Guake is not setting/exporting the TERM variable properly

[behrangsa]

I am not behind my Linux machine so I might miss some of the details now, but in short some programs depend on the TERM variable to be exported and have a reasonable/meaningful value, but under Guake they complain that TERM is not set.

I think the issue is similar to this Launchpad bug

guake is exporting $TERM in my environment:

$ echo $TERM                                                                                                                                                                         
xterm-256color

It looks like this fix does not work properly, in my guake:

$ echo $TERM                                          
xterm
$ grep xterm /usr/lib64/python2.7/site-packages/guake/main.py
    # Force to xterm-256 colors for compatibility with some old command line programs
    os.environ["TERM"] = "xterm-256color"

Could it be setting the environment variable for within the program but not in the terms emulated?

Are you sure you don't have something in your .bashrc or .profile?

[dayer3]

I've the same problem.

My .bashrc:

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
    . /etc/bashrc
fi

# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=

# User specific aliases and functions

My .bash_profile:

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH

if [ -z "$SSH_AUTH_SOCK" ] ; then
  eval `ssh-agent -s`
  ssh-add
fi

My /etc/bashrc:

# /etc/bashrc

# System wide functions and aliases
# Environment stuff goes in /etc/profile

# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.

# are we an interactive shell?

I see something of TERM in /etc/bashrc but I don't know if it has influence.

[gsemet]

Ok, reproduced by using /bin/sh shell. I'll check this asap. Also found an issue when changing shell...

[thardev]

Hi all! 😃
After some research I found that this is an obsolete dependency issue. In this case VTE library again 😢.
Like you can see in this bug report is similiar and is up-to-date, so they reference this bug report, that one is older and it affects to gnome-terminal, but it's fixed. There's a discussion too in this post and they say that maybe is not the best idea to mess with TERM env.

[ghost]

As I understand those bugreports, the a libvte-2.91 package (vte 0.38+) would fix this. Does any Ubuntu PPA exist, which ships Guake compiled against that version?

[Davidy22]

Closing as this has been fixed upstream for a few years now and can no longer replicate with /bin/sh

[tp1050]

I am having this issue myself, none of the Environmental variables I set in /etc/profile.d/
