do-release-upgrade causing tracebacks with no_longer_supported string

[Brian Murray]

The no longer supported error message is causing tracebacks for some translations. Here is the code from do-release-upgrade:

120 # make sure to inform the user if his distro is no longer supported
121 # this will make it appear in motd (that calls do-release-upgrade in
122 # check-new-release mode)
123 if m.no_longer_supported is not None:
124 url = "http://www.ubuntu.com/releaseendoflife"
125 print(_("Your Ubuntu release is not supported anymore."))
126 print(_("For upgrade information, please visit:\n"
127 "%(url)s\n") % { 'url' : url })

Here is the Traceback.

Traceback (most recent call last):
  File "/usr/bin/do-release-upgrade", line 123, in <module>
    "%(url)s\n") % { 'url' : url })
ValueError: unsupported format character '?' (0xa) at index 44

One bucket of these can be found in the Error Tracker at:

We can see this is an issue with the ru translation.

#: ../do-release-upgrade:122
msgid ""
"For upgrade information, please visit:\n"
"%(url)s\n"
msgstr ""
"Для получения информации об обновлении посетите:\n"
"%(url)\n"

Notice the missing "s".

The it translation switches the % to a $.

#: ../do-release-upgrade:122
msgid ""
"For upgrade information, please visit:\n"
"%(url)s\n"
msgstr ""
"Per informazioni sull'avanzamento consultare:\n"
"$(url)s\n"

mvo - Do you have any ideas how we can avoid this in the future? Does "%(url)s\n" need to be translatable?
