Spent most of yesterday on upgrade from 10.04 to 12.04, on Acer Aspire One A110AB (Intel Atom processor 1.6GHz, 16gb ssd, 1gb RAM, no optical drive). Had about 2.3gb of free space to begin but cleared more on prompts during upgrade. Also got numerous illegible dialogue boxes of squares-for-letters, but 'OK'ed them, I think, on reading that they were an irrelevant Evolution artefact. For the last 12 hours the process has been frozen In stage 'Installing the Upgrades', with just 27min left, and the last progress item reading 'Installed mousetweeks'. The last few lines on the terminal read: Setting up modemmanager (ubuntu 0.5.2.0-0ubuntu2) ... Installing new version of config file /etc/dBus-1/system.d/org.freedesktop.ModemManager.conf ... initctl: Method "Get" with signature "ss" on interface "org.freedesktop.DBus.Properties" doesn't exist ...
initctl:dbus_error.c:69: Unhandled error from nih_dbus_error_raise: Method "Get" with signature "ss" on interface "org.freedesktop.DBus.Properties" doesn't exist
At the moment the system appears to be more or less working -- I'm sending this through Chromium on it and I can look for files and edit documents in LibreOffice. 'Help and Support' doesn't open anything. My space is at 1.2gb. USB drives are not recognised. I'm not Linux-technical especially but can follow instruction on the terminal. Help, please? Thanks! Harry PS I note that the (well hidden) advice for the likes of me was to wait until July. However, given the hype about 12.04 and the widespread raves about its readiness and stability, I thought this was safe enough. I would rather not wipe my computer for a fresh install.
EDIT: I bit the bullet and restarted the netbook, and found I'm now the proud owner of a Unity desktop and an otherwise semi-functional system. Update manager says it can only do a 'Partial Upgrade' and when it tries it again finds itself blocked by another process.
