I'm not that great with Linux every time I touched the terminal I mess stuff. You can't teach an old dog new tricks perhaps.
Its the cost you have to pay, for independence & freedom, peace of mind, Its unavoidable.
These days everything requires research, age is no excuse, google, apple, microsoft etc don't care, we are just livestock to harvest data & taxes from & brainwash.
Life is a process of continually learning, all the way to the end. Though there are a lot of brain dead of all ages out there.
Thanks to the Net, all the info you need, & plenty of supportive people out there to help when you get stuck. Unless you have the money to pay someone to do it for you.
I dread the terminal, as a jack of all trades, I hack through it, mostly by copying & pasteing posted terminal lines to get the result I need. I recently ungraded to a windows os mini pc, it had an amd chip, & all the linux os lacked the wifi driver, The only user friendly os with all the drivers was kali, a hacking os. Not as good for me as mint, but took a few weeks to rid myself of windows, I was going to use kali as a temporary os, but its grown on me, & if it works why fix it.
Then my abs lite up. So I've been spending my evenings over the last 9 weeks, trying to reboot my abs module on my car, so all the brakes warning lights go off, (just from driving on a shingle road) & get my car road legal again.
The hardest part was trying to install a windows 7 on an old laptop so I can run Forscan ford auto diagnostic (no prog for linux) on my Nissan, thats actually a Mazda, (our crazy world), problem was missing drivers, but I found a workable lite version in the end that was so cut down its wasn't a win os any more, no code needed, then I had to lie to the diagnostic giving it a borrowed mazda part code so it would recognize my Mitsubishi ecu, to reboot my abs module & problem solved, no warning lights. Ok 9 weeks ago I could have spent a few 100$, gone to an auto electrician, but this was my 1st computer car (tempted to get my old analogue truck back on the road). So I didn't know what abs was (I learnt to drive before abs), let alone a compatible cheap diagnostic, so many out there & my car is an obscure model. If the ecu (pcm) had been broken, replacing it would cost $3k - $4k, I was looking at removing it and having to re-solder the pcb (the solder cracks causing a fault), which meant disconnecting the brake lines & bleeding with the ecu, thankfully a reboot so far has worked, so now I can relax when driving on shingle roads. Independent of expensive experts.
Only so many hours in a day, its a constant bargaining, depends on you hourly rate, pay someone or figure it out doing it yourself.
