How to install TortoiseHG with integration to Caja on Ubuntu MATE 20.04 LTS?

Question

On previous systems like Ubuntu 16.04 LTS and 18.04 LTS it was possible.

But 20.04 LTS do not have tortoisehg and tortoisehg-caja in the repositories.

What to do?

Answer 1

It is still possible, but by manual installation of packages.

One can use the method below based on obtaining packages from Ubuntu 20.10:

# 1. Get the newest Mercurial with Python 3 support
cd ~/Downloads
wget https://launchpad.net/ubuntu/+source/mercurial/5.5.1-1/+build/19906561/+files/mercurial-common_5.5.1-1_all.deb
wget https://launchpad.net/ubuntu/+source/mercurial/5.5.1-1/+build/19906561/+files/mercurial_5.5.1-1_amd64.deb
2. Install Mercurial packages
sudo apt-get install ./mercurial*.deb -y
3. Get dependencies for TortoiseHg
sudo apt install python3-all-dev python3-pyqt5 python3-pyqt5.qsci python3-iniparse -y
4. Get sources of TortoiseHg
hg clone https://foss.heptapod.net/mercurial/tortoisehg/thg
cd thg
hg checkout 5.5.1
5. Compile TortoiseHg using Python 3
sudo apt-get install python-is-python3
make local
sudo python3 setup.py install
6. Install TortoiseHg extension for Caja
mkdir -p ~/.local/share/caja-python/extensions
cp /usr/local/share/nautilus-python/extensions/nautilus-thg.py ~/.local/share/caja-python/extensions/caja-thg.py

and then restart Caja with caja -q && caja.

As the result one will get full functionality of Mercurial with TortoiseHG front-end in Caja:

• the same emblems

  

• and dropdown menus

Notes:

1. 20201019 - Ubuntu 20.10 repositories provide python3-based Mercurial packages.
2. Ubuntu 20.10 have needed packages, so we can replace step 1 by sudo apt-get install mercurial and then proceed with next steps. I have tested this method on Ubuntu MATE 20.10. It works well!

THANK YOU N0RBERT !!

One tweak to N0rbert's instructions: you may want to pull the "stable" branch of tortoise. As of today (6/2/2020) the "Shelf" feature is broken on main branch but is fixed in stable.

hg clone https://foss.heptapod.net/mercurial/tortoisehg/thg -r stable

(old: the command was: hg clone https://bitbucket.org/tortoisehg/thg/ -r stable but it looks like that is now gone.)

After you complete all of N0rbert's instrutions, if you'd like an easy way to launch Tortoise, create a .desktop file:

gedit ~/.local/share/applications/tortoisehg.desktop

And paste in these lines (replace "developer" with your username) :

[Desktop Entry]
Name=TortoiseHG
Exec=/home/developer/tortoisehg/thg
Comment=Launch TortoiseHG
Terminal=false
Type=Application
Icon=/home/developer/tortoisehg/icons/thg_logo.ico

Now you can click the start menu ("Show Applications"), search for Tortoise, right-click it and add to favorites.
