Tried to install into a GUID partition table, but failed

[sudodus]

*****

After some more testing, I found that there was some cruft in my persistent live system. I wiped the casper-rw partitions's upper directory except the home subdirectory, and things started to work again in Lubuntu daily :-)

The cruft must be leftover from previous daily editions of Xenial. Sorry for spamming Launchpad with this bug report.

*****

During iso testing I tried to install Lubuntu i386 from the desktop iso file into a GUID partition table, but ubiquity failed and prompted me automatically into this bug report.

-----
I should add that before the crash, there was a warning pop up window:

ubi-prepare crashed
ubi-prepare failed with exit code 10. Further information ... If you do not, your installation may fail entirely or may be broken.

This bug affects also installing from the Lubuntu Xenial desktop i386 iso file to the whole drive (and letting it create an MSDOS partition table on a drive without a partition table), reported as #1530461

[sudodus (nio-wiklund)]

This bug affects also installing from the Lubuntu Xenial desktop i386 iso file to the whole drive (when there is an MSDOS partition table on the target drive).

The installer crashes, when it tells us that it is 'searching the mirror' (in Swedish 'Söker igenom spegeln')

[sudodus (nio-wiklund)]

More information:

- I tried with the same GUID partition table with lubuntu-xenial-desktop-i386_2015-11-24.iso, and it worked.

- I tried to install in English locale (instead of Swedish, which is my native language), and it worked with the daily iso file.

So I'm starting to suspect that there is a problem with the Swedish mirror or the installer's management of the mirror.

I'm glad you found the problem. I will close the bug report then ( you could as well ).

I'm having the exact same issue with customizing Ubuntu's Live CD. sudodus could you let us know what the "cruft" was that you removed to get past this install error?

Many thanks

@Areeb Yasir,

When booted live-only, I wiped the casper-rw partitions's upper directory except the home subdirectory, and things started to work again in Lubuntu daily :-)

I don't know exactly what was causing the problem, but this action solved it. (But we do not know if you have the same problem even if the symptoms look the same.)
