Authentication Failed for 8.04 LTS Upgrade

[DaddyUnit]

New Ubuntu/Linux user here


Update manager says "New distribution release '8.04' is available. I click "Upgrade"

A window pops up with release notes. I click "Upgrade"

A window pops up "Authentication failed. Authenticating the upgrade failed. There may be a problem with the network or with the server"

Any help would be appreciated.

Check your connection. Remove all third parties from your /etc/apt/sources.list

Thanks for the response.

Network connection is good (I can get here).

Most everything in /etc/apt/sources.list is commented out. The only two lines that are not commented out are:

deb http://archive.ubuntu.com/ubuntu/ gutsy main universe restricted multiverse
deb-src http://archive.ubuntu.com/ubuntu/ gutsy universe main multiverse restricted #Added by software-properties

From what version are you trying to update?

[DaddyUnit]

Thanks for trying to help me out. I finally downloaded the alternate disk and upgraded from the CD. I'm somewhat concerned about my ability to perform future updates/upgrades (i.e. it would be nice to know why this didn't work), but I'm over the crisis for now. I was upgrading from 7.10 by the way. Thanks again.

You are welcome. Good luck.

From what version are you trying to update?
I am having same problem. I am trying to upgrade from v7.10 to v8.04. Same error message. I use an apt-cacher server (by including /etc/apt/apt.conf.d/01proxy. But I renamed that file, restarted and still get the same error.

My sources.list on this machine:

Strange thing is... I did this a month or so ago on several nearly identical machines w/o problems. I held off doing this one till now to have a v7.10 machine still up and because this one is a Samba server (but so is one other of the upgraded machines).

If I go into Synaptic PM and do a reload it gets to 'downloading file 15 of 21' and hangs there. Is this indicative of one of the servers really being down?

[Skip Da Shu]

some dayes later... still occurs,no change

You know that you have to have your Gutsy fully updated before attempting an upgrade?

[Skip Da Shu]

You know that you have to have your Gutsy fully updated before attempting an upgrade?

Yes, update manager finds no pending updates for v7.10

[Pumalite]

Have you tried upgrading with the Alternate CD?

[Skip Da Shu]

Have you tried upgrading with the Alternate CD?

Nope, Anything tricky about doing that? or just plug, select, play?

[Skip Da Shu]

Have you tried upgrading with the Alternate CD?

Downloaded and burnt a good CD of it... can you point me to some instructions on how to do it from this CD?

That was just the ticket... Thanx much, machine up and crunching BOINC, samba serving the 'backups' drive, being the alternate 'browser list maintainer' and all under v8.04 as I type.

SOLVED for me anyway

[Pumalite]

You are welcome. Good luck.
