LDAP breaks after upgrading to stream - centos

so I just started upgrading all of our centos 8 servers to centos stream and the first one seemed to go pretty smoothly with just these commands:
dnf install centos-release-stream
dnf swap centos-{linux,stream}-repos
dnf distro-sync
but then when I tried to log in with my AD creds it wouldn't let me in. I already tried rejoining the domain and making sure my creds are still good. The only error is in the messages log which says:
Credentials cache I/O operation failed I found something that says it's because the cache files don't exist in /tmp so I copied them over from one of my other servers but still no luck. No other errors or anything useful in other log files just incorrect password logs in secure. I was just wondering if anyone else has run into this issue.

systemctl stop sssd-kcm
rm /var/lib/sss/secrets/*
systemctl start sssd-kcm

Cannot complete pgadmin4 setup. Apache web server

I've got problem with completing pgadmin4 installation thru sudo /usr/pgadmin4/bin/setup-web.sh command.
During this process instalator does not recognizing that Apache is running and asks me if I want to start it:
The Apache web server is not running. We can enable and start the web server for you to finish pgAdmin 4 installation. Continue (y/n)? y
Then it just spits some errors:
Too few arguments.
Error enabling . Please check the systemd logs
Too few arguments.
Error starting . Please check the systemd logs
So far I havn't found where the logs are stored.
About my apache, I am quite sure that my server is running, because I can connect to it through browser, phpmyadmin is working properly, and service apache2 status returns * apache2 is running. By my understanding apache2 is just fancy word for httpd service, and there is no other service called simply apache.
PostgreSQL seems to work properly from command line, haven't tested if I can connect to it yet, but this shouldn't be the case right?
I am using
**PostgreSQL:** 12.5 (Ubuntu 12.5-0ubuntu0.20.04.1)
**Ubuntu:** Ubuntu 20.04 LTS
**Server:** Apache/2.4.41 (Ubuntu)
I had the same issue for Debian 10 and Ubuntu 20. The /usr/pgadmin4/bin/setup-web.sh script is using 'uname -a' which doesn't contain "Debian" identifier in the return string. Updating this to read /proc/version will allow APACHE to be specified as the Debian variant of apache2.
Change:
UNAME=$(uname -a)
To:
UNAME=$(cat /proc/version)
I had a similar problem with Ubuntu running inside WSL 2. Managed to resolve it by modifying the /usr/pgadmin4/bin/setup-web.sh script. I moved these lines outside of the conditional:
IS_DEBIAN=1
APACHE=apache2
This allowed the installation to progress beyond the Too few arguments. error. There was still an error however:
System has not been booted with systemd as init system (PID 1). Can't operate.
Error restarting apache2. Please check the systemd logs
I resolved this by running:
sudo service apache2 restart
After this I tried bringing up the admin page by visiting http://127.0.0.1/pgadmin4 from the Windows host. This still didn't work, and had to connect using the Ubuntu machine's ip address (you can find it out via ifconfig) which finally allowed me to see the login page.

fail2ban and owncloud.log file

I am using the following configuration, ubuntu 16.04 apache2 php 7.0 owncloud 10.0.3. I think I have made an error when I setup ownclound. The data directory lives in /var/www/owncloud/data ( I believe that owncloud.log resides in this folder). I have deployed fail2ban and the issue that I am having is that fail2ban cannot access the data folder because I ran sudo chown -R www-data:www-data /var/www/owncloud/. The only way I access the log file is through the OWNcloud gui settings > general > log. where I can see the failed login attempts by me. I cannot seem to get Fail2ban to read the owncloud log.
I am new to ubuntu and Owncloud can anyone advise how to rectify this issue, owncloud is working fine and I am using ip addresses to restrict access to owncloud. Fail2ban was supposed to make the server secure so that I could open up owncloud to the internet.
Regards
Steve
You should change the permissions of the log file so that it can be read by everyone but written only by the php process. Do a 'chmod 755 /var/log/owncloud/owncloud.log'
By the way. I suggest that you migrate from Owncloud to Nextcloud. It is a full replacement, fully open source, more features and more secure. And it has a fail2ban equivalent brute force protection already build in :-)

Postgres cant connect to server: No such file or directory

I'm running Debian server and use SSH to manage it. Today I tried to install Postgres and follow this steps to do it:
apt-get install postgresql
su - postgres
psql
After the last command I got:
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?
I found several solutions in the Web, but all of them doesn't works for me. As example I found, that I need to delete "postmaster.pid" in here:
/usr/local/var/postgres/postmaster.pid
But I have no such directory as "postgres" in my "var" folder...
Please, help...:(
What you did is correct and normally sufficient except when something goes wrong with the automatic creation of the first cluster by apt-get install postgresql. Often there is an error message like this in the middle of the success reports:
Error: could not create default cluster
Since you can't have done any work with postgres yet, purge the packages with
apt-get purge 'postgresql*'
then reinstall with
apt-get install postgresql
but this time, pay close attention to any error message that would imply that the initial cluster was not created, that will give the actual reason of the problem.

