Are you aware that these stipulations will exclude a "linux-something" at the lines end from being removed because there will be no space afterwards? Maybe this is not what you want. Also notice that your clause 2 means that the space immediately following the word "linux-*" will be removed too.
If your goal is indeed to remove the last match too i'd suggest:
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:
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.

wall
WALL(1) User Commands WALL(1)NAME
wall -- write a message to users
SYNOPSIS
wall [-n] [-t TIMEOUT] [file]
DESCRIPTION
Wall displays the contents of file or, by default, its standard input, on the terminals of all currently logged in users. The command will
cut over 79 character long lines to new lines. Short lines are white space padded to have 79 characters. The command will always put carriage
return and new line at the end of each line.
Only the super-user can write on the terminals of users who have chosen to deny messages or are using a program which automatically denies
messages.
Reading from a file is refused when the invoker is not superuser and the program is suid or sgid.
OPTIONS -n, --nobanner
Supress banner
-t, --timeout TIMEOUT
Write timeout to terminals in seconds. Argument must be positive integer. Default value is 300 seconds, which is a legacy from
time when people ran terminals over modem lines.
-V, --version
Output version and exit.
-h, --help Output help and exit.
SEE ALSO mesg(1), talk(1), write(1), shutdown(8)HISTORY
A wall command appeared in Version 7 AT&T UNIX.
AVAILABILITY
The wall command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
