Unmet dependencies python3.9

apt package-management python dpkg

13,753

Solution 1

This worked for me. I found the packages that errored out and installed them using dpkg:

sudo dpkg -i --force-all /var/cache/apt/archives/libpython3.9-stdlib_3.9.12-1+bionic2_amd64.deb
sudo dpkg -i --force-all /var/cache/apt/archives/libpython3.9-minimal_3.9.12-1+bionic2_amd64.deb

Note: You may have a different version of these packages which can be found using ls /var/cache/apt/archives/ | grep libpython3.9-

Then I could update:

sudo apt-get update -y && sudo apt-get install --fix-broken

Solution 2

You have unnecessary PPA repository added. To remove it use commands below:

# sudo apt-get install ppa-purge
cd ~/Downloads
apt-get download ppa-purge
dpkg -x ppa-purge_0.2.8+bzr63_all.deb ppap
sudo cp ppap/usr/sbin/ppa-purge /usr/local/bin/

sudo ppa-purge ppa:deadsnakes/ppa # first for bionic
sudo ppa-purge ppa:deadsnakes/ppa # second for focal

and then reinstall normal python versions from official 20.04 LTS repositories:

sudo apt-get install python3.9=3.9.5-3~20.04.1 libpython3.9-stdlib=3.9.5-3~20.04.1 \
libpython3.9-minimal=3.9.5-3~20.04.1 python3.9-minimal=3.9.5-3~20.04.1 --reinstall

Then install Aptitude with

sudo apt-get install aptitude

and resume package installation by

sudo add-apt-repository main
sudo add-apt-repository universe
sudo add-apt-repository multiverse
sudo add-apt-repository restricted

sudo apt-get update
sudo apt-get install -f
sudo dpkg -i --force-all /var/cache/apt/archives/libpython3.9-stdlib_3.9.5-3~20.04.1_amd64.deb /var/cache/apt/archives/libpython3.9-minimal_3.9.5-3~20.04.1_amd64.deb

sudo dpkg --configure -a
sudo aptitude install python3.9=3.9.5-3~20.04.1 libpython3.9-stdlib=3.9.5-3~20.04.1 \
libpython3.9-minimal=3.9.5-3~20.04.1 python3.9-minimal=3.9.5-3~20.04.1
sudo aptitude dist-upgrade

Solution 3

This article helped me dpkg error code 1

sudo dpkg --configure -a
sudo apt remove --purge python3.9-minimal python3.9
sudo apt autoremove
sudo apt upgrade

I am trying to update Ubuntu and correct some system settings, however I am facing an issue I have been stuck on for over a week now.

When I type sudo apt-get install, I get:

The following packages have unmet dependencies.
 python3.9 : Depends: libpython3.9-stdlib (= 3.9.5-3~20.04.1) but 3.9.5-1+bionic1 is installed
 python3.9-minimal : Depends: libpython3.9-minimal (= 3.9.5-3~20.04.1) but 3.9.5-1+bionic1 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

So I run sudo apt --fix-broken install and get:

The following additional packages will be installed:

E: Sub-process /usr/bin/dpkg returned an error code (1)

I have tried a few things and searched for the errors in a few forums and I cant find a solution. It's really puzzling me.

I have even tried removing:

$ sudo apt remove libpython3.9-minimal/bionic libpython3.9-stdlib/bionic python3.9-minimal/focal-updates

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies.

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Any help would be great!

What is your Ubuntu version? Why do you mix 18.04 (bionic) with 20.04 (focal) repos? Please also add output of apt-cache policy python3.9 libpython3.9-stdlib libpython3.9-minimal python3.9-minimal to the question.

Why do you mix 18.04 (bionic) with 20.04 (focal) repos? - I am not sure why this has happened

Please show your current list of the repositories - execute grep "^deb\ " -r /etc/apt/ --include=*.list and python sources apt-cache policy python3.9 libpython3.9-stdlib libpython3.9-minimal python3.9-minimal - add output to the question. If long - use pastebin.

Isn't faster to just sudo apt autoremove --purge python3.9-minimal python3.9 ?

In my case it says minimal is dependency of stdlib so I had to install minimal first. But those are the files. Thx.
