Thread: do-release-upgrade error from 11.04 to 11.10

i have ubuntu 11.04 server. original install on box 11.10. past do-release-upgrade 11.04 went fine. "apt-get" , "aptitude" updates/upgrades fine no errors. on do-release-upgrade 11.10... errors out.

code:

$ sudo do-release-upgrade traceback (most recent call last) file "/usr/bin/do-release-upgrade", line 5, in <module>     import apt file "//usr/lib/python2.7/dist-packages/apt/_init_.py, line 24, in <module>     apt.package import package file "/usr/lib/python2.7/dist-packages/apt/package.py", line 27, in <module>     import subprocess file "/usr/lib/python2.7/subprocess.py", line 432, in <module>     import pickle eoferror: eof read object expected.

code:

hardware:  hp nrl-ls mobo,        serverworks chipset       3.5gb ecc ram       adaptec 29160 scsi controller       lsi megaraid series 493 elite 1600 scsi controller 2 pata's internal 11 scsi's external         gateway datastation ultra-11         raid 5...

another weird thing on box... shouldn't related, should mention in case- raid won't mount on boot (via adaptec nor lsi) mount manually without hitch after login, cli. mount via both adapters if slow down boot... said, don't think that's related, knows @ point. argh...

know might corrupted or missing can upgrade 11.10?

after week of fighting versions 10.10 through 12.04 alpha 1... install menu'ed selections , progress bars happen in tty1. terminal installation status , messages happen on tty4... errors start errors installing base system... trace main package not being downloaded.

after installer said configured network devices , gotten time internet... lied. using 12.04, came dialog saying missing non-free firmware network card. put unpacked tar ball on usb drive... still didn't find it.

so... threw in intel pci networkwork card. installed server 10.04.3. brought dialog asking if broadcom netxtreme or intel primary... selected intel , continued without problems... after installed linux-firmware-nonfree... , know, though package broadcom nic should using , should have been installed use it- had not been installed.

have servers 5 popular servers boards. has been 1 has comeuo install problem. (enough going reinstall ms server 2008 on it!)

solved or @ least found workaround, but-- figure common , popular server board supported ubuntu server, right? "would" think...

running now, turning in bug report on server edition 10.04 through 12.04 this...
