Comment 57 for bug 1604750

Hi,
The patch method expects the updates_available file is in its original condition and to be the same as mine. Have you modified it before this or perhaps its older or from a different version of byobu/Ubuntu ? If so that is probably the reason it failed.
Which is why I also posted the complete updates_available file in post #50, so that it could be saved and used as is.

But also here are the 2 differences I made to the file if you make the changes by hand:

at line 53 -
orig:

    flock -xn "$flock" /usr/lib/update-notifier/apt-check 2>&1 | awk '-F;' 'END { print $1, $2 }' >"$mycache" 2>/dev/null &

changes to:

    flock -xn "$flock" sh -c "(rm -f \"$mycache\" ; /usr/lib/update-notifier/apt-check 2>&1 | awk '-F;' 'END { print \$1, \$2 }' >\"${mycache}-x\" 2>/dev/null ; sleep 5 ; mv \"${mycache}-x\" \"$mycache\") &"

at line 88 -

orig:

    [ "/var/lib/apt" -nt "$mycache" ] || [ "/var/lib/apt/lists" -nt "$mycache" ]

changes to:

    [ "/var/lib/apt" -nt "$mycache" ] || [ "/var/lib/apt/lists" -nt "$mycache" ] || [ "/var/log/dpkg.log" -nt "$mycache" ]

(this line 88 change was made a long time ago as mentioned above)

NOTE: both these changes are each a single line - the above may have shown up as multiple lines, but they are really each a long single line.
