I have installed Oracle 10g Express edition in Ubuntu 10.10 and it doesn't show or ask to give my password during installation.

When I click on "start database" it gave the warning "Operation failed, abhi is not a member of 'dba' group." and when clink on "Run SQL command line" it shows /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/nls_lang.sh: 114: [[: not found

When I click on "GOTO Database home page", it opens Mozilla's "Ubuntu Google search page".

Can anyone help me get my Oracle to work or tell me how to remove that because it is also not getting removed.
I tried all the commands that are given as suggestions by Ubuntu.

Please help me because I don't want to format my Ubuntu.



/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/nls_lang.sh: 114: [[: not found

The solution is to simply edit it (as root) and remove a pair of square brackets on lines #108 and #110.


sudo -H gedit /usr/lib/oracle/xe/app/oracle/product/10.2.0/server/bin/nls_lang.sh

Scroll down until you find this:

if [[ -n "$LC_ALL" ]]; then  
elif [[ -n "$LANG" ]]; then  

Then change it to this (remove a pair of brackets):

if [ -n "$LC_ALL" ]; then  
elif [ -n "$LANG" ]; then  

Then click SAVE. Now try this command again to set your environment variables:


Nothing appears to happen when you do it but, it auto-sets your variables. DONE!

P.D :

About the error ....

you may get an nls_lang error as follows when you try to export the environment variables.


ubuntu uses a BASH linux shell. Now open “nls_lang.sh” with a text editor and set the correct shell parameter in the first line of the script.

see step 5. open nls_lang.sh.


The nls_lang.sh script has the /bin/sh shebang.

By default Ubuntu links /bin/sh to /bin/dash with can cause somme issues. To fix this link /bin/sh to /bin/bash with is more compatible with /bin/sh:

ln -sf /bin/bash /bin/sh
