How to install autojump for Fish on Ubuntu

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!

GSConnect doesn’t mount my phone on Manjaro Gnome, this is the solution

Hi there! I am using the Gnome shell extension GSConnect on Manjaro Gnome to share files from my phone to my laptop. There is an option called “Mount” that initially didn’t work on Manjaro but I found a solution and it now works like a charm!

All you need to do is to edit the file /etc/ssh/ssh_config

sudo vim /etc/ssh/ssh_config

and add to the end of the file the following:


Host 192.168.*.*
HostKeyAlgorithms +ssh-rsa

Install docker and docker-compose on Linux Mint 20.3

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>

Fingerprint reader 0a5c:5843 Broadcom Corp. 58200 Ubuntu / Linux mint driver install

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

Accessing Samba on Manjaro: failed to retrieve share list from server

A few days ago I got my shiny new StarBook Mk V and installed Manjaro on it for the very first time. I have no prior experience neither with Arch-based distros not rolling releases. Anyway, soon after I installed it I realized that I can’t access my homemade NAS server over Samba. I have a samba network at home with a mix of Linux (Linux Mint, Manjaro) and Windows 10 (don’t judge me) computers. Samba has always worked well to connect to each other. But now, when opening smb://192.168.1.6 in Gnome file manager I get this error: Failed to retrieve share list from server: Invalid argument

After quick duckling I found the solution: everything you need to do is to add these two lines in the global section of /etc/samba/smb.conf file on the server

client min protocol = CORE
server min protocol = CORE

and then restart it:

sudo service smbd restart

Voila!

P.S. The solution is based on the original post on the Manjaro forums here.

PHP Warning: PHP Startup: mcrypt: Unable to initialize module

If you have installed multiple PHP versions using PPA maintained by Ondrej Surý 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

Install the latest versions of Vagrant and VirtualBox on Linux Mint 19.2

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.

Batch rename files with Cyrillic filenames to Latin ones (transliterate file names)

If you have a bunch of files with Cyrillic file names, there is a chance that some old devices such as TV embedded players, car audio systems, mp3 players may not recognize them or fail to read. The quick and dirty solution is to rename these files to Latin only characters. In order to save some time I use this handy bash script. It works flawlessly on both Windows (Git Bash) and native Linux systems. Continue reading

This machine ID is already enabled with a different key or is non-unique

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.

Vagrant: Authentication failure. Retrying…

I recently bought a newer laptop. It had Windows 8 preinstalled which I wiped immediately in order to install Linux Mint 19.1 and started to migrate data from my old machine. I packaged my vagrant box and transferred it to the new machine. Once imported the box back and issued vagrant up command I was surprised by the following errors:
