Linux Kernel 5.9 Released! How to Install it in Ubuntu

Last updated: October 12, 2020

Linux Kernel 5.9 was released a day ago. Linus Torvalds announced that:

Ok, so I’ll be honest – I had hoped for quite a bit fewer changes this last week, but at the same time there doesn’t really seem to be anything particularly scary in here. It’s just more commits and more lines changed than I would have wished for.

The bulk of this is the networking fixes that I already mentioned as being pending in the rc8 release notes last weekend. In fact, about half the patch (and probably more of the number of commits) is from the networking stuff (both drivers and elsewhere).

…

Linux 5.9 features initial Intel Rocket Lake graphics, NVMe zoned namespaces (ZNS) support, 32-bit x86 Clang build support, initial support for Radeon RX 6000 “RDNA 2” graphics cards, and more.

How to Install Linux Kernel 5.9 in Ubuntu:

The mainline kernel packages for Linux 5.9 (64-bit) are now available for download at the link below:

Select generic for common system, and lowlatency for a low latency system (e.g. for recording audio):

linux-headers-5.9.0-xxxxxx_all.deb
linux-headers-5.9.0-xxx-generic(/lowlatency)_xxx_amd64.deb
linux-modules-5.9.0-xxx-generic(/lowlatency)_xxx_amd64.deb
linux-image-xxx-5.9.0-xxx-generic(/lowlatency)_xxx_amd64.deb

Alternatively you can download and install the kernel binaries via terminal commands ( open terminal via Ctrl+Alt+T):

cd /tmp/

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.9/amd64/linux-headers-5.9.0-050900_5.9.0-050900.202010112230_all.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.9/amd64/linux-headers-5.9.0-050900-generic_5.9.0-050900.202010112230_amd64.deb

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.9/amd64/linux-image-unsigned-5.9.0-050900-generic_5.9.0-050900.202010112230_amd64.deb

sudo dpkg -i *.deb

Once installed, restart your computer and enjoy!

Uninstall Linux Kernel 5.9:

Restart your machine and select boot with the previous kernel in boot menu ‘Grub2 -> Advanced Option for Ubuntu’. Then run command to remove Linux Kernel 5.9:

[Quick Tip] Drag and Drop Pasting File / Folder Path into Terminal

Last updated: April 24, 2024

Familiar with Linux commands? You may already know many tips and tricks that will save you a lot of time.

Here are some that I have been using for a long period of time, including Tab auto-completion, when you type something in Linux terminal and hit Tab, it auto-completes the command or file path, or outputs all possible options.

And Ctrl+Shift+V will do paste text to terminal instead of Ctrl+V. Without copying to the clipboard, you can simply select / highlight the text and use mouse middle-click to paste into terminal.

Today I found a new terminal tips that I didn’t know before. Thanks to the reddit, I’m going to share it with you by following steps.

1. Drag and drop file or folder to paste the path into terminal.

Just drag and drop a file or folder into terminal, and you’ll see the full path pasted with single quotes. It’s useful if there’s special character in file path or you just don’t want to type …

2. Drag and drop a selection of text into terminal.

You can also drag and drop a selection of text into terminal, so you don’t need to do copy and paste with context menu clicks or keyboard shortcuts.

A number of Python built-ins (range, tuple, set, frozenset, list, dict) are now sped up using PEP 590 vectorcall;
A number of Python modules (_abc, audioop, _bz2, _codecs, _contextvars, _crypt, _functools, _json, _locale, operator, resource, time, _weakref) now use multiphase initialization as defined by PEP 489;
A number of standard library modules (audioop, ast, grp, _hashlib, pwd, _posixsubprocess, random, select, struct, termios, zlib) are now using the stable ABI defined by PEP 384.

How to Install Python 3.9.0 in Ubuntu:

1.) Open terminal either by pressing Ctrl+Alt+T on keyboard, or by searching for ‘terminal’ from system application launcher.

When terminal opens, run command to add the “deadsnakes” team PPA:

3.) Once successfully installed, check your system Python versions (python –version):

4.) (NOT Recommended) To use Python 3.9 as the default python3, run commands:

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.8 1

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.9 2

For Ubuntu 16.04 and Ubuntu 18.04, replace python3.8 in the code with system’s default python3 version..
And you can then switch between the two Python3 versions via command:

sudo update-alternatives --config python3

NOTE: Due to known bug, terminal won’t open if you changed python3 symlink. An workaround is recreate a symlink via command (Replace python 3.8 with your system default python3 version):

sudo rm /usr/bin/python3; sudo ln -s python3.8 /usr/bin/python3

Uninstall:

To uninstall the Python3.9 packages, run command:

sudo apt remove --autoremove python3.9 python3.9-minimal
