Installing and Updating Cygwin Packages

Installing and Updating Cygwin for 64-bit versions of Windows

Run setup-x86_64.exe any time you want to
update or install a Cygwin package for 64-bit windows.

The signature
for setup-x86_64.exe can be used to verify the
validity of this binary using the public
key here.

General installation notes

When installing packages for the first time, the setup program
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 program 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. The setup program
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,
the setup program will remember what you selected, so re-running it
will update your system with any new package releases.

The setup program 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 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 program understands
command-line
arguments 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.

Q: How do I verify the signature of setup?

A: e.g.

$ gpg --recv-key 1A698DE9E2E56300
gpg: requesting key 1A698DE9E2E56300 from hkp server keys.gnupg.net
gpg: key 1A698DE9E2E56300: "Cygwin <cygwin@cygwin.com>" imported
gpg: 3 marginal(s) needed, 1 complete(s) needed, PGP trust model
gpg: depth: 0  valid:   8  signed:   2  trust: 0-, 0q, 0n, 0m, 0f, 8u
gpg: depth: 1  valid:   2  signed:   0  trust: 2-, 0q, 0n, 0m, 0f, 0u
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

$ gpg --keyid-format=long --with-fingerprint --verify setup-x86_64.exe.sig setup-x86_64.exe
[...]
gpg: Signature made 12 Mar 2020 16:26:58 GMT
gpg:                using RSA key 1A698DE9E2E56300
gpg: Good signature from "Cygwin <cygwin@cygwin.com>"
Primary key fingerprint: 5640 5CF6 FCC8 1574 682A  5D56 1A69 8DE9 E2E5 6300

Q: What’s the hash of setup?

A: See here

Q: How can I do an offline install?

A1: Install without access to the internet, using a local package
repository

• Create a local copy of the package repository e.g. by
  using rsync on one
  of the mirrors.
• Move that copy to an accessible location, or copy it to removable media.
• Run setup, and enter the URL, path or UNC path of that repository when
  prompted to «Choose A Download Site».

A2: Install without access to the internet, using setup’s separate download
and install actions.

• Run setup in «Download without installing» mode somewhere it can access a
  mirror, with the desired packages selected.
• Run setup again in «Install from local directory» mode, with the same «Local
  package directory», and set of packages selected.

Q: How can I install the last Cygwin
version for an old, unsupported Windows?

A: Run setup with the options --allow-unsupported-windows
--site circa_URL:

A note about 32-bit Cygwin

The limited address space of 32-bit Windows means that
random
failures in the fork(2) system call are more likely. Therefore, we
recommend using 32-bit Cygwin only in limited scenarios, with only a minimum
of necessary packages installed, and only if there’s no way to run 64-bit
Cygwin instead.

You have been warned. If you’re still sure you really need a 32-bit
Cygwin, and there’s absolutely no way around it, you may use
the setup-x86.exe installer, following the
instructions above. The signature can be
used to verify the validity of this binary.

Q: How do I help improve setup?

A: See the setup
project page for more information.
