Cannot update Home Assistant 0.45.1

Hello, I have been trying to update Home Assistant for a while now and the update fails every time. The working home assistant installation is running on a raspberry pi 3 (raspbian jesse )and i have tried to update is using

$ pip3 install --upgrade homeassistant

I always get the error below:

Installing collected packages: chardet, requests, pytz, astral, voluptuous, async-timeout, multidict, yarl, aiohttp, typing, MarkupSafe, jinja2, pyyaml, homeassistant
Found existing installation: chardet 2.3.0
Uninstalling chardet-2.3.0:
Exception:

PermissionError: [Errno 13] Permission denied: ‘/usr/bin/chardetect’ -> ‘/tmp/pip-j88l_lmk-uninstall/usr/bin/chardetect’

During handling of the above exception, another exception occurred:

What i have tried:
sudo su -s /bin/bash homeassistant
source /srv/homeassistant/bin/activate

(get an error here, gile not found)
pip3 install --upgrade homeassistant
exit

It depends how you installed HA in the first place as to how you upgrade it…

If AIO see here …

If not using a virtual env then you may need sudo pip3 install --upgrade homeassistant as it looks like you are having permission errors.

Thanks, i got it
