Update Manager got stuck (but not frozen) while installing downloaded updates. What should I do?
Ideally you should skip configuring flashplugin-installer
and reconfigure it when you have a stable connection.
You can kill the download processs to proceed without configuring the package, mostly it is wget
, or sometimes curl
, but here it seems that it downloads via debconf
.
To abort the transaction, you can kill dpkg
,
sudo killall dpkg
Then remove the lock,
sudo rm /var/cache/apt/archives/lock
sudo rm /var/lib/dpkg/lock
Then when you have a stable connection, execute,
sudo apt-get -f install
sudo dpkg --configure -a
Here's what I did.
First I found the stuck process (number 19123 in my case):
> pstree -p
├─gksu(7266)─┬─precise(9756)
│ ├─precise(9757)─┬dpkg(24158)─update-notifier(19121)─package-data-do(19123)
│ │ └{precise}(9759)
Then I helped out with bug report: https://bugs.launchpad.net/ubuntu/+source/flashplugin-nonfree/+bug/1243090 . By running "sudo gdb" then "attach 19123" and "bt" to create a backtrace. The backtrace helps the volunteers determine what's wrong.
Finally I used "sudo kill 19123" and received error message "Could not install 'update-notifier-common'" "subprocess installed post-installation script returned error exit status 143".
The rest of the install then completed without incident.
