Is spacewalk-setup-postgresql needed?
by Stefan Bluhm 25 Jul '21

25 Jul '21

Hello, It seems that the package spacewalk-setup-postgresql is not used during the Uyuni setup phase. It is not installed on Enterprise Linux and not even available on LEAP 15.3. In April, changes were still done to that package. Can this package be removed then? Best wishes, Stefan

Moving config from susemanager.spec
by Stefan Bluhm 20 Jul '21

20 Jul '21

Hello, whilst cleaning up some more error messages, I came across this section in the susemanager.spec https://github.com/uyuni-project/uyuni/blob/master/susemanager/susemanager.… %posttrans # make sure our database will use correct encoding . /etc/sysconfig/postgresql if [ -z $POSTGRES_LANG ]; then grep "^POSTGRES_LANG" /etc/sysconfig/postgresql > /dev/null 2>&1 if [ $? = 0 ]; then sed -i -e "s/^POSTGRES_LANG.*$/POSTGRES_LANG=\"en_US.UTF-8\"/" /etc/sysconfig/postgresql else echo "POSTGRES_LANG=\"en_US.UTF-8\"" >> /etc/sysconfig/postgresql fi fi Can I move this to "/susemanager/bin/mgr-setup" or is it to clean some legacy installations? Best wishes, Stefan

Difference in py26-compat packages
by Stefan Bluhm 12 Jul '21

12 Jul '21

Hello, can anyone tell me the difference between these two packages: python2-tornado and py26-compat-tornado python2-msgpack and py26-compat-msgpack-python I noticed that py26-compat-salt requires the python2-XXX packages for build but requires py26-compat-XXX packages for runtime. This would require to maintain two packages for each of these cases. Best wishes, Stefan

Bootstrapping with web UI is performed with salt-ssh (even if you are bootstraping ordinary minion, not ssh one) through salt-api service. To find out exact error it's better to set logging level for salt master to trace: /etc/salt/master.d/logging.conf: log_level_logfile: trace Could be done with any conf file under /etc/salt/master.d/ no need to restart salt-master, but salt-api only. Unfortunately most of the messages required to debugging are visible it trace logging level only, but it's too noisy and log file is growing to fast.

The py26 packages were not installed so I guess this is a missing dependency that needs fixing. I installed them, now the salt api log is empty and I am back to square 1: No log entries at all. a) What OS is installed at the client? Since py26 is mentioned, I guess CentOS6? AlmaLinux 8 b) How are you bootstrapping? WebUI? Script? WebUI (Systems --> Bootstrapping) c) What kind of client do you intend to bootstrap? SSH or regular salt minion? I actually don't know. I guess SSH as it mentions SSH on the page? Maybe here is the user error. I don't know anything about boot strapping. This is what I did: 1. Installed Uyuni. 2. Loaded the channels and created an activation key 3. Kickstarted an Alma Client. Now I am trying add the Alma Server to the Uyuni system management. I did nothing further on the client assuming the WebUI boot strapping is doing everything.

When entering "host" (tried IP/hostname), "user"/"password", "activation key" and "Disable SSH.." under "Systems --> Bootstrapping" a blue info message appears "Your system is bootstrapping: waiting for a response..". After some long time, the bar changes to the red error bar saying: "Server error, please check log files.". Where are the logs for the bootstrap attempts? I claim, I searched "everywhere". In this case, this seems to be problem at the server, not at the client. /var/log/rhn at the server is the place where you need to start looking. Most likely there will be an ISE (Internal Server error) there. In some cases it could be interesting having a look at the tomcat log and PostgreSQL logs.

Merging custom CentOS packages to Master
by Stefan Bluhm 07 Jul '21

07 Jul '21

Hello all, Next big activity is pushing the required CentOS 8 packages to the Uyuni Master branches. The distribution of packages to repositories on the Uyuni Server are: - Uyuni Master: 98 + Uyuni Master Other: 58 - New custom packages: 46 - EPEL: 34 - PowerTools: 50 - CentOS 8 BaseOS: 477 + CentOS 8 AppStream: 196 1) I would push my newly created custom packages including kits to "Uyuni Master Other". Are there any guidelines? Otherwise I would just split out the change log of the spec file and submit. 2) What do we do about the EPEL and PowerTools packages? I feel a bit uneasy of pushing 84 packages (+ probable build dependencies) to OPS. Especially when you consider that these packages need to be maintained and monitored for security fixes. 3) One more (not so pleasant) thought is the module system. Installation requires activation of 10 modules and deactivation of 2 more modules. If we go for loading all packages of point 2) into OBS, we might as well add the ones from the modules and create an Uyuni Server module (one per major release?). That would simplify the user experience and probably use the module system as intended (but kill maintainability...). Let me know your thoughts and ways to continue. Best wishes, Stefan
