You might want to check the errata for the packages your scanning tools complained about. Rhel will keep stable versions at the same release version, but backport security fixes in.

Many security scanners are stupid about this.

Since it is rhel, you have a support contract, right? What do they say?

One may just be a symlink to the other depending on your distro. For shebang lines, I’d probably go with /bin/zsh

How are you trying to install things? Use the graphical package manager or apt. Don’t just try to download things from wherever.

Also, maybe try Linux Mint (Cinnamon Edition) instead of Ubuntu. Things there “just work”, and the UI is more similar to what you are used to with windows.

The new NIST guidance is to have something long. Special characters don’t matter. So a good passphrase that you can remember > short line noise. NIST also recommends against constant password rotation, but to instead audit for dictionary attacks. See also: https://www.netsec.news/summary-of-the-nist-password-recommendations-for-2021/

Yes, it is bad programming. Of course, on the backend you must never store passwords in the clear. You should never grow your own hashing algorithm.

For a disc you need a new fork if it does not already have mounts for the disc calipers. By “new set of gears” I assume rear cassette. You will need a chain whip and a cassette tool. Keep in mind that all drivetrain parts tend to wear together. Its important to swap your chain when it starts to wear. I just do mine every spring to be safe. If it’s been awhile, you’ll need new chaingring(s), casette, and chain. After a longer time, it’s good to replace the pulleys in the rear derailleur too.

But like others have said, with this amount of effort, just get another bike.

Linux/Cups. Postscript. Laser. Have never had a problem. Printers not working is a “put the logic in the Windoze driver” problem vs telling a good printer “Print this”.

As with all things infosec (and life in general), best practice is to not get yourself into the mess in the first place vs. trying to clean up the mess later. You should have already not had personal data “in the cloud” and should have been using unique identifiers and authentication for every service that you use.

Mint has simplescan. Did you try that?

Rutter’s peanut butter chocolate milk ftw!
