I have Lubuntu 16.10 and I am trying to install the Elementary OS Openbox theme from this page: https://www.box-look.org/content/show.php/Elementary+OS+Openbox?content=163471

I downloaded the .obt file and tried to install it in Customize Look, but it gave me this error:enter image description here

  • Hello, whats your status? Have you solved your issue? – Samuel Mar 22 '17 at 9:36

The problem with that theme is it doesn't respect the file structure of an Openbox theme, because it should contain a top level directory with the name of the theme.

Hint: You can use file-roller or other archivers to see the contents of an .obt file (it seems to be just a zip file with an obt extension).

Anyway, I couldn't install the theme either using lxappearance (Customize Look). So here's what I did:

1) Open a terminal.

2) Create a directory to contain the files:

mkdir Elementary-openbox

3) Extract the archive files:

unzip -d Elementary-openbox /path/to/163471-elementary-os-05102014.obt

(replace /path/to with an actual path)

4) Move the theme:

mv Elementary-openbox $HOME/.themes

Now the theme should be installed as Elementary-openbox.

Hint: Openbox and GTK themes are installed globally to /usr/share/themes and locally to /home/{username}/.themes. Writing to /usr/share/themes requires root access.

Problems with directory and its permissions

Additionaly, if you have any problems copying the theme files to $HOME/.themes this may be of help:

We will be using a terminal, so open one.

  1. Check that the directory exists:

    stat $HOME/.themes <- this command will complain if a file or dir doesn't exist.

    If it doesn't exist, create it: mkdir $HOME/.themes

  2. If the file does exist, check your permissions:

    myuser@myhost:~/some/path$ ls -al $HOME/.themes
    drwxrwxr-x  8 myuser mygroup 4096 mar  1 02:24 .
    ^           ^   ^       ^      ^   ^   ^   ^   ^
    |           |   |       |      |   |   |   |   |
    col. #1     #2  #3      #4     #5  #6  #7  #8  #9

    Note: We only care about the line for the file whose name is the dot (.), that is the 9th column, which refers to the $HOME/.themes directory.

    2.1. First, verify that you are the directory's owner (given by the third column, 'myuser' in this case), not root, not anyone else. If you are not the owner, change the directory's ownership with sudo chown -R {username}: $HOME/.themes.

    2.2. Now, lets verify the permissions. From the same output we checked before, the first column indicates permissions, this one may be a bit tricky to understand. I'll break it down for you:

    In my example, ls gave us drwxrwxr-x, we don't really care about the first letter d, it just indicates that we are dealing with a directory. Now, the next letters (r, w, x) we do care about, lets split them into sets of three or less, starting from the left. If you get other letters, like s or t, ignore them. If you have less than 3 letters, but they would repeat if put together, then they belong to a different set. Here's how the sets would look like:

    rwx               indicates file owner permissions
       rwx            indicates group permissions
          r-x         indicates anyone else's (other) permissions

    The w indicates Write permission, you should see it in the first set (file owner). If you don't, give yourself that permission issuing the following command: chmod ug+w $HOME/.themes.

Now you should be able to follow the first part of the instructions or use lxappearance to install other valid themes.

If you launch lxappearance as a normal user it will install themes locally. To install themes globally (for all users), launch lxappearance as root.
