[Bug 1313784] Re: File descriptors leaked on lvs invocation

[iGadget]

Glad I found this bugreport. The message got me worried, and I can imagine it will keep on creating the same thought with many more people until it (finally!) gets suppressed.
Just got this on 20.04 today while running apt autoremove:

Generating grub configuration file ...

  File descriptors leaked on lvs invocation

Bug description:
  While upgrading to Kubuntu 14.04 yesterday, I got the following error
  messages over and over again:

  Generating grub configuration file ...^M
  File descriptor 3 (pipe:[4852522]) leaked on vgs invocation. Parent PID 6438: grub-probe^M
  File descriptor 59 (/var/log/dist-upgrade/apt.log) leaked on vgs invocation. Parent PID 6438: grub-probe^M

  
  The file descriptors appeared random, and the "Parent PID" was either /bin/sh, grub-install, grub-probe or /usr/sbin/grub-probe:
  grep leaked ./dist-upgrade/apt-term.log |sed 's/.*Parent PID [0-9]*: //' | sort  | uniq -c
       53 /bin/sh
       72 grub-install
      106 grub-probe
     1484 /usr/sbin/grub-probe
