Subject: Kubuntu upstart stagnates after failed attempt to upgrade from Jaunty to Karmic.<br>To: Kubuntu Help and User Discussions <<a href="mailto:kubuntu-users@lists.ubuntu.com">kubuntu-users@lists.ubuntu.com</a>><br>
<br><br>
<p style="margin-bottom: 0cm;">Hello everybody<br>
</p>
<p style="margin-bottom: 0cm;">Yesterday (Fri. 6 November 09) I
started an attempt to upgrade my laptop from Kubuntu 9.04 to 9.10.
However, today it became clear that this attempt failed. Moreover: at
the laptop as it is now, it is simply not possible any more to start
Kubuntu at all. That's why, I would like to evaluate with you what
exactly went wrong and which mistakes I need to avoid: ….</p>
<p style="margin-bottom: 0cm;">* ….when carrying out a fresh
'install from scratch' from a Kubuntu 9.10 CD at the laptop</p>
<p style="margin-bottom: 0cm;">* ….when carrying out an upgrade from
Kubuntu 9.04 to 9.10 at my desktop.
</p>
<p style="margin-bottom: 0cm;">
</p>
<p style="margin-bottom: 0cm;">In principle, I am perfectly happy to
do a fresh 'install from scratch' at my laptop with an image CD of
Kubuntu 9.10. From all the files, I have back ups at an external HD
and a desktop. So, I would not loose any data by reformatting the
laptop HD during such an installation procedure. On the other hand, I
still would prefer an upgrade instead of an 'install from scratch'
at my desktop CD.
</p>
<p style="margin-bottom: 0cm;">
</p>
<p style="margin-bottom: 0cm;">At the laptop in it's present state,
the upstart procedure simply gets stuck. Immediately after starting
or restarting the laptop as it is now, the following happens.</p>
<p style="margin-bottom: 0cm;">
</p>
<p style="margin-bottom: 0cm;">In the beginning, I do not see any
initial screen, mentioning the possibilties to run a 'memtest' , a
terminal or Kubuntu in a 'normal' or 'safe' mode.
</p>
<p style="margin-bottom: 0cm;">
</p>
<p style="margin-bottom: 0cm;">However, the upstart procedure still
goes on, till I see a few failure reports.
</p>
<p style="margin-bottom: 0cm;">
</p>
<p style="margin-bottom: 0cm;">Soon after the Kubuntu logo shows up,
a first terminal failure report tells the following:</p>
<p style="margin-bottom: 0cm;">
</p>
<p style="margin-bottom: 0cm;">“(...)
</p>
<p style="margin-bottom: 0cm;">Mountall : symbol lookup error:
mountall: undefined symbol: udev_monitor_dd_match_substystem_devtype</p>
<p style="margin-bottom: 0cm;">init: mountall main process (687)
terminated with status 127
</p>
<p style="margin-bottom: 0cm;">(...)”</p>
<p style="margin-bottom: 0cm;">
</p>
<p style="margin-bottom: 0cm;">Than, I get 25 to 50 failure reports
who look quite similar, but whose codes and figures slightly differ
from one another. Below I mention the last three reports amongst
them:</p>
<p style="margin-bottom: 0cm;">
</p>
<p style="margin-bottom: 0cm;">“ (…)</p>
<p style="margin-bottom: 0cm;"><span style="text-decoration: none;">[
</span><u>59.81</u>7955] Corrupted low memory at <u>c004e</u>98
(<u>4e</u>09 <u>phys</u>) = fffff4906</p>
<p style="margin-bottom: 0cm;">[ <u>59.81</u>8013] Corrupted low
memory at <u>c004e</u>98 (<u>4e</u>9c <u>phys</u>) = aa666601</p>
<p style="margin-bottom: 0cm;">[ <u>59.81</u>8124] Corrupted low
memory at <u>c004ea</u>0 (<u>4e</u>a0 <u>phys</u>) = 0000cc00</p>
<p style="margin-bottom: 0cm;">(….) “</p>
<p style="margin-bottom: 0cm;"><br>
</p>
<p style="margin-bottom: 0cm;">Immediately after the last of the three
lines above, the following report comes:</p>
<p style="margin-bottom: 0cm;">“(…)
</p>
<p style="margin-bottom: 0cm;">[ 59.818124] Memory corruption
detected in low memory</p>
<p style="margin-bottom: 0cm;">(...)”</p>
<p style="margin-bottom: 0cm;"><br>
</p>
<p style="margin-bottom: 0cm;">After this, the upstart procedure
stagnates immediately.
</p>
<p style="margin-bottom: 0cm;">Now, every attempt to start Kubuntu at
the laptop ends up in the results summarised above – but still the
figures and codes slightly differ; only the <u>underlined</u><span style="text-decoration: none;">
parts of them are the same. </span>
</p>
<p style="margin-bottom: 0cm;"><br>
</p>
<p style="margin-bottom: 0cm;">Of course, I have been trying to
evaluate what could have gone wrong in this process. The problem
could be related to the unreliable WIFI signal I am using now. It
could also have to do something with the laptop itself.
</p>
<p style="margin-bottom: 0cm;">The WIFI signal I point at, comes from
an 'unencrypted network' which is not constantly available. If the
signal is there, some internet pages are being opened quite slowly.
Downloading files take much more time compared to a steady, wired
connection. Sometimes, downloading processes are simply being
interrupted because of the WIFI signal fading away totally. The
upgrade in combination with this WIFI connection was quite slow
compared to a similar process in combination with a wired or more
strong WIFI connection. Often, this connection is simply fading away
or being interrupted. I needed to wait a bit before I could send this
message to the list.
</p>
<p style="margin-bottom: 0cm;">
</p>
<p style="margin-bottom: 0cm;">In about one week I will have again a
more reliable, own internet connection. If the problem would only
have to do with this connection issue, I simply could wait for that.
</p>
<p style="margin-bottom: 0cm;">However, I am wondering whether the
problem also is related with the laptop itself: if I do not touch it
for more than about 5 minutes, it automatically comes into a kind of
hibernating mode. After some hours, the laptop totally shuts down,
unless I reactivate it by touching one or more keyboard buttons.
</p>
<p style="margin-bottom: 0cm;">
</p>
<p style="margin-bottom: 0cm;">Could you please let me know how I
could avoid similar problems when trying again to upgrade my desktop
and to carry out a fresh installation at the laptop? I would
appreciate your feedback.</p>
<p style="margin-bottom: 0cm;">

<p style="margin-bottom: 0cm;">Respectfully yours,</p>
<p style="margin-bottom: 0cm;">Bas.
