I'm on AWS and despite being looged in as root, I can't edit /etc/sudoers
adduser houman
usermod -aG sudo houman
When I login as houman and try sudo ls:
[sudo] password for houman:
Any idea, why this is happening?
I have been doing this in all previous Ubuntu editions without an issue, but something has changed in Ubuntu 20.04.
sudo apt install iptables-persistent
iptables -A INPUT -p tcp -m tcp --dport 443 -j ACCEPT
...
debconf-set-selections <<< "iptables-persistent iptables-persistent/autosave_v4 boolean true"
debconf-set-selections <<< "iptables-persistent iptables-persistent/autosave_v6 boolean true"
dpkg-reconfigure iptables-persistent
Two things I have noticed
- Despite the settings above, I can't install it silently. I get this screen:
And despite clicking yes the file /etc/iptables/rules.v4is empty
*filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] COMMIT
- After a reboot, everything is set to the file above. So nothing is saved.
Any advise please?
ulogd2.service doesn't seem to work on Ubuntu 19.10.
When I do ls /run/ulog/ulogd.pid it finds nothing.
I think the file can't be generated.
When I do ls -lt /run it shows the correct access rights:

I have installed redis client (without the server) on one of my servers:
sudo apt install redis-tools
I would like to use redis-cli to connect to a central server where redis is installed.
But because I didn't install the server, there is no config file available at this path:
/etc/redis/redis.conf
Is there a way to create the config, so I don't have to use -h every time?
When I ssh into the server it says:
11 packages can be updated.
11 updates are security updates.
Then I verify that everything is installed:
canonical-livepatch status --verbose
And this is what I get:
client-version: 9.3.0
machine-id: xxx
machine-token: xxx

So there is nothing to apply? How about those 11 security updates then?

I have two ppa added to my Ubuntu 16.04 installation and would like to freeze the current release that I have thoroughly tested.
add-apt-repository ppa:certbot/certbot
add-apt-repository ppa:freeradius/stable-3.0
Is there any way to freeze the current version, so that future unattended upgrades don't get the latest which may break the production system?
This is how I have setup my unattended upgrades.
sed -r \
-e 's|^//Unattended-Upgrade::MinimalSteps "true";$|Unattended-Upgrade::MinimalSteps "true";|' \
-e 's|^//Unattended-Upgrade::Mail "root";$|Unattended-Upgrade::Mail "root";|' \
-e 's|^//Unattended-Upgrade::Automatic-Reboot "false";$|Unattended-Upgrade::Automatic-Reboot "true";|' \
-e 's|^//Unattended-Upgrade::Remove-Unused-Dependencies "false";|Unattended-Upgrade::Remove-Unused-Dependencies "true";|' \
-e 's|^//Unattended-Upgrade::Automatic-Reboot-Time "02:00";$|Unattended-Upgrade::Automatic-Reboot-Time "03:00";|' \
-i /etc/apt/apt.conf.d/50unattended-upgrades
echo 'APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Download-Upgradeable-Packages "1";
APT::Periodic::AutocleanInterval "7";
APT::Periodic::Unattended-Upgrade "1";
' > /etc/apt/apt.conf.d/10periodic
service unattended-upgrades restart
Ideally, I could test this first on a test system, and when I'm sure that it all works, I could unfreeze the ppa on production to upgrade to the latest and then freeze it again.
Is this possible?
Tried sudo apt-get install postgresql-9.4 but it doesn't find it.
How can I install this version?
On Ubuntu 14.04 I have done this to get the latest postgres:
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt/ $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
sudo apt-get upgrade
Then I installed version 9.4:
sudo apt-get install postgresql-9.4
However it seems I have now three versions:
sudo service postgresql stop
* Stopping PostgreSQL 9.3 database server [ OK ]
* Stopping PostgreSQL 9.4 database server [ OK ]
* Stopping PostgreSQL 9.5 database server [ OK ]
How can I keep only 9.4 and uninstall the other ones? Thanks
UPDATE:
As suggested in comments I have uninstalled 9.3 and 9.5.
But when I do this:
sudo service postgresql status
9.3/main (port 5432): down
9.4/main (port 5434): online
9.5/main (port 5433): down
So far so good, but when I switch to postgres:
sudo su postgres
and do a psql, I get an error:
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
I just followed these instructions http://www.techrepublic.com/blog/ope...on-ubuntu/4343 on a fresh installed Ubuntu 13.04 and it crashed during installation with the following error message:
Code:

I am trying to connect to a PPTP VPN server. The same config works fine in Windows but fails in Ubuntu 12.10. It must be some configuration issue.
sudo pptpsetup --create MYVPN --server xxx.xxx.xxx.xxx --username username --password password
Everything is setup correctly. But then when I try to actually run the VPN I get this:
$ sudo pppd call MYVPN updetach

Connect: ppp1 <--> /dev/pts/2
LCP: timeout sending Config-Requests
Connection terminated.

When I do this for more details:

Why is it not connecting? It works fine from Windows, so it must be something with Ubuntu 12.10 settings...

I have messed around with the template1 database, and would like to reset everything as it was.
Hence I have done a sudo apt-get purge postgresql
However the next time I reinstalled it, the databases are still there. Why? Nothing has been reset.
I am new to Ubuntu 12.04 and am trying to install Persian language support for a friend. I have been googleing for an hour and can't find a tutorial to explain this.
I have added additional language support and added Persian.
What is the next step? How can I type in Persian in LibreWriter please?
Many Thanks
I had to uninstall phpmyadmin from the production server and googled for it and used this:
sudo dpkg -P phpmyadmin
Well, this worked fine, but it seems everyone else on Ubuntu is using a purge instead
sudo apt-get purge phpmyadmin
Have I done anything wrong? Any consequences I should be aware of (it is my production server after all) Are all bits of the phpmyadmin really uninstalled through dpkg -P?
I have installed Eclipse 3.7.2 via PPA and subsequently I have clicked on Add New Software and the link to 64Bit Aptana studio 3.
It found the plugin and installed it correctly.
Now when I startup the Eclipse I get this error:

I have installed Windows 7 today and right after installed Ubuntu 12.04 next to it.
Now after rebooting the machine, it goes right into Win7 without asking me anything at the boot menu which OS to load.
In windows I can see that the ubuntu partitions are still there.
Thanks
I am new to Ubuntu and really would like to replace Windows with it. One problem I am now running into is to make the second screen working.
I have an Optiplex 990, which comes with an internal Intel 2000 Graphic Card and an ASUS ATI Radeon HD 6570. Each graphic card is connected to one 24" monitor.
When I start Ubuntu 12.04 from USB stick, the boot menu shows on the Intel monitor. Then the Ubuntu....-loading-logo appears on the second Ati monitor. Then the actual Ubuntu workspace loads on the Intel monitor again and the ATI monitor goes into power save mode.
Doing this I get:
lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Turks [Radeon HD 6570]
Therefore the screen you see here is only the intel driven one. The ATi one is forgotten.
I ended up installing the ATI driver from their website. and went through the steps as described here:
After installing it, I still get the following:
ubuntu@ubuntu:~/Downloads$ fglrxinfo
display: :0 screen: 0
OpenGL vendor string: Tungsten Graphics, Inc
OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Desktop
OpenGL version string: 1.4 (3.0 Mesa 8.0.2)
Which is expected, as my ATI connected screen is disabled.
