I have got this error from launchpad:

cp __targets_dynlib/anonpy.so /usr/lib/python3/dist-packages/
cp: cannot create regular file '/usr/lib/python3/dist-packages/anonpy.so': Permission denied

How do I fix that?

I need to have use DESTDIR and PREFIX on that line also

cp __targets_dynlib/anonpy.so $(DESTDIR)$(PREFIX)/lib/python3/dist-packages/

To get an update lens db, I need a newer version of libexiv2 than is currently in the repo. Specifically I need version 0.27 or later. I tried to build it from source, and installed it in /usr/local. Now I want Darktable to find the new version. Tried

sudo ldconfig

And modifying LD_LIBRARY_PATH, but it still loads the old version. Should I download a new Darktable too, and compile that against the new version or would replacing the symlink be sufficient.

It appears that the font preview tool gnome-specimen has been removed from 18.04. A quick search makes it look like it is outdated. Are there an replacement packages that I can use instead? Kfontview is present, but that would require me to pull the entire plasma desktop:

Command kfontview not found, but can be installed with:

sudo apt install plasma-desktop

I am not happy to do install another DE (currently using Xfce). I have disk space, but I want to save time when upgradeing packages 2 DEs => more upgrades to install.

An Ubuntu installation may vary hugely in size, depending on the installed packages. Is there any quick way to check how mutch disk the current installation uses.

I want to know, because I plan to build a new PC, with a smaller and fast SSD for / and a large mechanical drive for /home (I have need for a large home directory), to decresase boot time. To solve this problem I would like to know the size of my current installation, so I know how large the system file system needs to be for my use.

What is the time limit when building source packages at launchpad servers? That is, what is the time limit before the server will abort the building process.

I have a package named maike_0.16.1-1milasudril1.deb compiled for Zesty. I have uploaded a newer version for Xenial, with name maike_0.17.0-1milasudril1.deb, and want to push one for Zesty as well. I thought launchpad could be smart enough to put these packages in different categories based on the release tag, but it does not use that information. Instead the package name has to be different, so I tried to put Zesty in different places, but it does not take it. Is this because it assumes

`0.16.1-few extra letters` > `0.17.0-other extra letters`

or what is going on. Can I fix the issue without bumping upstream version number?

Firefox bug #1345661 was closed with "WONTFIX", which certainly will break my current setup in the near future (I play firefox sound through alsa_in:loopback->JACK). I have read that Firefox has JACK support now, though it is not yet stable. Questions:

1. Will JACK support in Firefox be officially supported?
2. Will Ubuntu enable JACK support in Firefox before raw ALSA support ends?

I the answer is No No, how can I reliable restore functionality without breaking JACK? It is possible to run PA through alsa_in, but I guess that would introduce some extra latency, break AV sync, or introduce signal distortion due to multiple resamplers.

My laptop (Asus e402s) have the following built in devices:

card 0: PCH [HDA Intel PCH], device 0: ALC256 Analog [ALC256 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

There is one (this is stupid, since anyone knows that thou shalt never connect two output ports, and if the software dictates what it is, you may blow your components...) analog port which is either microphone or headphone. I want to use the jack as an analog output for headphones. How can I fix that? Currently, I have no sound in the headphones, but the speakers work.

The file system scan stops for a while at 95 %, but running fsck from emergency prompt works.

After removing KDE and switching to xfce, I discovered that Kate has lost all button icons, while Kile has not. I guess some configuration file refers to missing files, but what file is it. I tried to create a new, clean, user account, but the problem remains. In particular the search buttons has disappeared, since they have no text on them.

Update

A fresh install of Xubuntu on a second drive gives the same error:

It is the same machine, booted from an external USB hard drive

The "Open" dialog box is not affected. Only toolbars and the "Save as" dialog are broken. I suspect a packaging bug.

This question may belong to Unix/Linux in general, but I guess the answer is dependent on distro or desktop environment [I use KDE and Xfce so I would like an answer that is applicable on booth].

Consider this simple GTK app:

#include <gtk/gtk.h>

static void print_hello(GtkWidget *widget, gpointer data)
    {
    g_print ("Hello World\n");

//  Intentional crash
    int* badfood=NULL;
    *badfood=1;
    }

int main(int argc,char *argv[])
    {
    GtkWidget *window;

    gtk_init (&argc, &argv);

    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
    g_signal_connect (window, "destroy", G_CALLBACK (gtk_main_quit), NULL);
    gtk_widget_show  (window);

    GtkWidget* button = gtk_button_new_with_label ("Crash this app");
    g_signal_connect (button, "clicked", G_CALLBACK (print_hello), NULL);
    gtk_container_add (GTK_CONTAINER (window), button);
    gtk_widget_show (button);

    gtk_main ();
    return 0;
    }

The program will crash with SIGSEGV when the user clicks "Crash this app". If run from the terminal, I get a notice:

$ ~/Skrivbord/gtktest/test 
Hello World
Segmenteringsfel (minnesutskrift skapad)

And I am happy, but starting it through the launch box...

The window only disappears without any visible notice about a program crash. In the latter case, I want a message appear telling me something like

~/Skrivbord/gtktest/test has caused a segmentation fault

much like I get in Windows.

