Public bug reported:
Binary package hint: update-manager
As this is a message bug only, I think it is a waste of everyone's time
to append logs. So I did not.
I wanted to upgrade an old laptop with a non-working keyboard to the
release candidate of 9.10. It is running 9.04 with LXDE desktop now. It
is a "play machine" that I use for testing. Ideal for running a realease
candidate. Because of the non-working keyboard, I usually connect
through SSH or XDMCP. Both ways work great.
But when I wanted to upgrade the 9.10 RC, it would not.
I typed over an SSH connection:
sudo update-manager -d
This worked, showed the graphical client (I forward X) and gave me the option
to install 9.10, warned that it was not stable yet, and I acknowledged. The
upgrade started, but immediately stopped with a dialog:
"You are running the upgrade over a remote ssh connection with a
frontend that does not support this. The upgrade will abort now. Please
try without ssh."
This is extremely unhelpful. "try without ssh" is almost never an option
for people who use an SSH connection to upgrade a machine, be it a
virtual, a remote server or a server lacking even the hardware to be a
full desktop.
What I expect from such messages is not to block the user, but to guide
the user. The message suggests that there are frontends that DO support
SSH, but it suggests none of them and even does not give any pointer to
some documentation that can help.
I tried "sudo apt-get dist-upgrade", "sudo apt-get dist-upgrade -t
9.10", "sudo aptitude full-upgrade" and "sudo aptitude full-upgrade -t
9.10" with no success either. These ways just do not recognise that
there is a release coming (probably becaused it is not released as
stable yet).
I am upgrading the machine now over XDMCP, which works so far.
Personally, I think this is a lot trickier than doing it over SSH with
X.
But I want to request a more helpful message so the user is guided
toward a solution instead of stopped by the problem. Note that I am not
filing this bug because I think that "update-manager -d" should support
SSH. I cannot jugde that.
Version info ('lsb_release -rd'):
Description: Ubuntu 9.04
Release: 9.04
The version of update-manager is a bit tricky because the upgrade already
started. I get the following output:
$ apt-cache policy update-manager
update-manager:
Installed: 1:0.111.9
Candidate: 1:0.126.6
Version table:
1:0.126.6 0
500 http://us.archive.ubuntu.com karmic/main Packages
*** 1:0.111.9 0
100 /var/lib/dpkg/status
But I started with the stable, (not "proposed") version for 9.10 at 29
october 2009
