I am trying to install openstack Wallaby on Ubuntu 20.04. I already installed Keystone and Glance and they work as expected. But after I installed Placement and tried to verify it using 'placement-status upgrade check' I constantly get the same error.
Error:
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/oslo_upgradecheck/upgradecheck.py", line 196, in run
return conf.command.action_fn()

File "/usr/lib/python3/dist-packages/oslo_config/cfg.py", line 2543, in find_file
raise NotInitializedError()
oslo_config.cfg.NotInitializedError: call expression on parser has not been invoked
Is this normal at this stage or am I doing something wrong here?
I already checked the database connections (user and password work and database is made). And I also checked the username, password and url options in keystone_authtoken in placement.conf but I can't find what's wrong.
I also encountered this problem with Wallaby on Ubuntu 20.04. I solved it with installing Placement from PyPI instead of Ubuntu package manager so far. You should consider how implement starting Placement automatically if you install Placement from this instruction.
Install and configure Placement from PyPI
https://docs.openstack.org/placement/wallaby/install/from-pypi.html
I had the same problem so changed to Victoria, same issue. Digging about in the docs though I found the issue. The command that populate the database looks similar for Keystone, Glance and Placement but for placement the command should be 'su -s /bin/sh -c "placement-manage db sync" placement'. Notice that for placement it is 'db sync' not 'db_sync' as it is for the others. I created scripts, well actuall am using ansible and just cut and pasted between them and my guess is you have done the same. Basically as it does not run the database is empty hence the error.

I'm trying to use microk8s for my KubernetesPodOperator in my dag. Unfortunately I can't seem get it to install consistently.
I'm using homebrew to install (or reinstall) microk8s and multipass. When I execute
microk8s install --cpu=4 --mem=10000
I get the errors:
launch failed: The following errors occurred:
qemu-system-aarch64: Error: HV_BAD_ARGUMENT
launch failed: instance "microk8s-vm" already exists
An error occurred with the instance when trying to launch with 'multipass': returned exit code 2.
Ensure that 'multipass' is setup correctly and try again.
(where launch failed: instance "microk8s-vm" already exists appears several times.)
I've tried reinstalling both several times and that doesn't appear to help. Any advice?
Turns out I need to be using microk8s install --cpu=4 --mem=10 not 10000. It wants GB, not MB. My bad. I wish the error message was a little clearer though.
Today's (1 Mar 2016) OpenSSL release has caused the following error when running Plone/Zope
.buildout/eggs/ZODB3-3.10.5-py2.7-linux-x86_64.egg/persistent/cPersistence.so: undefined symbol: SSLv2_method
It's hard to see what's going on since it's a binary file. I also tried updating to ZODB3 3.11.0 which yields the following traceback
.buildout/eggs/ZConfig-2.9.0-py2.7.egg/ZConfig/loader.py", line 217, in schemaComponentSource
package=package)
ZConfig.SchemaResourceError: could not load package ZServer:
.buildout/eggs/zope.security-3.7.4-py2.7-linux-x86_64.egg/zope/security/_proxy.so: undefined symbol: SSLv2_method
Package name: 'ZServer'
File name: 'component.xml'
Package path: None
Is there any workaround for this other than reverting OpenSSL?
zope security is a compiled egg, like all the ones ending with -py2.7-linux-x86_64.egg.
As the traceback says, it cannot find anymore a symbol.
Probably you have to recompile it with the new openssl-dev.
I would try (on a development server first):
backup your compiled egg (mkdir eggs-backup && mv `eggs/zope.security-3.7.4-py2.7-linux-x86_64.egg eggs-backup/)
rerun buildout
This will recompile your missing egg.
Hopefully it works and hopefully it is the only one linked to that library.
Anyway, dependending on the way you patched openssl you may have a lot of other issues (I am thinking about Python, urllib*, curl, wget, ...)
OpenSSL 1.0.2g by default doesn't build with SSLv2 (because of the recent DROWN attack). You may need to manually build it without OPENSSL_NO_SSL2 flag.
(but in fact you shouldn't do this if you're doing some server-related stuff, there is a serious security reason because of which it was disabled, see https://drownattack.com)
I was able to resolve this by upgrading python to 2.7.10+, and then upgrading Pillow and lxml.
I am following these instructions(https://www.digitalocean.com/community/tutorials/how-to-install-and-use-graphite-on-an-ubuntu-14-04-server)
to install statsd and graphite, but am running into below stated problem. Seems like this is not a graphite issue but python issue. Does anybody know how to resolve this?
~/build > sudo service carbon-cache start

