Comment 5 for bug 1373365

3rd test:

Trying again, this time again from a live session , and using another partition formatted by gparted: This time it created a working Lubuntu Utopic system :-)

So my conclusion so far is that either there are problems installing from the live session when several other programs has been run (testing that the live session works), or that first particular file system made by gparted was bad. The Ubiquity installer has been very sensitive during several versions, and installation should be done at once, not after running several other programs, particularly with low RAM.

With 4 GB RAM (in this test), there should not be a problem with too low RAM, but maybe zRAM was crowded and caused problems (zRAM is used in Lubuntu's live session).

4th test:

Tried again, this time without swap and zRAM, but running some programs before starting Ubiquity and setting up the root partition for re-formatting. The same thing happened as the first time (or very similar). Stuck at 'Identifying file system...'.

I had htop on, and it showed RAM usage approx 300 MB (of a total of 4 GB) so the computer was not running out of memory.

Just after leaving the partitioning screen the system complained that it could not shut off the swap. But I had already done it manually (including zRAM).

It seems that Ubiquity is happy only when it is allowed to run first (not after other programs have been running).
