32-Bit Chroot How-To

[draven]

In order to get FF32 and Flash working I had to manually install Flash by copying the files to the plguins dir. Then using synaptic32 I installed libXmu-dev.


EDIT:

Now I'm having a problem where I can't close any TABS in FF. If I hit the red X, use right-click // close-tab it just won't close. I can open new ones though. It works in the 64bit FF but not the chroot 32bit. It also reports no errors in the console.

Heh. Just a brief post, but if you have made the chroot and decide you want to get rid of it, it seems taking out the new lines in fstab, doing mount -a and then rm -rf /chroot really isn't the best idea.
I ended up wiping my /home, /tmp, /dev etc.
After that I just went su, rm -rf /, because I always wanted to try that, but yeah.

Ooops. >.<.

hiya, ran through your HOWTO and it seems to have worked! cheers! i did get this error when running sudo mount -a though:
[mntent]: warning: no final newline at the end of /etc/fstab

can anyone tell me what this means?

also, im trying to run stuff with wine but im getting an error that looks like this:

paul@ubuntu:~$ wine /DATA/stuff/Brain.exe
(breezy) wine /DATA/stuff/Brain.exe
wine: cannot find '/DATA/stuff/Brain.exe'
dchroot: Child exited non-zero.
dchroot: Operation failed.

any ideas? thank you.

I'm guessing its because the file in quest isn't in the 32 bit directory structure

I'm having a related problem - I want to know how I can directly execute a program using wine and chroot, in a single command. The path name of the program I want to wine has spaces in it, but for some reason the "s get stripped out in the process.

[wishyjr]

cheers. yeah, i thought that not long after i'd posted my question.

regarding yours though, about executing stuff directly through chroot, i used this:

sudo ln -s /usr/local/bin/do_dchroot /usr/local/bin/wine

it seems to work, but then again i havent tried it out yet. i can get xwine to run through it though.

I have been in following the how to. I am running Breezy, but still following the Hoary chroot, as someone here recommends to follow word by word unless I know what I am doing. Anyway when I reached the final step of "sudo synaptic32", I get this:

(hoary) synaptic32
bash: synaptic32: command not found
dchroot: Child exited non-zero.
dchroot: Operation failed.

At the step of "sudo apt-get install synaptic", it doesn't seem to work. I got this message:

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = "en_SG:en",
        LC_ALL = (unset),
        LANG = "en_SG.UTF-8"
    are supported and installed on your system.

Any clue?

Thanks

Anyone have a solution for this yet? I am having exactly the same issues.

EDIT:
no idea why but I decided to try changing all 'hoary' references to 'dapper' and it worked fine, and I have FireFox 1.5

I also have this unknown group 'postdrop' error. Upto that point everything went well. Has anyone solved this problem?

I have found a solution to this problem but i'm not sure why something like this happened.

My /var/lib/dpkg/statoverride file is like this:
hplip root 755 /var/run/hplip
----

but if i cat /chroot/var/lib/dpkg/statoverride i get (i have no idea why):
root postdrop 02555 /usr/sbin/postqueue
postfix postdrop 02710 /var/spool/postfix/public
root postdrop 02555 /usr/sbin/postdrop
-------

When i delete the lines that has postdrop postfix groups or users the problem solved.

One alternative might be adding group and user
addgroup postdrop
adduser postfix

I have no idea what will be the impacts, or is it safe to do this, but i could install the synaptic after these edits.

Ok, so I'm having trouble with getting synaptic32 to run in the chrooted environment. I followed this guide step by step, only replacing all instances of "hoary" with "breezy", and when I run the synaptic32 command, it just shows the following:

username@ubuntu:~$ sudo synaptic32
(breezy) synaptic32
bash: synaptic32: command not found
dchroot: Child exited non-zero.
dchroot: Operation failed.

I tried to mount the directories one by one, simlinking them... Nothing worked.

This is a copy of my /etc/fstab file, just in case it's needed:

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
/dev/sda2       /               ext3    defaults,errors=remount-ro 0       1
/dev/sda1       /media/sda1     ntfs    defaults	0       0
/dev/sda6       /media/sda5     vfat    iocharset=utf8,umask=000   0       0

/dev/sdc        /media/usb0     auto    rw,user,noauto  0       0

#dchroot

/proc /chroot/proc proc defaults 0 0
/media/cdrom0 /chroot/media/cdrom0 none bind 0 0
/usr/share/fonts /chroot/usr/share/fonts none bind 0 0

Any ideas?

[Off-topic] P.S: BTW, "iocharset=utf8,umask=000 0 0" doesn't seem to work for my FAT32 partition, since it sets permissions to 555 which doesn't let anyone write to it. I can't chmod nor chown it, not even as root... So what gives? [/Off-topic]

Thanks in advance for any help that you may provide.

my usb-gamepad only works with a generic driver(2 buttons, 2 axis!!!) in chroot, although it works perfect in my normal enviroment. In jscalibrator thc console gives this error message:
Failed to set joystick /dev/js0 correction values: Invalid argument
does anybody know how to fix this?