Stuck in starting meteor

This is really frustrating me. I have a DO VPS with ubuntu 14.04 (64) installed.
I installed VestaCP as control panel on that and have hosted some PHP based personal project.
I also installed meteor on it but never used, now when I am trying to create a project and run it ('meteor create rt' then 'cd rt' then 'meteor')
It is giving the following error :
[[[[[ /home/admin/code/rt ]]]]]
=> Started proxy.
Unexpected mongo exit code 1. Restarting.
Unexpected mongo exit code 1. Restarting.
Unexpected mongo exit code 1. Restarting.
Can't start Mongo server.
root#RD:/home/admin/code/rt#
Could anyone please help? Please ask me for more informations if required.
**** EDIT ****
I created a fresh DigitalOcean server and it is giving the same error on that. Some issue with Digital Ocean? File System of Digital Ocean? I am confused. I am trying it on different flavours of Linux and same result. All are fresh linux installations.
I finally got the solution. Posting it here for others.
This was the problem as a few environment variables which mongodb looks for while starting was not set
Set the variables LC_ALL and LANG and it works fine (mostly setting LC_ALL will do)
first, type locale command and see the output, you will see that it will say something about LC_ALL not set.
Now, add these two lines in /etc/environment and it worked.
LC_ALL=en_US.UTF-8
LANG=en_US.UTF-8
This solution is for Ubuntu 12.04 +
Other variants may require similar work.
Unexpected mongo exit code 1 is still an uncaught exception as far as i think.
You can try by updating your c/c++ compilers uptodate. Have a look here.
It says :
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.6
sudo apt-get install g++-4.6
All the best!
So we have narrowed the issue down to meteor's mongo installation on your box (though I think we were pretty sure of this all along). Let's attempt to debug that a bit. The way I have done this in the past is to try to open meteor's mongo with the mongod provided by meteor. You will perform these procedures without running the meteor server. This should give you the warning that is causing Mongo to exit. First you need to find this. In my instance installed on Mint (which should be similar to Ubuntu) it is at:
~/.meteor/packages/meteor-tool/.1.1.3.4sddkj++os.linux.x86_64+web.browser+web.cordova/mt-os.linux.x86_64/dev_bundle/mongodb/bin/mongod
You can look at that location on your Ubuntu box or you can run something like this to get the location:
find ~/.meteor/ -name mongod
Once you find the location then go to the directory of your meteor project you are attempting to run and in that directory you should find this location:
<your meteor project>/.meteor/local
cd into that directory and run the following command:
~/.meteor/packages/meteor-tool/.1.1.3.4sddkj++os.linux.x86_64+web.browser+web.cordova/mt-os.linux.x86_64/dev_bundle/mongodb/bin/mongod --dbpath ./
From there you can analyze the output (or update the question so we can see the output) and this should show you the mongo error you are receiving on startup and allow you to fix it.
I've got the same issues trying to start a meteor app and exactly the mongodb server is being terminated in an unexpectly manner. Generally the virtual linux server from some dealers like the one you mentioned are coming without a swap partition (check in /etc/fstab file) so if you have not enough memory to allocate MongoDB server then meteor app can't be started. You can create a swap partition or instal swapspace
sudo apt-get install swapspace
After that I was able to start the meteor app... Just be patient as swap memory is not as faster as RAM.
Since due some "smart" StackExchange policy I cannot up-vote or comment to working solution...)
Quoted answer works also on Digital Ocean on CentOS 7 x64 vmlinuz-3.10.0-123.8.1.el7.x86_64
first, type locale command and see the output, you will see that it will say something about LC_ALL not set.
Now, add these two lines in /etc/environment and it worked.
I changed the locale setting to match my needs.
Fixed on my Debian 8 with the following bash command, (use sudo if needed)
localedef -i en_US -f UTF-8 en_US.UTF-8

Fabric and init

I am using fabric to restart tomcat and even though it says tomcat restarted successfully it does not. So, as per the FAQ, I set pty=False and tried again. But, now, I get this error:
sudo: /etc/init.d/tomcat restart
out: sudo: sorry, you must have a tty to run sudo
Any ideas around this problem?
To anyone reading this, this is not a problem with fabric but with the way sudo accounts have been set up. This property in /etc/sudoers file controls this;
