apt.sh outputs wrong arch label

Original issue prometheus/node_exporter#1462

Current apt.sh script:

/usr/bin/apt-get --just-print upgrade \
  | /usr/bin/awk -F'[()]' \
      '/^Inst/ { sub("^[^ ]+ ", "", $2); sub("\\[", " ", $2);
                 sub(" ", "", $2); sub("\\]", "", $2); print $2 }' \
  | /usr/bin/sort \
  | /usr/bin/uniq -c \
  | awk '{ gsub(/\\\\/, "\\\\", $2); gsub(/\"/, "\\\"", $2);
           gsub(/\[/, "", $3); gsub(/\]/, "", $3);
           print "apt_upgrades_pending{origin=\"" $2 "\",arch=\"" $3 "\"} " $1}'

Outputs wrong arch => arch="Debian/Ubuntu".

apt_upgrades_pending{origin="PostgreSQLfor",arch="Debian/Ubuntu"} 2
apt_upgrades_pending{origin="PostgreSQLfor",arch="Debian/Ubuntu"} 4
apt_upgrades_pending{origin="Ubuntu:18.04/bionic-updates",arch="all"} 19
apt_upgrades_pending{origin="Ubuntu:18.04/bionic-updates",arch="amd64"} 54
apt_upgrades_pending{origin="Ubuntu:18.04/bionic-updates,Ubuntu:18.04/bionic-security",arch="all"} 13
apt_upgrades_pending{origin="Ubuntu:18.04/bionic-updates,Ubuntu:18.04/bionic-security",arch="amd64"} 42
apt_upgrades_pending{origin="universe-updates/201907312020bionic:bionic",arch="all"} 2
apt_upgrades_pending{origin="universe-updates/201907312020bionic:bionic",arch="amd64"} 3

The raw data that the script processes (I took only the PostgreSQLfor parts which relate to the duplication):

$ /usr/bin/apt-get --just-print upgrade |grep 'PostgreSQL for'

apt.sh was replaced in #99. Can this be closed?

[dswarbrick]

Yes. We won't bring apt.sh back down from the attic.

@dswarbrick you might also want to close #44 (I'm not the reporter, neither a project member, so I feel I shouldn't do it)
