Same here. No longer a problem after 4/18 and 4/19 daily installs.

I tested 'Install Lubuntu' with the current daily iso file

bionic-desktop-amd64.iso (dated April 20)

in my Toshiba laptop

http://www.toshiba.se/laptops/satellite-pro/c850/satellite-pro-c850-19w/

The installer worked all the way (I used 'Something else' and installed
into an old partition.)

-o-

At the end I had to reboot with SysRq REISUB, but that is another
problem (I think a race condition, that was gone for some year, but
reappeared during the development of Bionic).

I tried to reproduce this a couple of days ago with a current daily in
order to debug it, and couldn't; furthermore, some developers who'd
previously been able to reproduce this bug reported that it was now
working fine for them.  This is somewhat unsatisfactory since we don't
know exactly what made the bug go away; but can anyone still reproduce
this with a current daily build (20180418 or newer) of Lubuntu bionic?

@Steve:

Just to add my "color commentary" . . . non-technical experience . . . in
my install of Lubuntu 18 . . . I got the "crash report" when it got to
around the grub-install . . . and the installer quit . . . but, because I
was multi-booting I already had a grub install and on reboot the grub
window opened and the Lubuntu choice was up top . . . and the Lubuntu
system booted up . . . .  This was after the bug report process, etc.

In comparison, I did a U-MATE 18 install a few days after the Lu install .
. . and in U-MATE no errors or crash reports happened in the install, but
on reboot the log in window loads, but putting my password in, just cycles
to a black screen and then back to the log in window . . . .  I'm thinking
there is something in "the installer" that doesn't seem to be getting
"everything" installed . . . ??  In the U-MATE I can log into a TTY and run
update/upgrade . . . think I've done 4 installs on it by now . . . problem
persists . . . .  The "connection"??  Both are 18.04 distros . . . .

2018-04-05 Thread Steve Langasek
It appears the following one-liner patch fixes the permissions problem
in Lubuntu, which is caused by /usr/share/ubiquity/plugininstall.py
being called without elevated privileges.

=== modified file 'ubiquity/filteredcommand.py'
--- ubiquity/filteredcommand.py 2013-02-19 11:33:07 +

 ret = subprocess.call(self.command, preexec_fn=subprocess_setup)
 if ret != 0:

It is not clear to me if this is correct, or why plugininstall.py is
handled via this code path on Lubuntu when it evidently is not on other
flavors (or alternatively: why this code is called with privileges
already raised on all other flavors).

Also, just confirmed that when running from the live session, PKEXEC_UID
is not set (which makes sense, we don't execute under pkexec anymore, in
Ubuntu 16.10 and later) and the installer therefore does not drop
privileges.  So it's altogether reasonable that we don't see any
permissions problems in this install path.

The part that doesn't make sense is why 'Install Lubuntu' has
permissions errors when 'Install Ubuntu' does not.

[Bug 1754174] Re: [Lubuntu] "Install Lubuntu" fails with several commands not found and permission denied

2018-04-05 Thread Steve Langasek
I don't understand why this bug is happening.  Context:
- when run from the live session by clicking on the icon, ubiquity runs under 
sudo and runs entirely as root.  this succeeds.
- when run from the "Install Ubuntu" option in the splash screen, ubiquity 
starts as root with PKEXEC_UID set in the environment telling it the uid to 
drop privileges to; and drops privileges to run as non-root most of the time.
- there is code in ubiquity which is supposed to raise privileges back to root 
before calling any operations that require root.
- the "Install Ubuntu" option works from both Ubuntu 18.04 beta2 and from 
Lubuntu 17.10.1.  Only in Lubuntu 18.04 beta2 is it broken.
- several of the commands which are failing in the logs on Lubuntu due to 
permissions are operations that can only be run via 'chroot' which is a 
privileged operation - so the chroot succeeds, and then afterwards the commands 
lack permissions to operate on the target filesystem?!
- none of the changes to the ubiquity codebase since 17.10 seem to be relevant.
- the code around the point at which the install fails - basically when trying 
to run the first installer plugin (the language plugin) via 
scripts/plugininstall.py - doesn't include any privilege-handling code.  So 
there seems to be an assumption that this code is running as root already.  
Clearly this assumption proves invalid, but I'm unclear where this is supposed 
to be happening.

Okay, so the inability to find lvm2 and python2 commands seems like a
red herring (should probably be cleaned up for nicer logs, but probably
not the issue here) as they also show up in a successful log.  For some
reason, though, it looks like we're dropping privs and can't do some
things as root that we should be doing.

Testing on bare metal in my Toshiba laptop

http://www.toshiba.se/laptops/satellite-pro/c850/satellite-pro-c850-19w/

I can install Lubuntu via a USB live system cloned from the current
bionic-desktop-amd64.iso file, if I select 'Try Lubuntu'.

But the installer fails, if I select 'Install Lubuntu' (go directly to
the installer). I was kicked of the installer, and prompted to create a
bug report, which I did not. Instead I selected 'affects me too' here.

So this bug does not only affect testing in virtual machines, but also
bare metal in a computer that usually works well with Ubuntu based
operating systems.

[Bug 1754174] Re: [Lubuntu] "Install Lubuntu" fails with several commands not found and permission denied

2018-03-10 Thread Walter Lapchynski
Adam, I'm curious about your Python statement. This only fails when
running Ubiquity directly from GRUB. Loading the live system and then
running Ubiquity works fine. Also, Ubiquity fails to fail for any other
flavours.

Things start going south in syslog here:

Mar  7 21:40:40 lubuntu ubiquity[1244]: switched to page partman
Mar  7 21:40:44 lubuntu ubiquity: /bin/autopartition: 292: /bin/autopartition:
Mar  7 21:40:44 lubuntu ubiquity: pvs: not found
Mar  7 21:40:44 lubuntu ubiquity: 
Mar  7 21:40:47 lubuntu ubiquity[1244]: debconffilter_done: ubi-partman 
(current: ubi-partman)
Mar  7 21:40:47 lubuntu ubiquity[1244]: Step_before = stepPartAsk

On a successful install from the live system we find a little bit
different behavior:

Mar 11 01:58:43 lubuntu ubiquity[2161]: switched to page partman
Mar 11 01:58:55 lubuntu ubiquity[2161]: debconffilter_done: ubi-partman 
(current: ubi-partman)
Mar 11 01:58:55 lubuntu ubiquity[2161]: Step_before = stepPartAsk

Noting that /bin/autopartition is a script, I went looking for line 292,
but it wasn't there. It does, however source several other scripts in
/lib/partman/lib. Looking for only files with a line number 292 that
includes "pvs" in it, I found:

lib/lvm-base.sh:if $(pvs --noheadings --nosuffix -o pv_name |
grep -q "$device"); then

Seems like pvs is a variable created from enumerating the partman
devices and looking for ones with lvm method.

I'm not sure what this all means yet, but this sure is weird.

2018-03-09 Thread Adam Conrad
Reproduced in kvm/qemu by booting to the installer from the boot menu.
Can't reproduce by booting to the desktop first and clicking the install
icon.

The first obvious bug (assumption that py2 exists in the target when it
doesn't) is glaringly obvious in the code.  Not sure yet how that would
