postgresql packages in the removal blacklist making it hard to upgrade

[Iggy]

I have got this pop-up error message while updating from Ubuntu version 11.04 to 11.10:

Could not calculate the upgrade

An unresolvable problem occurred while calculating the upgrade:
The package 'postgresql-plperl-8.4' is marked for removal but it is in the removal blacklist.

 This can be caused by:
 * Upgrading to a pre-release version of Ubuntu
 * Running the current pre-release version of Ubuntu
 * Unofficial software packages not provided by Ubuntu

If none of this applies, then please report this bug using the command 'ubuntu-bug update-manager' in a terminal.

Status changed to 'Confirmed' because the bug affects multiple users.

[Deon Bennett (deonsed)]

I received the same error but I am running lucid 10.04 LTS. Trying to upgrade to 12.04

[Brian Murray (brian-murray)]

postgresql packages are listed in the removal_blacklist.cfg used by update-manager / ubuntu-release-upgrader because of bug 871893, where upon upgrade people were unable to access their databases.

[cfi (cfi)]

For those looking for this file, it is located at:
  /usr/share/ubuntu-release-upgrader/removal_blacklist.cfg

[cfi (cfi)]

Brian, if it is postgresql that is responsible, then commenting out that line from the removal_blacklist.cfg should help fix it.

After commenting out that one line, my blacklist now is:

# blacklist of packages that should never be removed
ubuntu-standard
ubuntu-minimal
ubuntu-desktop
kubuntu-desktop
xubuntu-desktop
lubuntu-desktop
# ubuntu-release-upgrader should not remove itself or update-manager
update-manager
update-manager-core
ubuntu-release-upgrader
# posgresql (LP: #871893)
#^postgresql-.*[0-9]\.[0-9].*
# the upgrade runs in it
^screen$
# unity
unity$
# gnome-session (LP: #946539)
gnome-session$

Still, the upgrader stops with the reported error message. Anyone any other suggestions?

[cfi (cfi)]

Also, the error message itself should be considered a bug:
(a) The error message yields three possible causes for the error without telling users which one applies
(b) For the third case (unsupported packages) it should list which packages are causing a dependency issue.

[Peter Fodrek (peter-fodrek)]

Thank you information about PostgreSQL told me to uninstall all packages depending on PostgreSQL and pgsql as well. This allowed me to start install process. Is it impossible to add information to possible causes " PostgreSQL packages installation may block upgrade"
Then there will be not such problems as my duplication of this bug as of bug 1310239.

Another recommedation is to add button for list of installed unsupported packages or button - uninstall unsported packages (my hurt some of your programs until package reinstall)

[Peter Chibunna (peterchibunna)]

Hi Peter.

Can you guide me through resolving this postgresql packages in the removal blacklist preventing upgrades?

I've had it persistently and my upgrading process is always hitched.

Thanks.

I had this trying to upgrade from 14.04 to 14.10, although I didn't get any indication of the package causing the problem - see #1406740.

I tried commenting out the postgresql line from removal_blacklist.cfg, like cfi mentioned, but similarly it didn't fix the problem for me.

Once I removed all the postgresql packages (server and client, plus the postgis stuff and as a knock-on some mapnik packages) the upgrade ran through successfully.

Sadly I didn't make a note of the packages I removed, but can probably work out a rough list of what they were if that's useful.

[Christopher Barrington-Leigh (cpbl)]

Similarly to amcewen: My system will not upgrade from 15.04 to 15.10.
My bug https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1509490 was marked a duplicate of this one, but the error message I get does not mention the problem. It does not mention postgres, though my machine is running postgres.

Commenting out lines in blacklist.cfg did not help. I restored them.

I tried

sudo apt-get remove postgresql

and that did not help. I reversed it.

I tried

sudo apt-get remove postgresql pgadmin3 postgresql-9.4-postgis-2.1

and that let me upgrade.

It seems this problem has been around for four years?! Maybe no one running postGIS can upgrade?

[Stéphane Charette (stephanecharette)]

From a comment I left earlier this year on another bug ticket which is now marked as a duplicate:

------------

Finally figured out why upgrades to 16.04 are prevented on many of my computers. The trick is to run this after a failed upgrade:

> cd /var/log/dist-upgrade/
> tail -100 main.log

In my case, this was the problem:

> 2016-06-09 15:48:07,039 DEBUG blacklist expr '^postgresql-.*[0-9]\.[0-9].*' matches 'postgresql-plperl-9.4'
> 2016-06-09 15:48:07,039 DEBUG The package 'postgresql-plperl-9.4' is marked for removal but it's in the removal blacklist
> 2016-06-09 15:48:12,070 ERROR Dist-upgrade failed: 'The package 'postgresql-plperl-9.4' is marked for removal but it is in the removal blacklist.'
> 2016-06-09 15:48:12,071 DEBUG abort called

So the solution for me was to remove that package:

> sudo apt-get remove postgresql-plperl-9.4

However, even knowing this, I still think this bug is valid. The upgrade process should provide more details when the upgrade refuses to run. For example, it could have either shown the name of the offending package, or perhaps even given me the option to remove it so the upgrade can proceed.

[Emmanuel Stapf [ES] (xumoqkn5d6or9iyw)]

actually doing

sudo apt-get remove postgres*

really went through all the various postgresql packages I had and tell me which one I had installed. After uninstalling them I was able to start the upgrade.

