[Bug 1660633] Re: /usr/bin/ucfr: line ... : [: : integer expression expected

[Andy]

Related commentary #28 from Ask thread:
[....]
"This all seems to be related to http://www.grymoire.com/unix/CshTop10.txt (search for 'Illegal variable name.')

Still there is the open question, why you get different results between
"grep -E ..." and "egrep ..."

What I can suggest:
1. avoid tcsh and csh when updating your system, because ucfr might fail
2. suggest that ucfr avoids the string $" because grep will fail if tcsh or csh is used. (this should go into the bug report)"

Title:
  /usr/bin/ucfr: line ... : [: : integer expression expected

Status in ucf package in Ubuntu:
  New

Bug description:
  I've had a reoccurring issue: https://ubuntuforums.org/showthread.php?t=2350682
  Running: ucf_3.0036_all.deb

  http://askubuntu.com/questions/875415/usr-bin-ucfr-errors-integer-expression-expected
  http://serverfault.com/questions/827873/grub-pc-update-fail-dev-sda-ext2-doesnt-support-embedding

  I don't know why ucfr is erroring out but the accumulated errors are
  now enough to stall priority packages which I feel hamstrung about.
  I've reinstalled the ucf package and danced around the issue enough.

  Any maintainers have a shot in the dark for why this would be
  happening?
