Useful video! Thank you!

[@send2gl]

That was useful. Use systemctl on occasions but not too familiar with the service names. The journalctl I havent used but shall give it a try.

Hey man. Could you give a detailed video about how to install Ubunto 20.04 onto a GPT external USB SSD?
I have a laptop with the SSD soldered to the board. So despite being easy to remove the windows drive...I cannot >_>
I have been reading how to pages for days and I kind of understand the basic idea of it. But I get stumped when I move into the installation area "Something Else". I REALLY DO NOT want the ubuntu to install ANYTHING dual boot or overwrite my windows partitions. I think it should look something like this, but not 100% certain:
Gparted, set the external drive to GPT(my system uses uefi/gpt) -> in the Something Else part of the install process I find the SDB(the target drive) free space --> anddd......there are a bunch of pages saying to set this up a bunch of ways. One way I think is to setup a efi partition with 500MB, a Root(no idea how much), a SWAP at double the RAM(totally fine) and then dump the rest into a /HOME?
Oh and what the heck does the drop menu below achieve(boot from "Target External Drive name/title") when I direct it at the target external drive? Does this make a redundant efi partition or something? IRead a few pages that say Ubuntu will overwrite parts of the boot for windows which would greatly upset me. I don't want the installation to touch my windows OS at all.
So as of now I use a Live Ubuntu on an external SSD with 400GB of persistant space. But the only difference I can see is the lack of proper password protection of certain linux areas and install uninstall functions. Everything else seems to run as normal. Personally I can wipe the driv all day anytime anything bad happens to it. It is only a pocket OS for web surfing out in public areas. But I am a little curious if a full Ubuntu install carries anything more beyond the password stuff. I think the Live version runs mostly in the RAM over the Full install. But again, web surfing isn't going to matter much in this regard either.
Thoughts, help? If you do respond, thanks in advance :D

hello Linode :). Just a bit of feedback: could we get a seperate playlist on the basics with the playlist in order. In other words, I'd would be nice if we could have a playlist where videos are sorted in order as when you would start from scratch (i.e. creating server, ssh keys, admin commands, etc.)

[@AkamaiDeveloper]

Thanks for the feedback, that sounds helpful. We'll give it a shot!

[@rostranj2504]

thanks for the response!

[@pivot3india]

if I have logrotate configured to make a log file every few weeks, will journalctl be able to read from all the files ?

[@rasendrakumarnath650]
