Package: needrestart
Version: 3.5-4+deb11u2
Severity: normal

Dear Maintainer,

When running 'needrestart -b' on an AMD system, I get the following
uninitialized variable warning. It also does not report the expected
microcode version (NEEDRESTART-UCEXP). See output: section below for
example output of needrestart -b.

Use of uninitialized value $ucode_vars{"AVAIL"} in concatenation (.) or string at /usr/sbin/needrestart line 904.

This perl warning disappears when adding the -v option (needrestart -b -v),
and the correct value is reported for NEEDRESTART-UCEXP.


It looks to me like the problem is that line 182 of
/usr/share/perl5/NeedRestart/uCode/AMD.pm ends in a comma (,) instead
of a semicolon (;). This means that assignment is subsumed into the
next line which is under if ($debug).

See the attached patch. The debsum error reported below is due to my
applying this patch.

Thanks,
George Robbert
