Seems I wrecked dpkg

For some reason I deleted the file: sudo rm /var/cache/debconf/config.dat

And then dpkg started complaining:

Firefox became very slow and strangely waits for 192.168.101.1:8888

10

Firefox started loading urls with a huge delay despite having a fast plan (70 MBit download)

Also in status line at the window bottom it sometimes prints waiting for 192.168.101.1:8888

My laptop is connected via WiFi with no dns-nameservers configured in /etc/network/interfaces and my router has wired connection to the ISP.

Who does that IP address belong to? Why does my browser wait for that strange address?

I removed many of linux-images of 3.13.0-x versions, I left few versions installed.

As you can see there are only 3.13.0-x versions.

But also I have a lot of linux-headers for 3.16.0-x and 3.19.0-x versions.

Why?

As I don't have 3.16 and 3.19 kernels, why does my system downloads and installs all these 3.16 and 3.19 headers?

How to get the list of installed packages without dependencies?

11

Software Center somehow shows quite short list of installed packages. How to get it in text file?

I tried:

> dpkg --get-selections|wc -l
3265

> aptitude search '~i!~M'|wc -l
1181

> dpkg -l | grep ^ii | sed 's_  _\t_g' | cut -f 2|wc -l
3076

> dpkg --get-selections | grep -v deinstall|wc -l
3076

> apt-mark showmanual|wc -l
1181

I know that I've installed few dozens packages, not thousands. I need in the list exactly packages I'd choosen without dependencies to review it.

UPDATE

Many thanks to @kos, I got finally the list with that command:

> zcat /var/log/apt/history.log.*.gz | cat - /var/log/apt/history.log | grep -Po '^Commandline: apt-get install \K.*' | tr ' ' '\n' | grep -v '\-\-reinstall'|grep -v '\-\-force-yes'|grep -v '\-y'|grep -v '\-f'|sort|uniq wc -l

How to check if ureadahead functioning

I got spinning 5400 rpm 1Gb drive.

Booting takes 69 seconds (is it slow?) and /var/lib/ureadahead contains empty directory debugfs. That is why I wonder if ureadahead does its job.

/var directory is on root partition

Can't get rid of Gnome SSH Agent

When I type in a terminal git -T [email protected] the dialog with the title "Unlock private key" appears with password entry field.

I guess it is Gnome Keyring SSH Agent, and I would like not to use it but to use instead ssh-add command to add keys.

I edited /etc/xdg/autostart/gnome-keyring-ssh.desktop but that didn't help. In "Startup Applications" settings it looks as disabled.

I googled some and checked out two first links it found:

They don't mention what shall I do in case of such warnings:

Warning: The command '/bin/which' has been replaced by a script: /bin/which: POSIX shell script text executable
Warning: The command '/usr/sbin/adduser' has been replaced by a script: /usr/sbin/adduser: a /usr/bin/perl script text executable

Q1: Is there more extended HowTos which explain how to deal with different kind warnings?

And the second question. Were my actions sufficient to resolve these warnings?

a) To find the package which contains the suspicious file, e.g. it is debianutils for the file /bin/which

~ > dpkg -S /bin/which
debianutils: /bin/which

b) To check the debianutils package checksums:

~ > debsums debianutils

How to clear a Firefox address bar without selecting its content?

6

Sometimes I need to move an url from an app to a browser. I select the url, say in gvim, and make Firefox window active. Then I see that I should clear address bar before pasting the new url, which requires selecting existing url, which wipes the new url from PRIMARY clipboard out.

What is the best way to put the new url from PRIMARY clipboard to address bar? Is there a shortcut to clear address bar and then to move focus there?

ps I know I can use Ctrl-C to put the new url to CLIPBOARD clipboard, but I prefer to use PRIMARY clipboard.

Each time I've been looking for "something I don't know exactly what" in big text file, e.g. log-file, huge shell script, I wish to hide all the lines of certain types.

I wish to select certain lines with a set of regexps and either hide them or highlight.

It would be nice if I could select line blocks e.g. those lines between "function ...() {" and corresponding "}"

can you suggest me such a viewer?
