How to Fix Cygwin Setup Internal Error Gcrypt Library Error 60 Illegal Tag
Introduction
What is Cygwin?
Cygwin is a software that allows you to run Linux-like applications and commands on Windows. It consists of a DLL (cygwin1.dll) that provides a POSIX-compatible layer over Windows, and a collection of tools and utilities that emulate the Unix environment. With Cygwin, you can access many standard Unix programs, such as bash, gcc, make, grep, sed, awk, ssh, scp, rsync, etc. You can also compile and run programs written for Unix on Windows, using the Cygwin API or the Win32 API.
Cygwin Setup Internal Error Gcrypt Library Error 60 Illegal Tag
What is gcrypt library error 60 illegal tag?
Gcrypt library error 60 illegal tag is an error message that appears when you try to install or update Cygwin using a setup program that is outdated or corrupted. It means that the setup program cannot verify the signature of the setup.ini file from the mirror site you selected. The setup.ini file contains information about the available packages and their dependencies. If the setup program cannot read this file, it cannot proceed with the installation or update.
Causes of the Error
Outdated or corrupted setup program
One of the most common causes of this error is using an old or damaged version of the setup program. The setup program is responsible for downloading and installing the Cygwin packages from the internet. However, if the setup program is not compatible with your system architecture (32-bit or 64-bit), or if it has been modified by malware or other factors, it may fail to work properly. In particular, it may not be able to handle the new format of the setup.ini file that was introduced in 2017 to support both x86 and x64 architectures.
Incompatible or unsupported mirror site
Another possible cause of this error is choosing a mirror site that does not have a valid or updated setup.ini file. A mirror site is a server that hosts a copy of the Cygwin files for faster and easier access. However, not all mirror sites are maintained regularly or have the same version of the files as the official Cygwin site. Some mirror sites may have corrupted or missing files, or may not support your system architecture. If you select such a mirror site, the setup program may not be able to download or verify the setup.ini file.
Incorrect proxy settings or firewall issues
A third possible cause of this error is having incorrect proxy settings or firewall issues that prevent the setup program from accessing the internet. A proxy server is a computer that acts as an intermediary between your computer and the internet. It can be used to improve security, privacy, or performance. However, if the proxy server is not configured properly, or if it requires authentication, it may block or interfere with the setup program's connection. Similarly, a firewall is a software or hardware that monitors and controls the incoming and outgoing network traffic. It can be used to protect your computer from unauthorized or malicious access. However, if the firewall is too strict or has incorrect rules, it may prevent the setup program from downloading or verifying the setup.ini file.
Solutions for the Error
Download and run the latest setup program
The first and easiest solution for this error is to download and run the latest version of the setup program from the official Cygwin website. The latest setup program is compatible with both 32-bit and 64-bit systems, and can handle the new format of the setup.ini file. To download and run the latest setup program, follow these steps:
Go to https://cygwin.com/install.html and click on the link that matches your system architecture (setup-x86.exe for 32-bit systems or setup-x86_64.exe for 64-bit systems).
Save the setup program to a convenient location on your computer.
Run the setup program as an administrator by right-clicking on it and selecting "Run as administrator".
Follow the instructions on the screen to install or update Cygwin.
Choose a different mirror site or download source
The second solution for this error is to choose a different mirror site or download source that has a valid and updated setup.ini file. To choose a different mirror site or download source, follow these steps:
Run the setup program as an administrator by right-clicking on it and selecting "Run as administrator".
On the "Choose Installation Type" screen, select "Install from Internet" or "Download Without Installing".
On the "Choose Download Site(s)" screen, uncheck the mirror site that caused the error and select another one from the list. You can also click on "Add" to enter a custom URL for a download source.
Click on "Next" and continue with the installation or update process.
Adjust the proxy settings or disable the firewall temporarily
The third solution for this error is to adjust the proxy settings or disable the firewall temporarily to allow the setup program to access the internet. To adjust the proxy settings or disable the firewall temporarily, follow these steps:
Run the setup program as an administrator by right-clicking on it and selecting "Run as administrator".
On the "Choose Installation Type" screen, select "Install from Internet" or "Download Without Installing".
On the "Choose A Download Source" screen, click on "Direct Connection" if you are not using a proxy server, or click on "Use Internet Explorer Proxy Settings" if you are using a proxy server that is configured in Internet Explorer. You can also click on "User URL" to enter a custom proxy URL.
Click on "Next" and continue with the installation or update process.
If you still encounter the error, you may need to temporarily disable your firewall software or hardware. Refer to the documentation or support of your firewall provider for instructions on how to do this.
After you finish installing or updating Cygwin, remember to enable your firewall again for security reasons.
