Motivating example: my Mint 20.3 distribution offers long-term support until April 2025, which matches the "standard support" offered for the upstream Ubuntu (20.04 "Jammy Jellyfish"). However, the...
When an upstream project stops supporting a version (e.g., Python stops supporting 3.8), the maintainers of the distribution do the job of supporting those components, applying security patches as ...
I want to switch hard drives. How do I migrate my root FS from the drive it's on, to the new one, so that everything is exactly as it is?
How to convert a json file to yaml? Technically json is already valid yaml, but I'm talking about the characteristic easy-to-read yaml formatting with indentation and minimal quotes.
dmidecode can do this. Here's an example output from my system: # dmidecode --type 2 Getting SMBIOS data from sysfs. SMBIOS 3.1.1 present. Handle 0x0002, DMI type 2, 15 bytes Base Board Info...
In Debian-based distributions, one can update the system with apt upgrade and cleanup unused dependencies with apt autoremove. Period. On Gentoo that is apparently not as straightforward. From G...
I don't know what these things are called exactly in the Linux world. But there is the concept of a drive in RAM, to write files onto and read them like it was any disk drive. There is also the c...
I figured this out myself. I needed to install the cnijfilter2 AUR package. Installing this package provided me with the correct PPD file (which was named canontr4500.pdd). How I figured this out:...
As a general rule of thumb, Debian is restrictive about installing during the initial installation what, according to the Debian Free Software Guidelines, is non-free software. That's why the inst...
POSIX defines Text file as A file that contains characters organized into zero or more lines. The lines do not contain NUL characters and none can exceed {LINE_MAX} bytes in length, inclu...
I have a RaspberyPi module, with USB connected to another module computer (as USB host) running Linux. The RasPi is configured as USB ethernet gadget. Once I boot the RasPi, and enter dmesg on th...
I plan to set up a Raspberry Pi to host some dockerized apps, for it to be accessible to the Internet through a remote proxy, and since I'm no sysadmin, I'm trying to come up with a suitable policy...
When exploring the commands from this answer to my previous question, I found that the ist of packages includes a lot that were automatically installed due to dependencies. Obviously I'm interested...
How do I get the URL of the remote repository that pacman uses to download packages? I know that I can tell pacman which server to use by editing /etc/pacman.d/mirrorlist. But in my case, all of t...
****Since upgrading to Ubuntu 22.04 recently, immediately after a reboot I have WiFi to an internet hotspot as I did prior to upgrading. After suspend then resume, the network is no longer working...
A solution I often use (and which is ultimately a variation of the find-based approach in the answer by Canina) also uses find, but only prints a single . per file: find . -maxdepth 1 -type f -pri...
I do this occasionally. It is sometimes useful to compare file titles where they aren't fixed lengths. For example: 01 02 The Beatles The Rolling Stones Help Satisfaction .m...
You can use -Suw for that. I haven't actually tested it, but it should work according to the documentation. From man pacman (redactied/edited for clarity): UPGRADE OPTIONS (APPLY TO -S AND -U) ...
Question How do you specify underscores as Vim word boundaries when using vim mode in either bash or zsh? MWE w on this_word should place the cursor on the underscore. A second w should place th...
I run Windows games with Wine, and use bwrap to sandbox them. I've noticed that passing --unshare-net to disable the network breaks many, many games (they fail to start with no obvious error messag...
I use Wine to play Windows games. As is well known: Wine is not a sandbox Windows games are proprietary blobs and can contain malware Windows malware can potentially harm Linux through Wine ...
What do you want to find though? Is the + a quantifier, meaning you are looking for one or more b? Or are you looking for the literal string b+? If the latter, you don't need to escape at all and i...
As the error says, WSL doesn't boot using systemd in the same way a native Debian install does, so you can't use systemctl either. The answer is simply to use service instead, which doesn't rely on...
Here goes nothing. An Internet search shows an answer on AskUbuntu#1164, author aneesheep. The gist is to install ImageMagick (try package name imagemagick) and then use the convert utility: conv...
MySQL is not fully open source and maintained by a corporation which was at one time regarded as very evil (there are much worse ones now). Debian is trying to protect you from yourself by not lett...
