre/lib/ext
libSerialParallel.so -- /usr/lib/jvm/java-7-openjdk-i386/jre/lib/i386
....works!
On my remote Ubuntu server I did the exact same for its reported library path
(for example: /usr/local/jdk/jdk1.7.0_45/jre/lib/javax.comm.properties ;
/usr/local/jdk/jdk1.7.0_45/jre/lib/ext/comm.jar ;
/usr/local/jdk/jdk1.7.0_45/jre/lib/i386/libSerialParallel.so)
...fails =(
Things of note: I added the needed apache jars and comm.jar to my libraries in Eclipse using the BuildPath wizard (right click on project --> Build Path-->add external jars) which points to local files on my PC which I obviously cannot use for a remote server which I am only accessing through command line. May this is affecting it somehow?
I tried to get error output (System.err) from the Java Console printed to a separate file for my remote server as that feedback was very helpful in getting all the files sorted on my LinuxMint PC.
PrintStream ps = new PrintStream(pathName);
System.setOut(ps);
System.setErr(ps);
Which again, is oddly working beautifully to print the stream to a local .txt file on my LinuxMintPC but not to the one I designate on my remote ubuntu server.
I am really at a wits end here!! Am I mixing and matching appropriate versions of Systems prohibiting things to run smoothly? I am not sure how to proceed from here, if anyone has any insights I would die of happiness. Thanks
I needed to install OPEN JDK7 on my ubuntu, put files in appropriate library paths (as described above) and now it works.
