What's wrong with apport and

dpkg: error while cleaning up:

and

subprocess installed post-installation script returned error exit status 127

l tried :

sudo dpkg --purge --force-all apport

then l got :

dpkg: warning: overriding problem because --force enabled:

Errors were encountered while processing:
 apport

after that :

I checked and can confirm that both /var/lib/dpkg/info/apport.postinst and /var/lib/dpkg/info/apport.prerm exist on the system.

all the following commands didn't work for me :

sudo apt-get install apport --reinstall
sudo dpkg --purge --force-all apport
sudo apt-get clean 
sudo apt purge apport
sudo apt install apport
sudo apt -f install
udo dpkg -i --force-overwrite apport
dpkg -i --force-overwrite /var/cache/apt/archives/apport_2.20.1-0ubuntu2.6_all.deb
sudo apt-get -o Dpkg::Options::="--force-overwrite" install apport-dev

edit1 l tried also

sudo dpkg -r man-db but l get stuck here :

    dpkg: error processing package man-db (--remove):
     dependency problems - not removing
    Errors were encountered while processing:
 man-db

then the folwing can't be run

sudo dpkg -r apport 
sudo apt-get upgrade
sudo apt-get install -f

Solution

i had the same error, so I'm fixed it using this

sudo dpkg --purge path/package.deb
sudo apt-get -f install
sudo apt-get update && sudo apt-get upgrade
