GPaste is an open-source clipboard management tool for Linux-based operating systems. Clipboard managers like GPaste allow users to manage and access a history of items they have copied to the clipboard, enabling them to easily paste previously copied content.
Sadly, there are binary packages available but you can compile it and install it manually.
Autojump is a tool that can be used to jump around in the shell to frequently used directories by typing just a part of their name. It is typically aliased to j. Autojump is available as a package in the Ubuntu repositories, but it needs manual intervention to be available in the fish shell.
1. Install autojump
sudo apt install autojump
2. Source the autojump.fish file in your fish configuration, by opening the file ~/.config/fish/config.fish in an editor and adding these lines:
begin
set --local AUTOJUMP_PATH /usr/share/autojump/autojump.fish
if test -e $AUTOJUMP_PATH
source $AUTOJUMP_PATH
end
end
3. Add j shortcut command to fish creating a new file ~/.config/fish/functions/j.fishwith the following content:
function j
set new_path (autojump $argv)
if test -d "$new_path"
echo $new_path
cd "$new_path"
else
echo "autojump: directory '$argv' not found"
echo "Try \`autojump --help\` for more information."
false
end
end
Usage examples:
– j Down – changes to my Downloads folder
– j work – changes to my workspace folder
Enjoy!
Issue the following commands in the terminal, one by one and you are ready to go! It’s simple as that 🙂
#docker setup echo "deb [arch=amd64] https://download.docker.com/linux/ubuntu focal stable" | sudo tee /etc/apt/sources.list.d/docker.list curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - sudo apt update sudo apt install docker-ce docker-ce-cli containerd.io pigz #execution permission sudo usermod -aG docker $USER #docker compose sudo curl -L "https://github.com/docker/compose/releases/download/2.2.3/docker-compose-$(uname -s | tr '[:upper:]' '[:lower:]')-$(uname -m)" -o /usr/local/bin/docker-compose sudo chmod +x /usr/local/bin/docker-compose</pre>
First, we need to checkout the following repo containing the driver:
git clone https://git.launchpad.net/~oem-solutions-engineers/libfprint-2-tod1-broadcom/+git/libfprint-2-tod1-broadcom/
Then go into the cloned folder and issue the following commands:
sudo sh install.sh python3 debian/update-fw.py
You may need to restart the laptop in order the changes to be applied.
Finally, enable fingerprint login using the following command:
sudo pam-auth-update
If you have installed multiple PHP versions using PPA maintained by Ondrej SurĂ˝ you may end up with the following error message:
PHP Warning: PHP Startup: mcrypt: Unable to initialize module
Module compiled with module API=20190902
PHP compiled with module API=20170718
This is caused by a misconfiguration: the php.ini file is pointing to the latest version of mcrypt instead of the one compiled for PHP 7.2. To fix that you have to correct the path to the extension. Open the file for editing:
sudo vi /etc/php/7.2/cli/conf.d/mcrypt.ini
and replace extension=/usr/lib/php/20190902/mcrypt.so with extension=/usr/lib/php/20170718/mcrypt.so. Do the same for /etc/php/7.2/fpm/conf.d/mcrypt.ini file.
If you have the module mcrypt.so listed in /etc/php/7.2/cli/php.ini or /etc/php/7.2/fpm/php.ini – delete it to avoid “PHP Warning: Module ‘mcrypt’ already loaded in Unknown on line 0” error
I use Linux Mint 19.2 as daily driver on my ThinkPad L480. This step by step tutorial will guide you through the process of getting the latest versions of VirtualBox and Vagrant instead of the outdated versions available in the official Ubuntu repositories.
VirtualBox and Vagrant receive updates on Linux much often than the repositories update. If you want to consistently get these updates when they become available, you’ll want to add VirtualBox and Vagrant repository to your system. This will allow you to get notified for new versions and update trough Linux Mint Update Manager and apt.
I have purchased new VPS and I wanted to enable Ubuntu live patch service for it. Unfortunately, the command canonical-livepatch enable [TOKEN] failed with this ugly error message:
This machine ID is already enabled with a different key or is non-unique.
Either “sudo canonical-livepatch disable” on the other machine, or regenerate a
unique /etc/machine-id on this machine with
“sudo rm /etc/machine-id /var/lib/dbus/machine-id && sudo systemd-machine-id-setup” :
{“error”: “Conflicting machine-id”}
I thought to myself “Ok, let’s try the suggested solution”. What I did was to backup the file /etc/machine-id, than delete it and run suggested systemd command. I was surprised to see the newly generated UUID was the same! Consulting with man page of systemd-machine-id-setup command revealed that “If run inside a KVM virtual machine and a UUID is configured (via the -uuid option), this UUID is used to initialize the machine ID. The caller must ensure that the UUID passed is sufficiently unique and is different for every booted instance of the VM.”. Obviously, my new VPS provider did not ensure that and somebody else has the same machine ID on his/her VPS and enabled Ubuntu live patch for it.
I have a Dell Latitude E5430 running Linux Mint 19 Tara. In Cinnamon, my function keys for brightness work correctly, but that was not the case with i3wm session. My first bet was to bind shortcuts executing xbacklight command but it doesn’t work because of this bug. So, I started to research for workaround and I found brightlight – “a program that can get and
set the screen backlight brightness on Linux systems using the kernel sysfs
interface.”. Sounds perfect but there are no prebuild binaries so you need to do it by yourself. The following steps are short guide how to build and install brightlight on Ubuntu and Ubuntu derivatives.
First, you will need to install PEAR via apt-get to get the necessary package and distribution system that both PEAR and PECL use. From a shell prompt enter:
sudo apt-get install php-pear
You will be prompted to confirm the install. Just press “y” and enter. If all goes well you should see it download and install the php-pear package.
Now you will need to install the php-dev package to get the necessary PHP7 source files to compile additional modules. Enter the following from a shell prompt:
sudo apt-get install php-dev
If you do not install the php-dev package and try to install a PECL extension using “pear install”, you will get the following error:
sh: phpize: not found
ERROR: `phpize’ failed
The PECL_HTTP extension requires an additional dependency package to be installed. You can probably skip this for other extensions:
sudo apt-get install libcurl4-openssl-dev
Now we are finally ready to actually install the extension. From a shell prompt enter following:
sudo pecl install ds
The installer may ask you about some specific options for the extension you are installing. Just accept the defaults and go ahead.
Once the install is complete, it’s time to enable the extension.
First, edit the following file (create it if it does not exist already):
sudo vi /etc/php/7.0/mods-available/ds.ini
and change it’s contents to:
; configuration for php ds module ; priority=30 extension=ds.so
Than check and remove any symbolic links to 20-ds.ini file, such as:
sudo rm /etc/php/7.0/fpm/conf.d/20-ds.ini sudo rm /etc/php7.0/apache2/conf.d/20-ds.ini sudo rm /etc/php7.0/cli/conf.d/20-ds.ini
You need to remove above listed symlinks because of bug: there is hard dependency on the json extension. DS extension shouldn’t try to implement JsonSerializable if the json extension is not loaded, but actually do it and it will complain with exception if it is not found:
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/ds.so' - /usr/lib/php/20151012/ds.so: undefined symbol: php_json_serializable_ce in Unknown on line 0
That’s why we removed 20-ds.ini symlinks and specified ds.so to load after json is already enabled.
Now, disable and then re-enable the extension:
sudo phpdismod ds sudo phpenmod ds
You may need to restart your HTTP server:
# If you are on apache sudo service apache2 restart # if you are on nginx sudo service nginx restart
