General installation notes When installing packages for the first time, setup.exe does not install every package. Only the minimal base packages from the Cygwin distribution are installed by default, which takes up about 100 MB. Clicking on categories and packages in the setup.exe package installation screen allows you to select what is installed or updated. Individual packages like bash, gcc, less, etc. Are released independently of the Cygwin DLL, so the Cygwin DLL version is not useful as a general Cygwin release number.

There is no byobu package in Cygwin, but installing it from source is easy: Install tmux and make using the Cygwin package installer. Download the latest release of Byobu from here and unzip it.
The setup.exe utility tracks the versions of all installed components and provides the mechanism for installing or updating everything available from this site for Cygwin. Once you've installed your desired subset of the Cygwin distribution, setup.exe will remember what you selected so rerunning the program will update your system with any new package releases. On Windows Vista and later, setup.exe will check by default if it runs with administrative privileges and, if not, will try to elevate the process. If you want to avoid this behaviour and install under an unprivileged account just for your own usage, run setup.exe with the -no-admin option.
Q: How do I add a package to my existing Cygwin installation? A: Run the setup program and select the package you want to add. Tip: if you don't want to also upgrade existing packages, select 'Keep' at the top-right of the package chooser page. Q: Is there a command-line installer? A: Yes and no. The setup.exe program understands which allow you to control its behavior and choose individual packages to install. While this provides some functionality similar to such tools as apt-get or yum it is not as full-featured as those package managers.
Q: Why not use apt, yum, my favourite package manager, etc.? A: The basic reason for not using a more full-featured package manager is that such a program would need full access to all of Cygwin's POSIX functionality.
That is, however, difficult to provide in a Cygwin-free environment, such as exists on first installation. Additionally, Windows does not easily allow overwriting of in-use executables so installing a new version of the Cygwin DLL while a package manager is using the DLL is problematic. Q: How do I install everything? A: You do not want to do this! This will install an enormous number of packages that you will never use, including debuginfo and source for every package. If you really must do this, clicking on the 'Default' label next to the 'All' category to change it to 'Install' will mark every Cygwin package for installation. Be advised that this will download and install tens of gigabytes of files to your computer.

There exist some scripts, which can be used as simple package managers for Cygwin. But it’s important to know, that they always will be quite limited, because of.ehm.Windows. Installing or removing packages is fine, each package manager for Cygwin can do that. But updating is a pain since Windows doesn’t allow you to overwrite an executable, which is currently running. So you can’t update e.g.
Cygwin DLL or any package which contains the currently running executable from the Cygwin itself. There is also this note on the page: 'The basic reason for not having a more full-featured package manager is that such a program would need full access to all of Cygwin’s POSIX functionality. That is, however, difficult to provide in a Cygwin-free environment, such as exists on first installation.

Cygwin’s setup uses Windows registry to overwrite executables which are in use and this method requires a reboot of Windows. Therefore, it’s better to close all Cygwin processes before updating packages, so you don’t have to reboot your computer to actually apply the changes. Installation of a new package should be completely without any hassles. I don’t think any of package managers except of Cygwin’s setup.exe implements any method to overwrite files in use, so it would simply fail if it cannot overwrite them.
Some package managers for Cygwin: Update: the repository was disabled recently due to copyright issues. It the owner of the repository issued the DMCA takedown on his own repository and created a new project called Sage (see bellow). The best one for me.
Simply because it’s one of the most recent. It doesn’t use Cygwin’s setup.exe, it rather re-implements, what setup.exe does. It works correctly for both platforms - x86 as well as x8664. There are a lot of forks with more or less additional features. For example, the is one of the improved versions, which is really great. Apt-cyg is just a shell script, there is no installation.
Just download it (or clone the repository), make it executable and copy it somewhere to the PATH: chmod +x apt-cyg # set executable bit mv apt-cyg /usr/local/bin # move somewhere to PATH #.and use it: apt-cyg install vim There is also with different features. Another package manager implemented as a shell script. I didn't try it but it actually looks good. It can search for packages in a repository, list packages in a category, check dependencies, list package files, and more.
It has features which other package managers don't have. Fork of abandoned original with improvements and bugfixes. It has quite a lot of features and it's implemented in Python. Installation is made using make. If you used Chocolatey to install Cygwin, you can install the package cyg-get, which is actually a simple wrapper around Cygwin’s setup.exe written in PowerShell. Cygwin’s setup.exe It also has a.
Moreover, it allows you to upgrade all installed packages at once (as apt-get upgrade does on Debian based Linux). Example use: setup-x8664.exe -q -packages=bash,vim You can create an alias for easier use, for example: alias cyg-get='/cygdrive/d/path/to/cygwin/setup-x8664.exe -q -P' Then you can, for example, install Vim package with: cyg-get vim. Sage is a fork of apt-cyg by its most active contributors over the past year or two (Steven Penny). It appears that earlier this year he had some disagreement with the original apt-cyg author (Stephen Jungels) and issued the DMCA takedown when he forked the project.
Since Jungels (aka Transcode) is verifiably the original author of the project, GitHub restored the original project soon after. Currently, both projects are available – though the original project hasn't had any new code updates since the split. It’s a messy situation, really. – Dec 9 '16 at 13:26.
