I'm getting an ImportError when trying to use Nala after installation:

$ sudo nala update
Traceback (most recent call last):
  File "/usr/bin/nala", line 5, in <module>
    from nala.__main__ import main
  File "/usr/lib/python3/dist-packages/nala/__main__.py", line 30, in <module>
    import nala.fetch as _fetch  # pylint: disable=unused-import
  File "/usr/lib/python3/dist-packages/nala/fetch.py", line 37, in <module>
    import typer
  File "/usr/lib/python3/dist-packages/typer/__init__.py", line 12, in <module>
    from click.termui import get_terminal_size as get_terminal_size
ImportError: cannot import name 'get_terminal_size' from 'click.termui' (/usr/lib/python3/dist-packages/click/termui.py)

This is on a server installation that has been upgraded to 22.04 and not from a fresh install of 22.04. From a historical perspective, this server was initially built with 12.04 and has been upgraded several times to 22.04.

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 22.04.2 LTS
Release:        22.04
Codename:       jammy

Nala was installed as follows:

sudo apt install nala

As a test, I installed Nala on a fresh installation of Ubuntu 22.04 in a Virtual Box machine, and it works fine. So it looks like the problem is associated with this system being an upgrade to 22.04.

I also did the following:

wget https://gitlab.com/volian/volian-archive/uploads/b20bd8237a9b20f5a82f461ed0704ad4/volian-archive-keyring_0.1.0_all.deb\

sudo apt install ./volian-archive*.deb
sudo apt --purge autoremove nala
sudo apt install nala

  • And the following resulted in no output:

    $ sudo apt-mark showhold

I don't know how to resolve this. Does anyone have any suggestions?

I also have nala installed on Ubuntu 22.04, and it works fine. So I think you're right that something happened during the upgrade.

I would suggest you uninstall (and purge) your current version of nala, and reinstall the latest version.

Remove (Purge) Old Nala

Remove the current version and all related packages and files:

sudo apt autoremove --purge nala

Use with caution: Be very certain that this only removes packages related to nala.

Now you can install nala in 2 ways: From Ubuntu repo or from Volian repo.

Install Nala from Ubuntu repo
sudo apt update && sudo apt install nala

Nala version from this repo will be 0.11.1~bpo22.04.1.

Install Nala from Volian repo

First install the repo and key:

wget https://gitlab.com/volian/volian-archive/uploads/b20bd8237a9b20f5a82f461ed0704ad4/volian-archive-keyring_0.1.0_all.deb
wget https://gitlab.com/volian/volian-archive/uploads/d6b3a118de5384a0be2462905f7e4301/volian-archive-nala_0.1.0_all.deb
sudo apt install ./volian-archive*.deb

Then install nala from the Volian repo:

sudo apt update && sudo apt install nala

Nala version from this repo will be 0.12.3.

From the info provided, it seems the python3-typer module hasn't been upgraded. Do so manually by running:

sudo apt install python3-typer=0.7.0-1
