[Bug 1818285] Re: [disco desktop] Installation fails with parted_server: No data in infifo. parted_server: Line 2387. CRITICAL ERROR!!! EXITING.

[Jean-Baptiste Lallement]

I'm reassigning to partman-base.

If I replace /bin/parted_server from Ubiquity 19.04.6 by the version of
the binary package of 19.04.5 it fixes the issue. According to the d-i
manifest and the source diff only user-setup has been updated in .6 but
the following files are different:

ubiquity_19.04.5_amd64/bin/blockdev-wipe
ubiquity_19.04.5_amd64/bin/log-output
ubiquity_19.04.5_amd64/bin/mapdevfs
ubiquity_19.04.5_amd64/bin/parted_devices
ubiquity_19.04.5_amd64/bin/parted_server

Bug description:
  Ubuntu Desktop Disco amd64

  Last known good version: ubiquity 19.04.5

  Automated preseeded tests of Ubuntu Desktop Disco, started failing on
  Feb. 4th with this error in partman log:

  /bin/partman: *******************************************************
  /lib/partman/init.d/30parted: *******************************************************
  parted_server: ======= Starting the server
  parted_server: main_loop: iteration 1
  parted_server: Opening infifo
  /lib/partman/init.d/30parted: IN: OPEN =dev=vda /dev/vda
  parted_server: No data in infifo.
  parted_server: Line 2387. CRITICAL ERROR!!!  EXITING.

  /var/log/ and journal attached to this report.

  Maybe it's a coincidence but it started after the upload of partman-
  crypto.

  Manual installation with Ubiquity fails too with the same error.

  Test Case:
  1. Boot to the live session
  2. Launch Ubiquity
  3. Press 'Next' on all the steps keeping the default

  Actual Result:
  You cannot go beyond the 'Updates and Other software' page.
