always if I try start do-release-upgrade ( equal with sudo or as root )
I got the message:



root@mbc-workstation:~# do-release-upgrade
Neue Veröffentlichungen von Ubuntu werden gesucht *(German means: Searching For new releases)*
Failed to connect to http://changelogs.ubuntu.com/meta-release. Check your Internet connection or proxy settings
No new version found.


There should be no problem with the connection to the internet, because I can ping changelogs.ubuntu.com successfully:



root@mbc-workstation:~#ping changelogs.ubuntu.com 
PING changelogs.ubuntu.com (91.189.95.15) 56(84) bytes of data. 
64 bytes from rubay.canonical.com (91.189.95.15): icmp_seq=1 ttl=53 time=18.5ms


and I also can reach the http://changelogs.ubuntu.com/meta-release page with any browser.



Any idea will be appreciated.



Thanks a lot

  • Is there any other possibility to upgrade without performing a fresh install?

  • Did you try using muon or even update-manager [the gnome updater]?

  • In the past I've updated by just updating all the /etc/apt/source.list lines to be the new release, so if it says "artful" change it to "bionic" (some PPAs won't have an update so you need to check with the non Ubuntu/Canonical ones). Then just run an apt update and done sudo apt dist-upgrade (or apt-get as it was then). But I wouldn't recommend it and can't guarantee it won't break or leave you unbootable, YMMV.

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...
