Uninstalled QGIS and now cannot reinstall it : qgis-plugin-grass

Seems to be the same to :

Uninstalled QGIS and now cannot reinstall it ("E: Unable to correct problems, you have held broken packages.")

But i didn't succeed with explanations.

I am using Ubuntu 20.04.3 LTS. I was using QGis version 3.16 on a computer and have a SRC problem. This problem wasn't encountered on other computer with same ubuntu but QGis 3.22. So I want to install Qgis 3.22. I've installed 3.22 whitout uninstalling 3.16 but some installation problems appears. So I've uninstall 3.16 and try installing 3.22 but have some issues i'm know not able to solve after some researches.

I have followed this tutoriel to instal QGis : https://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu

So after this command line :

sudo apt install qgis qgis-plugin-grass

I get this error:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies.
 qgis-plugin-grass : Depends: grass782
E: Unable to correct problems, you have held broken packages.

I have tried to install grass782 manually :

sudo apt install grass782

Returns :

Reading state information... Done
Package grass782 is a virtual package provided by:
  grass-core 7.8.2-1build3 [Not candidate version]
E: Package 'grass782' has no installation candidate

I have tried to install grass-core manually :

sudo apt install grass-core

Returns :

Reading state information... Done
grass-core is already the newest version (7.8.6-1~focal2).
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.

When I do :

grep -v "^#" -r /etc/apt/sources.list /etc/apt/sources.list.d/*.list | sort | uniq    /etc/apt/sources.list

I get :

Looking for held packages with the command dpkg --get-selections | grep hold, it doesn't return anything.

Curiously `sudo apt update` returns `All packages are up-to-date.` And when I do `sudo apt-get --only-upgrade install grass-core` it returns `grass-core is already the newest version (7.8.6-1~focal2).`

`sudo apt -s install --reinstall grass-core=7.8.2-1build3`this is only a simulation. If no error `sudo apt install --reinstall grass-core=7.8.2-1build3`

yes, `sudo dpkg --dry-run -P $(dpkg -l | grep qgis | awk '{print $2}')` this is also a simulation I'm concernd of this part `Aborted (core dumped)` Please add also `dpkg -l| egrep -v '^ii|rc'`

I have had the same error as you.

qgis-plugin-grass : Depends: grass782 E: Unable to correct problems, you have held broken packages.

I have uninstalled qgis and grass and removed broken packages. I have then reinstalled qgis according to the steps on their website. BUT I have used a different repository with help from this comment , namely:

deb [ arch=amd64 ] https://qgis.org/ubuntugis-ltr focal main

Note, that this is for the LTR version (3.16.xx). In your case, you want:

deb [ arch=amd64 ] https://qgis.org/ubuntugis focal main

As we had the same error, and this seemed to fix my problem, I hope it will also fix yours!

Note: During the steps on their website I came to the error of not being able to add a key. I don't know if this is related to our issue, but I will mention it just to be sure. This answer here helped me.

For me this command did the trick: sudo add-apt-repository "deb https://qgis.org/ubuntugis $(lsb_release -c -s) main" as is comented here https://github.com/qgis/QGIS/issues/38329#issuecomment-862453938

thanks. I've try the same. Uninstall grass `sudo dpkg -P grass grass-core grass-doc grass-gui` and reinstall QGis but same error `The following packages have unmet dependencies. qgis-plugin-grass : Depends: grass786 but it is not installable`. Not really the same it was grass782 before

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