[Thierry Charlot (charlys29)]

i remove postgis extension for postgresqul and after upgrade start normally

sudo apt-get remove postgis

I saw this just now upgrading from fully up to date 14.04 to 16.04.

apt-get remove postgresql-9.3-postgis-2.1

was sufficient to fix it.

[Rene Schickbauer (rene-schickbauer)]

Removing pogresql extensions (plugins) only CHANGES the nature of the problem, instead of solving it!

If you remove the old postgis version, but it's used in one of the databases, programs like pg_upgradecluster break.

This means, now a complete restore from a database backup is needed, which is much slower and increases downtime by many hours.

[Jamie Nadeau (james2432)]

Also received this issue going from 14.04 to 16.04. This is very annoying that postgis extension blocks a full system upgrade. Not to mention that this bug is 4 years old and still not fixed!

[Ellis (ellisbjohns)]

Same issue here. Had to execute:
apt-get remove postgresql-9.3-postgis-2.1
a few times to solve the issue.

[Briancady413 (briancady413)]

I did
'sudo apt-get remove postgresql-9.3-postgis-2.1', then restarted, then attempted to upgrade from 14.04 to 16.04.1, but face the same issue again.

[Briancady413 (briancady413)]

I tried 'sudo apt-get remove postgis' as well as repeating 'sudo apt-get remove postgresql-9.3-postgis-2.1'. No luck. I've also eliminated many large unused programs - same thing.

[mschneider (wand3r3r)]

Upgrading from ubuntu 16.04 to 16.04.01 I had to uninstall all postgresql packages

Stephane Charette's 2016-07-25 comment #12 helped me immensely - thank you.

[isomorphismes (isomorphismes)]

I got sent here by the auto bug reporter. Trying to upgrade from 12.04 to 16 LTS

[Kevin_Traas (kevin-traas)]

Stephane Charette's 2016-07-25 comment #12 helped me.

I am attempting to upgrade 14.04.5 to 16.04.x.

Unlike others, I did not have a 'postgis' package installed. However, I do have postgresql-plperl-9.3 installed and, after removing this package, the upgrade proceeded normally.

# dpkg --get-selections | grep -i postg
postgresql install
postgresql-9.3 install
postgresql-client-9.3 install
postgresql-client-common install
postgresql-common install
postgresql-contrib-9.3 install
postgresql-plperl-9.3 install
postgresql-server-dev-9.3 install
# apt-get remove postgresql-plperl-9.3

[Torsten Hilbrich (torsten-hilbrich)]

Similar problem occurred to me when trying to update from 16.04 to 18.04. I had to uninstall the postgresql-plperl-9.5 package first. Then the update was startable.

[Jeff Lane  (bladernr)]

Please do not assign bugs to yourself and change the status, especially when those bugs are marked invalid.

[Billoir Romain (maz83)]

I'm surprised: 8 years later, the bug is still here.

I wanted to upgrade from 18.04 to 20.04 and faced the exact same issue caused by postgis.

What worked for me were to remove postgis, do the upgrade, and re-install postgis:

sudo apt remove postgresql-12-postgis-*

sudo do-release-upgrade

sudo apt install postgresql-12-postgis-3

[Yan-hoose (yan-hoose)]

Ran into this issue when attempting to upgrade from 19.10 to 20.04.

I had to remove postgresql-11-postgis-2.5 for the upgrade to work.

Really strange bug.

[Paul Schreiber (paulschreiber)]

Also ran into this issue when attempting to upgrade from 19.10 to 20.04.

After removing postgresql-10-postgis-2.4, I ran do-release-upgrade again and got this message:
   Please install all available updates for your release before upgrading.

I ran apt upgrade. It's now installing a lot of focal packages:

...snip...

It's 2020, and 4 years after reporting it (there https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1594355) I am once again facing this bug upgrading from 18.04 to 20.04 because of postgresql-11-postgis-3. When is someone going to have a look at it?

[LuisC (luiscardozocarreras)]

Same thing here. Trying to update from 19.10 to 20.04 and getting this error.

I know that I can solve by backing up my databases and removing all postgres related packages, but I supposed that the Release Upgrader should make everything "automagically".

[Flaburgan (flaburgan)]

No need to remove all postgres packages, removing postgis should be enough.

[Quinn Balazs (qbalazs)]

Fix released in Oneiric. This particular bug has been resolved. Future issues are not due to bug #871893, thus should be reported separately n

[Quinn Balazs (qbalazs)]

I'm trying to say that if you're still experiencing this issue and you have
updated past Oneiric (11.10) this is NOT the same bug. postgres was in the
removal blacklist due to Bug 871893. Fix released for 871893 in Oneiric
Updates. Therefore if it is in the removal blacklist again, it is a
different issue altogether, Do not keep adding reports to an invalid bug
from 2015 that was due to something now marked Fix Released. Please for the
love of dog, report a new bug, with new logs.

@qubalaz I can report a new bug but running `ubuntu-bug ubuntu-release-upgrader-core` as directed by the error message I'm seeing when I try to upgrade from 18.04 to 20.04 is bringing me to this page. So I think that's why folks are reporting the bug here.

Yes exactly, bug reporting led me here too.
