Debian 11: Unable to locate package glances

You are here because you cannot find glances via apt, right? I got into the same issue but differently. I removed glances because it was giving the following error:

glances AttributeError: 'ThreadScanner' object has no attribute 'isAlive'

. And when I attempted to reinstall it back, SURPRISE! Not available :D

E: Unable to locate package glances

I gave up and went pip way

1. install necessary apt packages:

apt install python3 python3-dev python3-jinja2 python3-psutil python3-setuptools hddtemp python3-pip lm-sensors

2. install glances via pip:

pip3 install glances

3. see the work output below why I had to do this:

ln -s /usr/local/bin/glances /usr/bin/glances

4. Enjoy glances! 5. If you want to update glances, must do it via pip now:

18:21:14 root@eeny:~# pip3 install --upgrade psutil glances
