[Bug 1563025] Re: 'last' command output is wrong

[Richard Hickling]

It seems the specific lines that cause this in my particular case are:

```
[1] [00000] [~~  ] [shutdown] [~           ] [6.2.0-1018-aws      ] [0.0.0.0        ] [2024-11-10T19:08:47,195287+00:00]
[2] [00000] [~~  ] [reboot  ] [~           ] [6.8.0-1018-aws      ] [0.0.0.0        ] [2024-11-10T19:08:53,261639+00:00]
[1] [00053] [~~  ] [runlevel] [~           ] [6.8.0-1018-aws      ] [0.0.0.0        ] [2024-11-10T19:09:10,367096+00:00]
```

Could it be a regexp problem given the coincidentally identical minor
versions (`1018`) of these kernels?

Title:
  'last' command output is wrong

Status in util-linux package in Ubuntu:
  Confirmed

Bug description:
  Xubuntu 15.10
  util-linux 2.26.2-6ubuntu3

  The output of 'last reboot' is wrong. It says 'reboot' is 'still
  running' when it shouldn't be, and then arbitrarily 'reboot' stops
  running, causing strange lines such as:

  reboot   system boot  4.2.0-30-generic Tue Mar 22 21:25 - 22:59
  (2+01:33)

  This line shows that 'reboot' was logged in from 9:25pm to 10:59pm on
  the same day, but the total login time was 2 days, 1 hour and 33
  minutes.

  'reboot' can be 'still running' multiple times simultaneously.

  I've attached the results of these commands:

  last reboot
  last -f /var/log/wtmp.1 reboot
  last
  last -f /var/log/wtmp.1
