Cygwin broken after update (PATH problem?)

Your /etc/profile has DOS-style CRLF line endings.

You will, I'm sure, not have updated your version of bash without reading
the relevant release announcement, so I am sure you will see at once what the
problem is and one of the recommended solutions will work just fine for you.

After I had observed that my bash doesn't work anymore, I repeated the
setup, to give it
a chance to cleanup any inconsistencies, but it didn't change anything.

It won't overwrite a locally-modified /etc/profile, that's deliberate.

Well, the problem is that there *is* no /etc/profile at all.

You will, I'm sure, not have updated your version of bash
without reading
the relevant release announcement,

What type of announcement? I went to http://cygwin.com/ (on this
page, there is definitely no "release announcement" to see), then
clicked on "install or update", which executed setup, then I got
a list of possible packages (in which I added a few), and let it
run.

Isn't this the way an update is supposed to be done?

It won't overwrite a locally-modified /etc/profile, that's
deliberate.

And it is a good thing to do. So it seems that setup did not overwrite,
but delete it, which is really kind of strange.

Well, that tells us two things:

1) Setup must have failed part-way through. Normally re-running it, with
"Install from local package directory", and clicking through all the default
options, and letting it run to completion should fix any problems, but I see
you tried that already. Hmm.

2) One or more of your /other/ bash startup scripts has CRLF line-endings.
TMI!

The release announcements, that are posted to the cygwin-announce list as
well as to the main cygwin list, every time that a cygwin package is updated.
Weren't you curious about what updates you were going to get and in what way
they would be different from what you already had installed? This one:

http://cygwin.com/ml/cygwin-announce/2006-09/msg00006.html

seems to explain at least part of your problem: self-overwriting error
messages are a sign of CRLF line-ends.

Not all the documentation at the cygwin.com website is on the front page.
It wouldn't all fit. You're expected to have browsed the docs, faq and
mailing-list summaries of your own accord. (The fact that you're here
suggests you /did/ read the mailing-list summary page...)

Yes, it is; it seems something has gone wrong.

Yep, it's absolutely not meant to do that. Which means that something went
badly wrong, but it's a bit hard to guess what.

If setup.exe doesn't repair the system for you, you can get a fresh copy of
/etc/profile out of /etc/defaults/etc. Hmm, you probably want bash.basrc from
there as well, that seems to be missing from your /etc listing. Try copying
those two files across, then see what you get, and don't forget to try d2u'ing
your ~/.bashrc and ~/.bash_profile.

No, I run setup again from the *website*. But I think this must
be even more safer than just doing it locally.

Honestly, no, not at all. Yes, this makes me an ignorant, but the
main reason I went to redo the setup, was that I wanted to install
a new package, and when doing this I thought it might be a good
idea to update everything, to get the most recent bug fixes
and so on. So I wasn't that interested in new features.

I see. Indeed I did modify the profile, and although I normally take
care about
the line endings (the editor is set to keep line endings style), it
might be
that I also had used on one occasion a different editor which did not
observe
this policy. Not very likely, but I don't want to rule out this
possibility.

But this would not explain why the /etc/profile got *erased*.

However, the announcement says that one should not have bash running
while
doing the setup. I think I did have a cygwin window open, running zsh on
top of bash.

Yes, I misunderstood you here. I thought you wanted to suggest that
the announcements of the most recent release were supposed to be
always published on the front page (or at least represented via a
direct link, as it is the case on some other software homepages).

Actually, it's meant to do exactly that. The way the /etc files are
upgraded is this: the postinstall script adds the local versions of the
files if they aren't there already and keeps the copy of the original.
Upon uninstall, the preremove script compares the local version with the
original, and if they are the same, removes the local version. Then,
after installing the new version of the package (hence, the new original),
the original is again copied to the local version if it's not present.

What seems to have happened is that the preremove script ran fine (and
removed the local copy), but the postinstall didn't run (so the new local
copy did not get created).

One thing to try would be temporarily adding a text mount for /etc and
seeing if it helps. If it does, then one of the postinstall scripts may
accidentally have CRLF line endings (which would be a packaging bug).
The mount can be removed after the install.

Well, the non-abbreviated phrase would be "a text-mode mount". As to how
to add one, read "man mount".