When I logout from KDE and log in on tty1, I see the message "Jack is already running". When listing processes, I see that I have started it, so I conclude that jack never stopped. How could that be?

Here is what I see from ps -u when logging in from tty1:

  PID TTY          TIME CMD
 2053 ?        00:32:39 jackd
 2079 ?        00:00:00 alsaj
 2082 ?        00:11:00 alsa_in
10265 tty1     00:00:00 bash
10295 tty1     00:00:00 ps

Why do I still see jackd and alsa_in among running processes?

Follow-up:

Since the processes does not die when logging out, there has to be a corresponding log-out script that does not run as root. Is there a way of cleaning up any side-effects caused by .profile?

Is it possible to test which menu item was used to start the system. If the choice of kernel was different i can for example do this in my login script

if uname -r | grep -q lowlatency; then
    jack-start
fi

But relying on kernel release seams ugly. I like to use the boot menu for such things is that I use the boot menu for choosing kernel/operating system anyway so doing more after startup takes more time.

Possible solutions i thought of other than using uname are

• Set an environment variable when invoking the boot-menu entry. If this is possible is quite nice

• I have configured grub to remember last used entry. Can I get what entry it was from somewhere? Yes, I found the file /boot/grub/grubenv

Is there a replacement package for the deleted KGraphViewer?

The qt dev pacakage is installed. Compilation of the latest Umbrello works.

Also I tried to compile it from the git remake -DCMAKE_INSTALL_PREFIX=/usr/local ..

Did the kernel size increased much between 3.13.0-24 and 3.13.0-27. I got trouble when trying to install the automatic upgrade. I have two kernels installed:

• linux-image-3.13.0.24-generic
• linux-image-3.13-0-24-lowlatency

This question is a follow-up from https://unix.stackexchange.com/questions/126955/percent-in-path-environment-variable. I post it here, since it is more distro-specific.

The shell used by default for sh namely dash, is not compatible with execvp because it fiddles with the $PATH variable. A standardized way of dealing with strange filenames is to use URL encoding scheme. Now I cannot use that standard because dash reserves %. To solve this I problem I have the following options

1. Recommend my users on Ubuntu to change the symbolic link /bin/sh to something else like bash. It is necessary to do it globally since popen(3) relies on /bin/sh.

2. Diverge from traditional URL encoding by using something other than %

3. Throw an error whenever any of the Forbidden characters (yes, Windows but these restriction is sane in a dual-boot configuration) appears.

Ideally I prefer option (1) seems the best way to go. It makes it possible to use a standardized escape scheme in filenames. However, since dash clearly behaves differently than some other shells, it will break the system if any of the system scripts rely on functionality unique to dash. Also it requires that the user has root privileges.

Option (2) implies that I have to find another symbol that does not collide anywhere. Certainly, some shell may screw up any symbol that is not a letter.

Option (3) implies too large reduction in functionality

I am on Ubuntu 14.04 (i686).

I read that there is one or more reported bugs related to this issue. I do not know if they are fixed as they appear to be in 11.10.

Here is HW info and what I have tried:

• The computer is Dell Latitude d510

• NIC is reported as a DWA-140 Ralink RT5372

• My desktop environment is XFCE

• The password is correct

• I tried available for all users

• I have wpasupplicant

• The connection works in Windows XP on the same machine

• Connecting to another wi-fi using WPA2/Enterprise seems to work

It worked but I needed a re-install. I have some succeeded connecting manually:

wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf -Dwext && dhclient wlan0

This locates the problem to NetworkManager

I have a dell latitude d510 currently running xubuntu 13.04 and linux 3.8. I want this machine to host JACK processes together with EDIROL UA-25 during a live session and therefore, it needs an RT kernel. Since this is a laptop, I do like to have no RT kernel installed also saving power. How can I configure this?

This question is somewhat similar to How to use Windows Share has home directory, but in this case Windows is not running.

I have installed a dual-boot configuration with Ubuntu 12.04 and Windows. My Windows partition is mounted on /C. Now I want either Ubuntu to locate home directories in

/C/Users

Which is the location of windows accounts

or I want Windows to use

D:\home

for home directories. (D is the name of the Ubuntu root directory).

For the first approach, I have managed to create a test user account

test-user:x:1004:1001:Test:/C/Users/test-user:/bin/bash

The account works but test-user cannot run any X session. From .xsession-errors

chmod: Changing rights on ”/C/Users/test-user/.xsession-errors”: Operation not permitted

Would it help get rid of that chmod, which has no effect? How do I?

If I use the second approach, I need the Ext2fsd driver, which seems to work, but I am not sure if Windows maps the Ext2 system that early.

Here is my fstab

proc            /proc           proc    nodev,noexec,nosuid 0       0
UUID=e7cef061-ed8d-4a82-b708-0c8f4c6f297f /               ext3    errors=remount-ro 0       1
UUID=2CDCEB43DCEB0644 /C              ntfs    defaults,umask=007,gid=46 0       0
UUID=b087b5c0-b4bd-47e7-8d34-48ad9b192328 none            swap    sw              0       0

Update: I found something here: http://www.tuxera.com/community/ntfs-3g-advanced/ Will work if i do a correct mapping between NT users and Linux users.

After upgrading to 12.04, my Logitech M515 does not work here is some output from the terminal:
