I'm setting up a new Kubuntu laptop.

problem 1:
When I run samba, I get:
   could not find the program 'gksu'
I googled and learned that gksu is depricated, but I haven't been able
to figure out how to run samba. Also:
sudo system-config-samba says there are MANY errors
in /etc/samba/smb.conf which is strange because I didn't edit the
existing file.

problem 2:
I usually mount a shared drive on my Raspberry Pi with the following
fstab entry: 
//pi/PI-PUBLIC /mnt/PI-PUBLIC cifs
user,credentials=/etc/samba/auth.pi.solomon 0 0

Since I don't have samba running, I did:
//pi/PI-PUBLIC /mnt/PI-PUBLIC cifs
username=solomon,password=abc,rw,user 0 0

When I look at files on the mounted drive, the owner and permissions are
wrong. 
For example a file that should be:
-rw-rw-r--   1 solomon solomon 34 Jul 11 09:55 tst.txt
looks like this:
-rwxr-xr-x   1 root root 34 Jul 11 09:55 tst.txt

An update to what I wrote:
In Dolphin I can do:
smb://solomon at pi and I see all the files with correct owners and
permissions.

So this works, but NOT if I just click on the device in the left panel
of Dolphin or if I access files from konsole.

Subject: kubuntu minimum install
Message-ID: <20180718080956.3d2c8bd6@shlomo1.solomon>

I did a minimum install. But I see some strange behaviour regarding
some packages. 
For example - I didn't install Kmail:
1 - As expected I don't see it in the Application Launcher. 
2 - sudo dpkg -l|grep kmail  shows that Kmail IS installed. 
3 - both Muon and Discover  report that Kmail IS installed
4 - I don't see the program in /usr/bin
5 - which kmail does not give any output

So what's going on here?

BTW - same behaviour for knotes, korganizer, kaddressbook, kdepim

OK - I found the debsums command and discovered about 150!!! broken
packages.   

I piped the results from debsums into apt-get install --reinstall and
fixed this.

Of course, now I'll have to manually un-install Kmail, Kaddressbook,
etc which I didn't want in the first place.

Can anyone suggest why there were so many broken packages?

Hi all,

A couple days ago I installed Void Linux on a Dell Inspiron 15-5570
laptop, using all EFI and no MBR/legacy. After several missteps, I got
it to work perfectly. Here's the play-by-play description:

Subject: Linux System calls sheet
Message-ID: <CAE7jHC9foJ8zaoN+R27ujaCYL7s=+nJsvf+AGueCxRmrEwWy2w@mail.gmail.com>

For better compression of Linux systems calls I've made wiki sheet of them:

https://en.wikibooks.org/wiki/The_Linux_Kernel/Syscalls

Motivation: There is about 400 systems calls. Man pages describe
groups of system calls and have alphabetical list of them. It is good
enough for reference but is not enough for exploration and learning.
Also there is not enough correlation between header files and
semantics of syscalls.

To make more order in the issue I've created this page. I used grep,
ctags, regex and scripting to extract raw list of syscalls from the
kernel. Then I arranged them accordingly header files.
Finally I categorized syscalls to fit the sheet in wiki.

The categorization is not ideal. Also there still is some
inconsistency. You are welcome to review, fix and update.

Thank you
