"bash: [: : integer expression expected" when launching debian shell

[gerroon]

Hi

I just installed the latest from the release page and I am getting bunch of PATH errors

/usr/local/sbin /usr/sbin /sbin

and ldconfig are all missing

thanks

[eighthave]

where do you see that error?

[gerroon]

when I try apt-get install somepackage. This debian img was working fine ;(

My /etc/profile looks fine as far as I can tell

[eighthave]

Are you doing this in Android Terminal Emulator? An ssh session? An adb shell session?

[gerroon]

I did run terminal (after starting debian) Opening terminal form lildebi types bunch of jumble chars on the terminal on my 4.4.4 so I do manually.

su /debian/shell :#/ apt-get install someapp

[eighthave]

Is there any other error? For a workaround, you can do export PATH=/usr/sbin:/sbin:$PATH

[gerroon]

/debian/shell gives me "bash: [: : integer expression expected" same with sh

There is also "tcgetattr: Invalid argument" in Lildebi.

[eighthave]

This looks like the same issue as #116, I guess it is not quite fixed.

[gerroon]

@eighthave This is weird realy, I do not remember having this on previous versions. It seemed to popup in recent versions

[eighthave]

Ok, I was getting this issue too. I looked at my device, and it was in a quasi mounted state. /data/debian was mounted, but none of the bind mounts were, like /data/debian/proc, etc. Rebooting my device got the mounting working properly, after a manual e3fsck. And now /debian/shell no longer tells me "bash: [: : integer expression expected"

[gerroon]

@eighthave That did not help me whatsoever. I think that this issue has been introduced recenty.

I restarted, started debian and started terminal and I get bunch of mambo jumbo including "anproject.lildeb/app_bin:$PATH chroot /debian /bin/bash -l" @=^sk48 : : integer expression expected"

bear in mind this is happening in android termianl not debian chroot terminal.

Then there is no /debian. I have to stop it and restart debian a second time to get the /debian showup so I can run the shell

[eighthave]

As you can see from all those commits, I was working on this issue. I fixed up /debian/shell a lot. You can try it now by getting it from the commits above, or here:

#!/system/bin/sh 

export TERM=linux
export HOSTNAME=debian
export HOME=/root
export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/system/xbin:/system/bin
app_bin=/data/data/info.guardianproject.lildebi/app_bin
export USER=root

username=`$app_bin/whoami`
id=`$app_bin/id -u`
if [ "$id" -eq 0 ]; then
# try using the chroot included in LilDebi, otherwise fail over to a possible system one
    PATH=$app_bin SHELL=/bin/bash $app_bin/chroot /debian /bin/bash --login -i \
        || chroot /debian /bin/bash --login -i
elif grep "^${username}:" /debian/etc/passwd > /dev/null; then
    su -c "PATH=$app_bin SHELL=/bin/sh TERMINFO=/lib/terminfo USER=$username \
             $app_bin/chroot /debian /bin/su $username --login"
else
    su -c "HOME=/root PATH=$app_bin SHELL=/bin/bash TERMINFO=/lib/terminfo \
             $app_bin/chroot /debian /bin/bash --login -i"
fi

[SDkie]

@gerroon : which version of lildebi you are using ?

[gerroon]

I do not think that the latest version fixed my issue. I do not understand this ;( I nevber had these path issues prior to the latest versions

[eighthave]

0.5.2 didn't change anything? Can you try a few things and report back:

Run "Open Terminal..."

Run in an adb session:

adb shell
/debian/shell

Run as root in an adb session:

adb shell
su
/debian/shell

Run in an Terminal Emulator:

/debian/shell

Run as root in an Terminal Emulator:

su
/debian/shell

[Canar]

I encounter this problem also. The fix is trivial.

In /etc/profile,

if [ "`id -u`" -eq 0 ]; then

id -u is returning nothing, not even a zero. Don't know why, but that's what's happening. Therefore, when you simply add a zero before the double quote, like so:

if [ 0"`id -u`" -eq 0 ]; then

The problem goes away and you can enjoy your Debian like usual.

[eighthave]

The problem happens when id -u from Android is run, rather than id -u from Debian. id -u does the right thing on some Android ROMs, but not all. /debian/shell sets the PATH before to make sure the Debian id -u is used, but it seems to fail sometimes. That's the part that I don't understand.

[Marietto2008]

Hello. I have installed Lil Debi on my nexus 10 and I have the same problem. Inside the android terminal I have no /debian/shell file. I would like to edit the file /etc/profile/ but I don't know how to do since I can't install new packages,I can't use the ee or the nano file editor.... what can i do ?

[Canar]

/usr/bin/nano /etc/profile should work

[Marietto2008]

do you know if there is a way to increase the storage space of my nexus 10 in some way ? because I've tried to install Lil' debi but I've not been able to complete the procedure since I have not enough space. My opinion is to change the internal structure of lil' debi so that it can be installed in one external storage. But how ? and which kind of storage can I use ? thanks.

I have the same problem on CM11 Nexus7 and Xperia M also on CM11. I found out that busybox from inside chroot environment doesn't work.

root@localhost:/data/data/info.guardianproject.lildebi/app_bin# ./busybox [1] Segmentation fault ./busybox

and just after starting user shell line "if [ "$id" -eq 0 ]; then" in /etc/profile is issued and doesn't return awaited result. Replacing busybox in $app_bin with working version does made environment working. I have used this one: http://www.busybox.net/downloads/binaries/latest/busybox-armv7l If you don't want to replace busybox - it is enough to put line PATH=/usr/bin before mentioned line or use full path of id i.e /usr/bin/id.

[eighthave]

Something odd is going on here. LilDebi's embedded busybox works fine for me in both the adb shell and when I'm in the Debian chroot.

@jkk88 could you try one thing to get the included busybox working:

adb shell
su
/debian/shell
cd /data/data/info.guardianproject.lildebi/app_bin
echo $LD_LIBRARY_PATH
export LD_LIBRARY_PATH=/vendor/lib:/system/lib
./busybox

[jkk88]

Hans,

here is output:

Ok, guess that hunch was wrong... I'm stumped as to why this might happen. Does busybox run under the plain Android shell, i.e.:

adb shell
su
cd /data/data/info.guardianproject.lildebi/app_bin
./busybox ls

Or maybe it needs to use the full path, i.e.

adb shell
su
/data/data/info.guardianproject.lildebi/app_bin/busybox ls

I have checked launch script $app_bin/shell and probably all occurence of PATH=$app_bin should be removed.

[eighthave]

So I found a way to make /debian/shell work the old way, requiring root beforehand, on devices that are affected by this issue. On devices where id -u gives the right info, then /debian/shell can be run as non-root.

[SDkie]

When I click on 'Open Terminal' while testing lildebi on cm-11

[eighthave]

is that new behavior with this new commit? It is odd behavior for sure, do you know if it is breaking anything?

[SDkie]

@eighthave : I tried with V0.5.4 from F-Droid, and I also tried building lildebi from source. Its giving me same issue. I tested it on my new Nexus-5, not sure when this is broken.

[eighthave]

@SDkie which issue? the export COLUMNS LINES issue, or "bash: [: : integer expression expected" ?

[SDkie]

When I run app_bin/shell manually from terminal then I am getting "bash: [: : integer expression expected" which is I guess because of "--login" parameter.

But when I click on "Open terminal" I see weird symbols "0;60R", and I am not inside the Debian shell as expected.

The export COLUMNS LINES is done by the default android shell. Nothing to do with lildebi.

I have noticed later that $app_bin/busybox don't contain applet env so if used such construction busybox should be recompiled. For non root user using Term app there is accessible at least /data/data/jackpal.androidterm/app_HOME/bin alongside sytem path which can be added to search path for busybox Maybe to make it cleaner all utilities should be written with full path for ex. $BUSYBOX grep and on beginning of script define configurable full path of busybox

[adamjhogan]

Compiling busybox with env could help us to dynamically unset LD_PRELOAD only when needed. (https://gist.github.com/godlessfather/1436d5fa5ce9e6f48d8b is my hammerhead's env for reference)

[adamjhogan]

@SDkie CM11 on Hummingbird

[jkk88]

This is working on cm11 very well - using cm11 builtin busybox. Busybox in lildebi need to be recompiled with env applet. You can also try one from here: http://forum.xda-developers.com/showthread.php?t=1929852 and then correct path in line beginning with BUSYBOX=

An easy workaroung for this problem (wrong path and "[: : integer expression expected " error ) is to use su instead of bash when chrooting, as

chroot /debian /bin/su -l

Thanks for the tip. Have you tested it on Android or LilDebi? I thought that bash --login -i was supposed to do the same kind of thing.

I observe that '--login' parameter giving that error.

@eighthave I tested the commond on android (4.4 rooted)

chroot /debian /bin/su -l

I guest it would be easy to change the command which is started by the terminal emulator
