-Qi and -Qs find uninstalled packages when they weren't purged

[schra]

For example, I deinstalled the following package:

$ pacman -R unattended-upgrades
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages were automatically installed and are no longer required:
  daemon libjs-angularjs libjs-d3 libjs-moment
Use 'sudo apt autoremove' to remove them.
The following packages will be REMOVED:
  unattended-upgrades
0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.
After this operation, 418 kB disk space will be freed.

Altough I deinstalled the package, I can still find with via -Q:

$ pacman -Qs unattended-upgrades

Description: automatic installation of security upgrades
 This package can download and install security upgrades automatically
 and unattended, taking care to only install packages from the
 configured APT source, and checking for dpkg prompts about
 configuration file changes.
 .
 This script is the backend for the APT::Periodic::Unattended-Upgrade
 option.

Purging the package fixes the problem:

$ sudo apt-get --purge remove unattended-upgrades

$ pacman -Qi unattended-upgrades
dpkg-query: package 'unattended-upgrades' is not installed and no information is available
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.

My expectation is that removed but un-purged packages are not found via -Qs and -Qi.

Hi @schra ,

Sorry for my belated response. I didn't configure my notification system correctly and I lost all Github information.

Can you please try pacman -Rn (

pacapt/lib/dpkg.sh

Line 90 in 735b2ea

dpkg_Rn() {

)

Thanks

@schra Recently I have had chance to use the purge option. This is what I did on some ubuntu systems:

$ pacapt -R --purge filebeat fail2ban

and that did actually purge all configuration files within the packages. Hope this helps.

My expectation is that removed but un-purged packages are not found via -Qs and -Qi.

I think the behavior is actually how apt-based system is working, and I don't think it's a good idea to fix their behavior from our tool. cc @cuonglm fyi
