ubuntu-support-status return "TypeError: not enough arguments for format string" due to bad translations

I wasn't able to recreate this issue e.g. the original code works fine for me.

That being said it certainly appears to be an issue affecting a lot of people:

https://errors.ubuntu.com/problem/76dc05ff3a34f1b74353bf3103378e872e58dea2

There about 260 reports from 16.04 users regarding it.

Well some of them in errors are due to bad translations. From it.po:

2468 #: ../ubuntu-support-status:145
2469 msgid "You have %(num)s packages (%(percent).1f%%) supported until %(time)s"
2470 msgstr "Ci sono %(num)s pacchetti (%percent).1f%%) supportati fino a %(time)s"

Notice the missing ( in (%percent).

gd.po:msgid "You have %(num)s packages (%(percent).1f%%) supported until %(time)s"
gd.po-msgstr "Tha agad % (num)s pacaidean (%(percent).1f%%) le taic gu %(time)s"

lt.po:msgid "You have %(num)s packages (%(percent).1f%%) supported until %(time)s"
lt.po-msgstr "Jūs turite %(num)s paketų (%(percent).1f %%) palaikomų iki %(time)s"

sl.po:msgid "You have %(num)s packages (%(percent).1f%%) supported until %(time)s"
sl.po-msgstr "Imate %(num) paketov (%(percent).1f%%), ki so podprti do %(time)"

Status changed to 'Confirmed' because the bug affects multiple users.
