Thanks for reporting this problem.

No, this is not normal or expected.

Perhaps you could manually run the postinstall script with 'sh -x 
/etc/postinstall/xlaunch.sh.done' to see where it is getting stuck?

Hello,
Please find attached the script /etc/postinstall/xlaunch.sh and the 
output of its execution (file postinstall_xlaunch.txt).
Thank you.
Best regards,

Thanks.

I guess this doesn't reproduce the problem (freezing), as this is just 
what I would expect to see when running the script without the PATH set?

Perhaps you could try again from a cygwin bash shell?

Re: Installer of Cygwin 64 seems to freeze when executing /etc/postinstall/xlaunch.sh - version 2.874

[Jean-Paul Bouchet]

Hello,
May be is the value of PATH the problem?
When I launch, by a double click on the bash.exe file, a cygwin bash 
shell (C:\cygwin64\bin\bash.exe) and I display $PATH, I don't find any 
cygwin directory in the list, but a list of windows directories:
/cygdrive/c/Windows/system32:/cygdrive/c/Windows:/cygdrive/c/Windows/System32/Wbem: 
...

So, when I execute in the cygwin bash shell  the command '/bin/sh -x 
/etc/postinstall/xlaunch.sh.done', I get the same errors than those I 
get when I execute 'C:\cygwin64\bin\sh -x 
/etc/postinstall/xlaunch.sh.done' in the windows command interpreter:
the command 'uname' is unknown.

If I change the value of PATH with PATH=/cygdrive/c/cygwin64/bin:$PATH 
and export PATH, the execution of 'sh -x 
/etc/postinstall/xlaunch.sh.done' don't give any errors.

What is the value of PATH when the installation executes the set of 
postinstall scripts ?

This isn't what Jon meant by starting a Cygwin bash shell.  Do it by 
clicking on the Cygwin Terminal shortcut created by setup.  If it didn't 
create one, rerun setup.  On the last screen, check the box asking setup 
to create one.

As Ken Brown has explained, double-clicking bash.exe does not set the PATH.

You should run it from the "Cygwin Terminal" shortcut, which starts a 
login shell, which reads profile scripts, which set the PATH appropriately.

setup cleans the PATH to start with '/bin:/usr/sbin:/sbin', and contain 
any directories in the existing PATH which start with the windows system 
directory (e.g. '/cygdrive/cWindows/System32')

Again, having an incorrect PATH doesn't reproduce the problem of the 
script freezing, so I don't think this is the underlying cause of the 
problem you see.
