If your goal is indeed to remove the last match too i'd suggest:

Code:
sed 's/linux-[^ ]* \{0,1\}//g' /path/to/file

If you want to retain the blank following the word but would not want to add a space at the end of the string then this:

Code:
sed 's/linux-[^ ]*\( \{0,1\}\)/\1/g' /path/to/file


I hope this helps.

Any of the two work, because the apt command uses space as argument separator, when there are one or more spaces at the end they are ignored and two or more spaces in any place are condensed into one.

ctrlaltdel

CTRLALTDEL(8)						       System Administration						     CTRLALTDEL(8)

NAME

       ctrlaltdel - set the function of the Ctrl-Alt-Del combination

SYNOPSIS

       ctrlaltdel hard|soft

DESCRIPTION

       Based  on examination of the linux/kernel/sys.c code, it is clear that there are two supported functions that the Ctrl-Alt-Del sequence can
       perform: a hard reset, which immediately reboots the computer without calling sync(2) and without any other preparation; and a soft  reset,
       which sends the SIGINT (interrupt) signal to the init process (this is always the process with PID 1).  If this option is used, the init(8)
       program must support this feature.  Since there are now several init(8) programs in the Linux community, please consult	the  documentation
       for the version that you are currently using.

       ctrlaltdel is usually used in the /etc/rc.local file.

OPTIONS

       -V, --version
	      Output version information and exit.

       -h, --help
	      Display help and exit.

FILES

       /etc/rc.local

SEE ALSO

       init(8)

AUTHOR

       Peter Orbaek <poe@daimi.aau.dk>

AVAILABILITY

       The  ctrlaltdel	command is part of the util-linux package and is available from Linux Kernel Archive <ftp://ftp.kernel.org/pub/linux/utils
       /util-linux/>.
