Hi<br>
<br>
I followed the instructions in <br>
<a href="https://medium.com/@moreless/install-python-3-6-on-ubuntu-16-04-28791d5c2167" rel="noreferrer noreferrer noreferrer" target="_blank">https://medium.com/@moreless/install-python-3-6-on-ubuntu-16-04-28791d5c2167</a><br>
and in fact installed python 3.8<br>
<br>
I cannot de install python 3.5 because a huge amount of package depend<br>
on python 3.5<br>
<br>
However when I follow the instruction <br>
<br>
hg clone <a href="https://kallithea-scm.org/repos/kallithea" rel="noreferrer noreferrer noreferrer" target="_blank">https://kallithea-scm.org/repos/kallithea</a> -u stable<br>
cd kallithea<br>
python3 -m venv ../kallithea-venv<br>
. ../kallithea-venv/bin/activate<br>
pip install --upgrade pip setuptools<br>
pip install --upgrade -e .<br>
python3 setup.py compile_catalog # for translation of the UI<br>

Well python3 was symbolically still linked to python3.5 <br>
<br>
So I changed that set the link from python 3.8 to python 3<br>
<br>
Did not work, <br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">In general you should avoid changing such links manually.
