[solved] Uninstalling gnunet

[cefk]

Hi,

I was interested in gnunet and just installed it, blindly to try it out.

Installed via:
$ sudo apt-get install gnunet

Now I can't uninstall it.

After issuing:
$ sudo apt-get purge gnunet

it seemed to get uninstalled (and apt actually thinks that it's gone), but it is still there (files in /usr/bin/gnunet* and god knows, what else .. and where).
So is the virbr0-interface and a dnsmasq-process .. that caught my eye, first. :\

$ ps aux | grep dnsmasq
dnsmasq --strict-order --bind-interfaces --pid-file=/var/run/libvirt/network/default.pid --conf-file= --except-interface lo --listen-address 192.168.122.1 --dhcp-range 192.168.122.2,192.168.122.254 --dhcp-leasefile=/var/lib/libvirt/dnsmasq/default.leases --dhcp-lease-max=253 --dhcp-no-override

I'm not a newb, but I've never touched dnsmasq or configured network bridges, yet.

Since this is really annoying:
Can anyone please help and tell me, what I need to do in order to find everything that has been changed by installing gnunet and to undo these changes?
Or will I have to learn not to just install packages - trusting, that I will be able to completely uninstall them - the hard way and wipe/reinstall my whole system?

Thanks in advance

Gnunet

:~$ apt-cache show gnunet

Depends: gnunet-client, gnunet-server, gnunet-tools

Description: secure, trust-based peer-to-peer framework (meta)
 GNUnet is a peer-to-peer framework which focuses on providing security. All
 link-to-link messages in the network are confidential and authenticated. The
 framework provides a transport abstraction layer and can currently encapsulate
 the peer-to-peer traffic in UDP, TCP, or SMTP messages.
 .
 This package is a metapackage depending on gnunet-client, gnunet-server and
 gnunet-tools.

MetaPackages

https://help.ubuntu.com/community/MetaPackages:

...These packages do not contain actual software, they simply depend on other packages to be installed...

Try to remove the gnunet-client, gnunet-server, gnunet-tools.

Re: Uninstalling gnunet

Thank you very much for saving my day

Everything I've mentioned before is gone, but one: The virbr0 interface ..

I'll try if a reboot does the trick and then post, if it helped.

EDIT: The reboot didn't help. virbr0 is still there.

Re: Uninstalling gnunet

You probably already done it but maybe,

sudo apt-get autoremove

Re: Uninstalling gnunet

Yes, I've tried it, but the virbr0-interface is still there.

But thanks anyway.

Simulation

Dependencies: gnunet -> gnunet-client, gnunet-server, gnunet-tools -> More packages

At here:

:~$ apt-get install -s gnunet
NOTE: This is only a simulation!
   apt-get needs root privileges for real execution.
   Keep also in mind that locking is deactivated,
   so don't depend on the relevance to the real current situation!
Reading package lists... Done
...
The following extra packages will be installed:
 gnunet-client gnunet-common gnunet-server gnunet-tools guile-1.8-libs libadns1 libesmtp6 libextractor-plugins
 libextractor1c2a libglade2-0 libmicrohttpd5
Suggested packages:
 adns-tools libextractor-java python-extractor
The following NEW packages will be installed:
 gnunet gnunet-client gnunet-common gnunet-server gnunet-tools guile-1.8-libs libadns1 libesmtp6
 libextractor-plugins libextractor1c2a libglade2-0 libmicrohttpd5

Logs/Package managers

The Synaptic and the Muon package managers are keeping history logs or parsing the apt/dpkg log.

With the Debian based the installed/updated/removed packages are ending to the the dpkg log.

Checking installed/updated/removed packages from the dpkg log (command line):

Recent status log:

grep "status installed" /var/log/dpkg.log

grep upgrade /var/log/dpkg.log

grep remove /var/log/dpkg.log

A bit older dpkg log:

grep "status installed" /var/log/dpkg.log.1

grep upgrade /var/log/dpkg.log.1

grep remove /var/log/dpkg.log.1

The oldest logs - rotated dpkg logs (packed): dpkg.log.2.gz, dpkg.log.3.gz...


Testing/experimenting

Keeping own logs. There is the logsave command:

:~$ man logsave

NAME
    logsave - save the output of a command in a logfile

SYNOPSIS
    logsave [ -asv ] logfile cmd_prog [ ... ]

DESCRIPTION
    The logsave program will execute cmd_prog with the specified argument(s), 
    and save a copy of its output to logfile.
    If the containing directory for logfile does not exist, logsave will 
    accumulate the output in memory until it can be
    written out. A copy of the output will also be written to standard output

logsave testing_something.log sudo apt-get install something

With the log file it is a bit easier to remove/purge the unwanted packages.

Re: Uninstalling gnunet

This does the trick:

$ sudo apt-get purge dnsmasq*

Re: Uninstalling gnunet

Thank you, OneLine!
I removed the packages your install-simulation showed, too.

I'll take your advice to heart for future installs (logging).

Thanks everybody!
