Upgrade to feisty causes loss of TTYs due to incorrect file mangling

Bug #104038 reported by Trent Lloyd on 2007-04-07
Affects Status Importance Assigned to Milestone
upstart (Ubuntu)

Bug Description

Binary package hint: upstart

I upgraded my machine to feisty and caused loss of TTYs, it mangled the tty1-tty6 files

The last line now reads

 "/sbin/getty 38400 tty2exec /sbin/getty 38400 tty2" (same for each different tty)

Which obviously is wrong, I suspect one of the upgrade scripts may have caused this

Now as a point I cannot remember if this machine was upgraded from dapper, or from edgy, I suspect it may have been dapper which could be the root of the problem, I realise that generally upgrading between releases is not supported but since 6.06 is LTS this may cause a bug when the next LTS comes out so could probably be fixed.

This is also really bad because you lose the TTY in recovery mode as well.

I have also experienced my tty's disappear after an upgrade from edgy, is there a work around ? any info i can provide ?

A workaround: fix the tty files manually. E.g., the last line of /etc/event.d/tty1 reads:

/sbin/getty 38400 tty1exec /sbin/getty 38400 tty1

Change this into

exec /sbin/getty 38400 tty1

Same for the other tty's. Then reboot.

Thanks that's done it

But I'm still interested, which package create these files? How
can I recreate the files, if i lost them.

I tried to reinstall several packages, but none of them creates
a missing ttyx file.

best regards!

Maybe this bug should be moved in their direction

( apt-file search is your friend )

As an experiment (I know it's not supported) I did a Dapper --> Gutsy dist-upgrade yesterday and this problem is still present.

Let me start with that I'm no expert on the installation system, but here's what I've learnt so far:

$dpkg -S tty1
system-services: /etc/event.d/tty1

$dpkg -L system-services

$cat /var/lib/dpkg/info/system-services.postinst
{confirms that /usr/lib/upstart/migrate-inittab.pl does the work}

That means to my mind that the error is very likely happening within migrate-inittab.pl

(Of course it may well be that this was obvious to all involved.)

I'll do some Perl RTFM-ing and see what I learn.

Scott, in your Dapper --> Gutsy upgrade, could you please attach a copy of one of the tty{x} files. I'm trying to figure out which path it takes through the code and I really don't want to install Dapper, then migrate to Gutsy just to find out :)

Scott , I lost my consoles eht upgrading to gutsy but I noticed the "getty"s are running and my problem was the framebuffer.
I have and Intel 810 video board.

run a "pidof getty" or try to "cat things > /dev/tty1" just to be sure.

Experienced the same here on a upgrade from feisty to gutsy.
I had to delete vga=0x317 from my menu.lst and booting without any vga=* option.
Now my ttys are visible again, but I'd like to have them back in 1024x768 (as I have been using them sind dapper) and not in 640x480 (or 800x640) as they are now.

I've encountered this as well, This is the third annoying bug I've discovered after the gutsy upgrade. I fixed this manually.

Same problem here.

I'm also using an Intel video board ( Intel Corporation 82915G/GV/910GL Integrated Graphics Controller (rev 04))

If you want I can attach all the files you need to resolve this bug (I'll maintain my system as it is for the next days).

I'm sending my tty1 file.

If you need more files, I'll be glad to send them too.
