Software Manager doesn't Open

[MaCK0y]

Hi,

First Post. Not a linux guru. I have had this problem for more than a year but I rarely install software and when I needed I used apt so I didn't bother to solve it but now I think certain updates related to this issue are breaking things.

I searched about this issue including this forum but nothing helped. Basically when I try to open Software Manager or Software Sources, they don't open. If I try to run mintinstall/mintsources from terminal I get the following:

I searched this line

Code: Select all

async = reply_handler and error_handler

and one of the suggestions was to rename async for eg to async_ for every entry in that file. But nothing changed I think this has something to do with python3 and aptdaemon and the versions that I have installed and the version of Mint I am running. In fact I am afraid of trying to update anything related to python and aptdaemon because everything got messed up including apt got broken and couldn't install/upgrade packages with it anymore. Or maybe it happened because I tried removing and reinstalling python. Can't remember. Timeshift saved the day.

Thanks for the help!

Try

Code: Select all

 sudo apt update; sudo apt install mintinstall 

[mikeflan]

sudo mintinstall

Please do as deepakdeshp recommends. Then don't use sudo to run mintinstall. Just type:

Code: Select all

mintinstall

When I type sudo mintinstall I get:

Code: Select all

sudo mintinstall
[sudo] password for mike:     
The software manager should not be run as root. Please run it in user mode.

[MaCK0y]

I already tried uninstalling and reinstalling mintinstall. I don't think it's mintinstall or mintupdate that is the problem but I think something to do with python3 but have no idea how to fix it. Running mintinstall without sudo produces the same errors.

[deepakdeshp]

If you have uninstalled Python 3 you have to reinstall it.if that doesn't solve it, go back to TimeShift backup or Clonezilla backup by restoration, if you have the backups.

Also check your disk.https://help.ubuntu.com/community/Smartmontools Was there unplanned shutdown where some inodes were cleared by fsck ?

[mikeflan]

Try reinstalling Python3 first. Then if you are desperate try this.
Backup/var/lib/apt/lists/:

Code: Select all

sudo cp /var/lib/apt/lists/* somebackupdirectory

Remove all apt lists:

Code: Select all

sudo rm  -vf /var/lib/apt/lists/*

Code: Select all

apt-get update

Code: Select all

apt-get upgrade

Warning: This may be bad advice.

Phython3 is installed. I tried again to do those python and aptdaemon updates from the Update Manager and this is what I get.

This async = reply_handler and error_handler error is probably the key to solve this. The python updates get installed but not the aptdaemon. After the updates, I have broken dependencies

Code: Select all

sudo apt-get check

Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 aptdaemon : Depends: python3-aptdaemon (= 1.1.1+bzr982-0ubuntu19.3) but 1.1.1+bzr982-0ubuntu19.5 is installed
 python3-aptdaemon.gtk3widgets : Depends: python3-aptdaemon (= 1.1.1+bzr982-0ubuntu19.3) but 1.1.1+bzr982-0ubuntu19.5 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

The command apt --fix-broken install doesn't work or maybe I'm doing it wrong. Then I tried the following:

Code: Select all

Nevermind. Solved it. Thanks to https://linuxmint.com.ru/viewtopic.php?t=4617. Ran the follow command and fixed it. Probably missed a few when I tried to do it manually.

Code: Select all

sudo sed -i 's/async/async_/g' /usr/lib/python3/dist-packages/aptdaemon/client.py

The aptdaemon update still doesn't work and breaks software Center so it's going to the blacklist.

Edit: When I try to install something from Software Manager it complains about aptdaemon. I think I'm done with Software Manager.
