I don't have a magic pill for you.  But I have a few comments:

1) Turn off autoindent when pasting multi-line text into your email.
   If you're in vim, you can do that with ":set paste" or ":set noai".

2) You didn't tell us what command you ran that failed.  Was that error
   during the "apt-get upgrade" phase, or the "apt-get dist-upgrade"
   phase?  Did you even follow the directions?  We have no idea.

3) libcrypt.so.1 is in the libcrypt1 package.  If that's gone missing,
   you might want to try installing it directly.  If that doesn't work,
   maybe extract it by hand (using dpkg -x in some temp directory),
   and move the shared library to where it needs to be.

unicorn:~$ dpkg -L libcrypt1:amd64
/.
/lib
/lib/x86_64-linux-gnu
/lib/x86_64-linux-gnu/libcrypt.so.1.1.0
[...]

So, move the shared library file from the temp directory to that place,
run /sbin/ldconfig (to generate the libcrypt.so.1 symlink) and pray.
