I can't remove or install package, file /etc/setup/setup.rc is exist and readable. here the log

$ apt-cyg install unzip
awk: cmd. line:2: warning: escape sequence `\<' treated as plain `<'
awk: cmd. line:3: fatal: cannot open file `/etc/setup/setup.rc' for reading (No such file or directory)
awk: cmd. line:6: fatal: cannot open file `/etc/setup/setup.rc' for reading (No such file or directory)
mkdir: cannot create directory '//x86': Read-only file system
/usr/bin/apt-cyg: line 158: cd: //x86: No such file or directory
Installing unzip
Unable to locate package unzip

found solution, replace awk with gawk because awk is not valid cygwin package

now can become problem, it trying to remove /usr/bin

$ apt-cyg remove unzip
Removing unzip
rmdir: failed to remove '/usr/bin/'
Package unzip removed

Please try reinstall cygwin, because there should be a softlink there awk to gawk

mobj@BPOLMOBJ1 /cygdrive/c/Users/mobj
$ ls -l /usr/bin/gawk
-rwxrwxr-x+ 2 mobj BPINTRA+Group(513) 574995 Jun  1  2015 /usr/bin/gawk

mobj@BPOLMOBJ1 /cygdrive/c/Users/mobj
$ ls -l /usr/bin/awk
lrwxrwxrwx 1 mobj BPINTRA+Group(513) 8 Jan 20 13:43 /usr/bin/awk -> gawk.exe

awk is exist, maybe file encoding problem.