I was following the same instructions and encountered the same problem.
Moving or removing the /usr/local/lib/python2.7/dist-packages/twisted directory also resolved the issue for me.
You can use for example the following command to change the name of the problematic directory:
mv /usr/local/lib/python2.7/dist-packages/twisted /usr/local/lib/python2.7/dist-packages/twisted2
Then use sudo service carbon-cache start again
Background
I had the same issue on my Ubuntu 14.04 machine. Some investigation indicates that there are two virtually identical areas for twisted plugins on my machine.
/usr/local/lib/python2.7/dist-packages/twisted
and
/usr/lib/python2.7/dist-packages/twisted
I am not sure where these two areas originate from. Perhaps one comes with the distro and the other is created through a manual pip install twisted that I may have done at one time. I suspect that the /usr/local/lib/python2.7/dist-packages/ area gets populated with content when I install packages using pip. So this problem my eventually be attributed to users (e.g. me) installing twisted via pip and via the apt package system.
In any case, a diff through these areas showed that the carbon related files were installed into the /usr/lib/python2.7/dist-packages/ area. dpkg -L graphite-carbon also indicates that the package files go into the /usr/lib/python2.7/dist-packages/ area.
However, when the carbon start script is run is appears that /usr/local/lib/python2.7/dist-packages/twisted/plugins area is used leading to the plugin not being found.
I assume that this issue is related to the modules search path. As can be seen below the /usr/local/lib/python2.7/dist-packages/ comes before the /usr/lib/python2.7/dist-packages/ in my default path.

for some reason twisted was messing up something with graphite.
read on the internet that manually removng twisted solves the problem.
Tried it and it works now
just did
sudo rm -rf /usr/local/lib/python2.7/dist-packages/twiste*
I ran into an odd issue that I cannot fix in any way and I was hoping someone here may have a better understanding of whats wrong;
I am unable to use RWebLogo package - even run the simplest examples due to the same missing Ghostscript error.
e.g. running:
library(RWebLogo)
aln <- c('CCAACCCAA', 'CCAACCCTA', 'AAAGCCTGA', 'TGAACCGGA')
weblogo(seqs=aln, file.out='mylogo.pdf')
Throws this error:
Traceback (most recent call last):

EnvironmentError: Could not find Ghostscript on path. There should be either a gs executable or a gswin32c.exe on your system's path
I have installed ghostscript ver 9.15 with configure/make/install in the terminal and then added the PATH to bash profile and executed it. When I run gs in the terminal it works, confirming it is set to the system path, yet the same error still occurs. Even after rebooting.
I tried adding the gs to the environment in R directly:
Sys.setenv(R_GSCMD = "/Applications/ghostscript-9.15/bin/gs")
which also hasn't helped... Gives exactly the same error. When I search the R environment it shows that gs is there.
Important version information:
MAC: OS Yosemite 10.10.1;
R version 3.1.1 (2014-07-10);
Platform: x86_64-apple-darwin10.8.0 (64-bit);
RWebLogo_1.0.3
Do you know of any issue that may have cause this problem? I'm new to programming, so I am worried I may be missing something basic. I would be grateful for any advice. Thank you!
I have gotten in touch with Omar, the author of RWebLogo, and he has been really helpful in pinpointing my problems and resolving the issue.
First, he advised to run the RWebLogo on a test sequence on the terminal:
/Library/Frameworks/R.framework/Versions/3.1/Resources/library/RWebLogo/extdata/weblogo-3.3/weblogo -f test_seqs.txt -o ~/Desktop/out.pdf -F pdf
Change the base directory (everything before extdata/weblogo …) of the script above to be whatever the command below gives you in R:
system.file(package = 'RWebLogo')
I ran it and got a new error: the lack of numpy. I actually had the numpy installed but without full user privileges. After reinstalling numpy, the RWebLogo was successfully running from the terminal.
Still, the RStudio was throwing a GhostScript error. Omar suggested that there is a problem with an older version of RStudio running on Yosemite (I currently have 10.10.1), and sent me a link to an updated RStudio version where the problem was fixed.
http://www.r-bloggers.com/r-and-rstudio-incompatibility-with-yosemite-mac-os-x-10-10/
I got the updated RStudio and everything works great there right now. Hope this helps someone with a similar issue!
On "./configure" of an open source project I get:
user agent OS = Linux
./configure: line 13957: syntax error near unexpected token 0.9.3'
./configure: line 13957: GOBJECT_INTROSPECTION_CHECK(0.9.3)'
make: *** [config.status] Error 2
Ubuntu 12.04 package "gobject-introspection" and "libgirepository1.0-dev" are present. Removing the GOBJECT_INTROSPECTION_CHECK line allows configure to complete, but the project fails a dependency later.
How can I get past this configure step cleanly? Googling for this issue shows bugs filed against numerous OS projects for this same blocking issue, but the usual answer is "install gobject-introspection".
As the OP discovered on his own he had to install the gobject-introspection package to get the m4 macros that were being used.
The error message has the raw macro in it, as configure scripts are generated from configure.in/configure.ac files via m4/etc the fact that the raw macro is in the output file indicates that the macro did not get translated at generation time.
The gobject-introspection m4 files were apparently installed after autogen.sh (or equivalent) was run to generate the configure script. Re-running the autogen.sh script should regenerate the configure script and run the macro correctly.
