After seeing the method of this post, I was trying to install liblapack0 in cygwin from the command line:
setup-x86.exe ^
--quiet-mode ^
--packages ^
liblapack0
But it seems it does not work. While I can see liblapack0 in the GUI of cygwin. Even, in ubuntu via apt-get, I cannot install it:
$ sudo apt-get install liblapack0
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package liblapack0
My question is that if I have the name of an item in cygwin GUI, how can I find its related package?

As the title says I am trying to install the perl module perl-Net-SSH2. I have tried via yum but get an error that no package is available.
yum install perl-Net-SSH2
I have tried by downloading an rpm file but the only one I can find is for el6 and it complains about the version of perl
yum localinstall perl-Net-SSH2-0.45-4.el6.x86_64.rpm
Requires: perl(:MODULE_COMPAT_5.10.1)
I have tried downloading the source code but get told "Unable to find a working version of library ssh2 in the following directories" even though it is installed. (via yum install libssh2 libssh2-devel)
I have tried via cpan but get the same error "Unable to find a working version of library ssh2 in the following directories"
Any ideas? Google is very sketchy on this and only
OK, I solved this while writing the question. Seeing as information on this is limited I thought it would be worth posting the question anyway. The error message was giving the wrong information in that it was actually gcc that was missing, not libssh2. These are the steps I followed. I've tried to make it as verbatim as possible. I have not verified all these modules are required but this is what I installed before compiling it.
yum install libssh2 libssh2-devel
yum install openssl openssl-devel
yum install perl-Net-SSLeay
yum install gcc
Search for Net::SSH2 in google
Click the link "Net::SSH2 - search.cpan.org"
Download source code (tar.gz file)
Copy it to your redhat 7 machine
tar -xvf Net-SSH2-0.62.tar.gz
cd Net-SSH2-x.xx
perl Makefile.PL
make
make install
Should all be working now, test it with
perl -e 'use Net::SSH2;'
Following this guide but unable to install cfdisk.
sudo apt-get install cfdisk
returns

This is because the cfdisk utility is not shipped in a cfdisk package but in the util-linux package.
aptitude install util-linux
When I am trying to install sbt in Ubuntu as it is suggested here:
wget http://apt.typesafe.com/repo-deb-build-0002.deb
sudo dpkg -i repo-deb-build-0002.deb
sudo apt-get update
sudo apt-get install sbt
The last command sudo apt-get install sbt asks if I want to install GJI -- GNU java interpreter.
The following extra packages will be installed:
gcj-4.5-jre gcj-4.5-jre-headless
Suggested packages:
fastjar gcj-4.5-jdk
The following NEW packages will be installed:
gcj-4.5-jre gcj-4.5-jre-headless sbt
I do not want to install it. How can I install an sbt package in Ubuntu without GCJ ?
You can go on the sbt website, download it,extract it somewhere in your home directory and add it in the path.
I have it on ~/apps/sbt/ and i added the following in the end of ~/.bashrc
export PATH=$HOME/apps/sbt/bin:$PATH
I found it the simplest way to achive this because the apt typesafe respository is outdated.
I am writing a post-install script for Ubuntu in Perl (same script as seen here). One of the steps is to install a list of packages. The problem is that if apt-get install fails in some of many different ways for any one of the packages the script dies badly. I would like to prevent that from happening.
This happens because of the ways that apt-get install fails for packages that it doesn't like. For example when I try to install a nonsense word (i.e. typed in the wrong package name)
$ sudo apt-get install oblihbyvl

but if instead the package name has been obsoleted (installing handbrake from ppa)

Package handbrake is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'handbrake' has no installation candidate
$ apt-cache search handbrake
handbrake-cli - versatile DVD ripper and video transcoder - command line
handbrake-gtk - versatile DVD ripper and video transcoder - GTK GUI
etc, etc ...
I have tried parsing the results of apt-cache and apt-get -s install to try to catch all possibilities before doing the install, but I seem to keep finding new ways to allow failures to continue to the actual install system command.
My question is, is there some facility either in Perl (e.g. a module, though I would like to avoid installing modules if possible as this is supposed to be the first thing run after a new install of Ubuntu) or apt-* or dpkg that would let me be sure that the packages are all available to be installed before installing and if not fail gracefully in some way that lets the user decide what to do?
N.B. I am doing something along the lines of:
my #list_of_install_candidates = (...);
my #to_install = grep { my $output = qx{ apt-get -s install $_ }; parse_output($output); } #list_of_install_candidates;
system('apt-get', 'install', #to_install);
You might try apt-cache policy. examples:
$ apt-cache policy handbrake
handbrake:
Installed: (none)
Candidate: (none)
Version table:
$ apt-cache policy foo
N: Unable to locate package foo
$ apt-cache policy openbox
openbox:
Installed: 3.4.11.1-1
Candidate: 3.4.11.1-1
Version table:
*** 3.4.11.1-1 0
500 http://mirrors.xmission.com/ubuntu/ maverick/universe i386 Packages
100 /var/lib/dpkg/status
Anything with a non-blank version table should be installable.
