package man-db 2.7.6.1-2 failed to install/upgrade: triggers looping, abandoned

[Rick]

did a "sudo ubuntu-driver auto update"
to fix a graphics issue and when I restarted the computer, I now get the Nvidia splash screen
where I did not before, I am directed to the login screen, but when I log in the screen goes black
I bring up a tty using ctrl-alt-f3 and typed startx. the gui starts up but icons and programs downloaded are missing. I got a report that an error had occurred so I authorized submittal of the report. I am unsure if this is a security vulnerablity so I will also submit it as one just in case.

Hi Rick, this auto-submitted bug is for another separate issue on your computer -- triggers looping during package installation.

It'd be best to file a new bug about your trouble logging in. Use

dpkg -l 'nvidia*' | grep '^ii'

to find out which nvidia packages are installed, and use

ubuntu-bug nvidia-....

on whichever version is the newest.

At least I think that's most likely package responsible for your issues.

Thanks

dpkg: cycle found while processing triggers:
 chain of packages whose triggers are or may be responsible:
  desktop-file-utils -> bamfdaemon
 packages' pending triggers which are or may be unresolvable:
  man-db: /usr/share/man
  doc-base: /usr/share/doc-base
  libc-bin: ldconfig
  bamfdaemon: /usr/share/applications
  desktop-file-utils: /usr/share/applications
  mime-support: /usr/share/applications
  gconf2: /usr/share/GConf/gsettings

man-db is only tangentially involved here; I think this must be a dpkg bug.
