I tried to upgrade my Ubuntu to the recently released 18.04 LTS from the 16.04 version. After the install when I powered it off and then on, I was taken to the GRUB screen instead of the normal booting. I tried to follow the steps in the this answer here: GNU GRUB Terminal - Instead of Ubuntu login screen



Here's a run down of what I have typed:




set pager=1

set root=(hd0, 1)

linux /boot/vmlinuz-4.15.0-20-generic root=/dev/sda1

initrd /boot/initrd.img-4.13.0-32-generic

boot




That showed me some error in initramfs shell like




ALERT /dev/sda1 does not exit dropping to shell




I realised that my root system location might not be in sda1. So, I tried the steps again with different sda's. When I am doing that I now get this error:




error: disk `(hd0, ' not found.




Please help.




boot grub2 18.04

  • Don't do these lines randomly you can use command ls /dev/sda1,2.. and verfify which one is root.

  • I'm sorry I didn't get you @Debian_yadav. How do I verify my root again? Typing exactly ls /dev/sda1,2.. gives an invalid file name error. I'm sorry for asking such a naive question :/

  • By 1,2... I meant try /dev/sda1 then /dev/sda2 that is a variable entry. And it not solution it is to improve your method of searching.

Which professions warranted travel in Medieval times?

Image
Clash Royale CLAN TAG #URR8PPP up vote 54 down vote favorite 15 I'm trying to come up with characters whose backgrounds allow them to have homes, histories, and skills, but will still enable or encourage them to travel in a typical medieval setting. I've never really liked "Adventurer" as a job, and would like my story to have a kind of unlikely-hero vibe. besides the common "Traveling merchant", what kinds of artisans or professionals in fantasy would have a reason to move around the world (or at least visit other settlements)? First time posting, so let me know what to improve. Thanks! EDIT: When I say traveling, I was thinking someone who spends multiple days/weeks/months away from their place of origin as they go elsewhere for their business, or to gather materials for it. medieval travel share | improve this question edited Aug 1 at 15:16 asked Aug 1 at 15:07 Julia Witham 279 2 7 11 Please ...

How do so many people here on Academia.SE, and in general, afford lavish higher education programs?

Image
Clash Royale CLAN TAG #URR8PPP up vote 45 down vote favorite 7 I graduated last year with a BS in Computer Science. I do not come from a particularly wealthy family, (very low middle class), and was only able to afford my education via school loans/scholarships and working low-wage jobs, with no support from my family or anyone else. I realize some scholarship/loan programs extend into grad school. But I don't think those cover all costs. Now I'm lucky enough to have a decent-paying salary in industry, along with benefits and living on my own, and I'm thinking one day (sooner rather than later) I'd like to try my hand at research or continue my degree, but these things cost money, in addition to my regular living expenses. I read posts here often about academic people being in positions of choosing between these crazy research grad programs, some in Japan, or Ireland (while they currently live in the U.S./U.K.) then moving around between countries/universit...
