Title:
Using an ipv6 address as preseed file location results in an installer
error
Status in Ubuntu on IBM z Systems:
New
Status in preseed package in Ubuntu:
New
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
