/etc/default/im-config leaves temporary variables fixed in environment

[David Cimadevilla]

Ubuntu 18.04
im-config 0.34-1ubuntu1.3

You can reproduce the issue following these steps:

- Open a X terminal
- echo $d
- Returns "GNOME"

The source is this line in /etc/default/im-config:

for d in 'Unity' 'MATE' 'GNOME'; do

the temporary variable d gets fixed in the environment variables.

Thanks for your report, but I can't reproduce it.

Can you please run:

apport-collect 1877627

[David Cimadevilla (davidcim)]

You are right. I've found that the issue happens also because I export $d in ~/.profile .

The updated list of steps to reproduce the issue:

- echo 'export d=my-env-var-data' >> ~/.profile
- Restart X session
- Open a X terminal
- echo $d
- Returns "GNOME"

Note: The installed display manager is sddm.

Exporting 'd' seems like a weird thing to do? In any case im-config could probably use a more specific variable name to avoid conflicts...

[Gunnar Hjalmarsson (gunnarhj)]

I made 'd' (and a couple of other temporary variables) local to avoid this issue. Uploaded to groovy.

This bug was fixed in the package im-config - 0.44-1ubuntu2

---------------
im-config (0.44-1ubuntu2) groovy; urgency=medium

  * debian/patches/01-ubuntu-default-mode.patch:
    - Declare temporary variables as local to avoid the risk that they
      alter environment variables (LP: #1877627).
