[Bug 1679652] Re: Using an ipv6 address as preseed file location results in an installer error

[Dimitri John Ledkov]

Looking at the syslog, the kernel commandline as passed to the kernel is
invalid:

Apr  4 10:19:26 kernel: [    0.406602] setup.1a06a7: Linux is running as a z/VM guest operating system in 64-bit mode

clearly the URL should be http://[fd00:10:100::86:49]/ubuntu/mroesch/zesty.preseed, not ^G.

Currently testing qemu/kvm

Title:
  Using an ipv6 address as preseed file location results in an installer
  error

Status in Ubuntu on IBM z Systems:
  Confirmed
Status in preseed package in Ubuntu:
  Confirmed

Bug description:
  Installer version: 20101020ubuntu500
  Kernel: 4.10.0-14

  Description/Reproduction:
  Trying to perform an IPv6-based installation using a preseed file that should be retrieved from an IPv6 URL  results in this installer error:
  "The file needed for preconfiguration could not be retrieved from
  http://xxxxxxxxxxxxxxxx:10:100::86:49/ubuntu/name/zesty.preseed
  The installation will proceed in non-automated mode."

  The parameter in the parmfile looks like this:

  preseed/url=http://[xxxxxxxxxxxxxx:10:100::86:49]/ubuntu/name/zesty.preseed

  I also tried escaping the square brackets, but that also doesn't work

  In syslog you see the following error:

  Apr  4 10:22:22 main-menu[465]: (process:481): expr: warning: '^.*\[[:a-fA-F0-9]*\]': using '^' as the first character
  Apr  4 10:22:22 main-menu[465]: (process:481): of a basic regular expression is not portable; it is ignored
  Apr  4 10:22:22 main-menu[465]: (process:481): http://xxxxxxxxxxxxxxxx:10:100::86:49^G/ubuntu/name/zesty.preseed: Bad port number.

  We had found a similar bug in Ubuntu 16.04
  (https://bugzilla.linux.ibm.com/show_bug.cgi?id=137452 , Launchpad Bug
  LP1547629)

  I have attached the logs.
