Thread: How can I rollback my upgrades?

hello,

i've done 'aptitude safe-upgrade' in ubuntu jaunty, after rebooted , no longer able access raid5 array (external sata via highpoint rocketraid card).

suspect it's related kernel upgrade below (from /var/log/aptitude):

aptitude 0.4.11.11: log report

how can rollback upgrades above?

thank

kernels not removed after upgrade, can boot old kernel, unless minor revision upgrade.

code:

dpkg -l | grep linux-image

this list installed kernels. if there 1 kernel listed, might have minor revision upgrade.

[upgrade] linux-image-2.6.31-12-generic 2.6.31-12.40 -> 2.6.31-12.41

if see upgrades these:

[upgrade] linux-image-generic 2.6.31.11.22 -> 2.6.31.12.23

-11 kernel present , can boot one.

if don't have other kernels expect running 1 can 1 of following things:

code:

aptitude search linux-image

and install kernel , boot one:

code:

p   linux-image-2.6.28-11-generic   - linux kernel image version 2.6.28 on x p   linux-image-2.6.28-13-generic   - linux kernel image version 2.6.28 on x p   linux-image-2.6.28-14-generic   - linux kernel image version 2.6.28 on x p   linux-image-2.6.28-15-generic   - linux kernel image version 2.6.28 on x

install 1 of these or..

run apt-cache policy linux-image-generic , see if there version available in main repos, because upgrades -updates, force re-installation of kernel.
jaunty (i'm doing on karmic install, you'll see installed kernel not available you).

code:

linux-image-generic:   installed: 2.6.31.12.23   candidate: 2.6.31.12.23   version table:  *** 2.6.31.12.23 0         100 /var/lib/dpkg/status      2.6.28.15.20 0         550 http://security.ubuntu.com jaunty-security/main packages         550 http://nl.archive.ubuntu.com jaunty-updates/main packages      2.6.28.11.15 0         550 http://nl.archive.ubuntu.com jaunty/main packages

so install 2.6.28.11.15 version of linux-image-generic package

code:

# remove -s, simulate option sudo aptitude -s install  linux-image-generic=2.6.28.11.15 reading package lists... done building dependency tree reading state information... done reading extended state information initializing package states... done following packages downgraded:   linux-image-generic following new packages installed:   linux-image-2.6.28-11-generic 0 packages upgraded, 1 newly installed, 1 downgraded, 0 remove , 8 not upgraded. need 24.6mb of archives. after unpacking 95.7mb used. want continue? [y/n/?] y download/install/remove packages.

after need remove old kernel:

code:

rmkernel () {         local cur_kernel=$(uname -r|sed 's/-*[a-z]//g'|sed 's/-386//g')         local kernel_pkg="linux-(image|headers|ubuntu-modules|restricted-modules)"         local meta_pkg="${kernel_pkg}-(generic|i386|server|common|rt|xen|ec2)"         sudo aptitude purge $(dpkg -l | egrep $kernel_pkg | egrep -v "${cur_kernel}|${meta_pkg}" | awk '{print $2}')         purge_pkg }

and need pin linux-image-generic package:

code:

pkg2pin () {         [ -z "$1" ] && return         local pkg         local msg         msg="$(date +'%y%m%d:%h%m%s')"         pkg in $@                         pkg=$(dpkg -l "$pkg" 2>/dev/null)                 [ $? -ne 0 ] && continue                 pkg=$(echo -e "$pkg" | grep "^ii" |awk '{print $2" "$3}')                 echo -e "$pkg" | awk '{print "explanation: added on '$msg' pkg2pin or dpkg2pin\npackage: "$1"\npin: version "$2"\npin-priority: 1001\n"}'         done | sudo tee -a /etc/apt/preferences } dpkg2pin () {         [ -z "$1" ] && return         local pkg         pkg=$(dpkg -l | grep "^ii" |awk '{print $2}' | grep "$1")         [ $? -ne 0 ] && return         in $pkg                         pkg2pin $i         done }

put rmkernel, pkg2pin , dpkg2pin code in .bashrc , source bashrc file (source ~/.bashrc) , can run commands:

code:

rmkernel dpkg2pin linux-image-generic

now kernel not upgraded anymore, unless remove /etc/apt/preferences file.
