zramswap snag

[rjackson1969]

I'm not positive what initiated this problem but now anytime I try to upgrade or download updates or run my synaptic package manager or whatever in the terminal, I seem to run into this and it snags and hangs right there.

(Reading database ... 217483 files and directories currently installed.)
Preparing to replace zramswap-enabler 0.2.1-0~19~precise1 (using .../zramswap-enabler_0.2.1-0~20~precise1_all.deb) ...

Last thing I did before this was to install Miro. When I try to uninstall Miro, it snags there too. When I try to upgrade Miro to a newer version, it snags there.

Any ideas on how to repair?

The only way out of the hang is a reboot to force quit.

I have the exact same error.

I'm getting the same issue and I don't have Miro installed.

The way I got around the freezing of apt utilties was to kill off dpkg and then uninstall it, which gave me the freeze issue again. The second time trying to uninstall it worked like a charm.

I would uninstall it untill the zram folks can get it working properly.

sudo killall -9 dpkg

Any further attempts to use package utilties should ask you to run the following to fix the state in which you left dpkg.

sudo dpkg --configure -a

Then:

wajig purge zramswap-enabler

It'll still seem to get stuck. If you kill off dpkg again, from getting tired of waiting, make sure to run the purge command, just to make sure things are uninstalled.

Run thius again:

sudo dpkg --configure -a

Then maybe run autoremove to remove unnecessary deps.

Someone should report the issue to what ever dev runs the corresponding ppa. I don't remember which ppa corresponds, but suffice to say it's not part of a default Ubuntu install, nor is it supported.

UPDATE
It's ppa:shnatsel/zram

You can try this;

http://www.ubuntuupdates.org/package...se/zram-config

it is still buggy and hard to remove. It grabbed 4 GB of my SSD, and I was unable to change that despite using a number of utilities. It has not caused any serious problems up to now, but I can't see any use for it on my machine and I don't want to lose 4 GB of space on my SSD to it. I am rather put out that it was installed as a default and without asking me.

There is no evidence to suggest that it is any use at all on a SSD.

So, you an remove it using "Disks" utility. Just delete the swap partition on the SSD.

Update Manager got botched stalling zramswap-enabler update from zramswap-enabler_0.2.1-0~19~precise1_all.deb to 0~20.

Subsequently all this failed:
apt-get remove zramswap
apt-get install -f
apt-get autoclean
apt-get autoremove
synaptic
dpkg --configure -a

I then used the folowing long and fastidious method (overdetailed, newbie mode activated, beeing a newbie myself), to overcome this.

***********************************

pre-0 - Forgot this, I rebooted before doing this...

0 - Open a terminal:

0.1 - press simultaneously <control> <alt> <t>

or

0.2 - go through the menu for this step

1 - become root
sudo su <enter>
type_your_administrative_password <enter>

2 - stop zramswap-enabler, type
/etc/init.d/zramswap stop <enter>

3 - remove zramswap-enabler startup service
update-rc.d -f zramswap remove <enter>

4 - Remove zramswap-enabler files, choose one of of the following two options:

4.1 - YOU ASSUME, BY CHOOSING THIS OPTION, THAT YOU FULLY UNDERTAND ALL ITS IMPLICATIONS; just remove all the zramswap* files, type
find / -type f -name "zramswap*" -exec rm -f {} \; <enter>

or

4.2 - ask for permission for every removal, type
find / -type f -name "zramswap*" -exec rm -i {} \; <enter>

5 - To be on the safe side

5.1 - type
apt-get autoremove <enter>

5.2 - type
apt-get autoclean <enter>

5.3 - probably not needed, but just in case, type
apt-get remove zramswap-enabler <enter>

6 - close terminal

7 - reboot

Good luck.

Took a few tries but it seems to be working right now. Thanks.

I did it with sudo dpkg -r --force-remove-reinstreq zramswap-enabler it threw an error, then went xkill on the terminal. Rebooted

sudo apt-get update
sudo apt-get upgrade -f
sudo dist-upgrade -f

Now things are back working again and I can update my system.

Thanks a lot hypermodern! Your solution worked very fine.
