Setting up update-notifier-common (3.192.1.15) ...
Traceback (most recent call last):
File "/usr/lib/update-notifier/package-data-downloader", line 24, in <module>
import debian.deb822
File "/usr/lib/python3/dist-packages/Debian/deb822.py", line 78, in <module>
class TagSectionWrapper(collections.Mapping):
AttributeError: module 'collections' has no attribute 'Mapping'
dpkg: error processing package update-notifier-common (--configure):
installed update-notifier-common package post-installation script subprocess returned error exit status 1
Errors were encountered while processing:
update-notifier-common
E: Sub-process /usr/bin/dpkg returned an error code (1)
Looking online it looks like that the issue is caused by a missing collections.Mapping attribute in the debian.deb822 module. To resolve the issue I should:
- List item
Remove the package update-notifier-common
sudo dpkg --remove --force-remove-reinstreq update-notifier-common
- Update apt, and reinstall
update-notifier-common
sudo apt-get install update-notifier-common
The problem is that I can't pass the 1st step because I got this error message:
sudo dpkg --remove --force-remove-reinstreq update-notifier-common
dpkg: dependency problems prevent removal of update-notifier-common:
ubuntu-server depends on update-notifier-common.
dpkg: error processing package update-notifier-common (--remove):
dependency problems - not removing
Errors were encountered while processing:
update-notifier-common
I checked update-notifier-common dependencies and it doesn't look good:
$ apt-cache rdepends update-notifier-common
update-notifier-common
Reverse Depends:
update-notifier
flashplugin-installer
ubuntu-server
debconf
ttf-mscorefonts-installer
apt-config-auto-update
reboot-notifier
apt-config-auto-update
update-notifier
debconf
ubuntu-server
byobu
How can I safely remove update-notifier-common without messing up the whole OS?
