I upgraded SCM-Manager to version 3.4.1 on Rocky Linux 8, scm-server running: ```auto ● scm-server.service - SCM-Manager Server Loaded: loaded (/etc/systemd/system/scm-server.service; enabled; vendor preset: disabled) Active: active (running) since Tue 2024-09-24 08:10:52 CEST; 9s ago Main PID: 83689 (java) Tasks: 29 (limit: 23213) Memory: 393.1M CGroup: /system.slice/scm-server.service └─83689 /usr/bin/java -Djava.awt.headless=true -classpath :/opt/scm-server/conf:/opt/scm-server/lib/* -Dapp.name=scm-server -Dapp.pid=83689 -Dapp.repo=/opt/scm-server/lib> zář 24 08:11:01 linux64.hcv.cz scm-server[83689]: 08:11:01.945 [main] DEBUG org.apache.commons.beanutils.converters.ArrayConverter - Converting 'java.net.URL[]' value '[Ljava.net.UR> zář 24 08:11:01 linux64.hcv.cz scm-server[83689]: 08:11:01.945 [main] DEBUG org.apache.commons.beanutils.converters.ArrayConverter - No conversion required, value is already a j> zář 24 08:11:01 linux64.hcv.cz scm-server[83689]: 08:11:01.989 [main] INFO sonia.scm.lifecycle.modules.ScmSecurityModule - bind security realm class sonia.scm.legacy.LegacyRealm zář 24 08:11:01 linux64.hcv.cz scm-server[83689]: 08:11:01.989 [main] INFO sonia.scm.lifecycle.modules.ScmSecurityModule - bind security realm class com.cloudogu.scm.ssh.auth.Public> zář 24 08:11:01 linux64.hcv.cz scm-server[83689]: 08:11:01.990 [main] INFO sonia.scm.lifecycle.modules.ScmSecurityModule - bind security realm class sonia.scm.initialization.Initial> zář 24 08:11:01 linux64.hcv.cz scm-server[83689]: 08:11:01.990 [main] INFO sonia.scm.lifecycle.modules.ScmSecurityModule - bind security realm class sonia.scm.security.DefaultRealm zář 24 08:11:01 linux64.hcv.cz scm-server[83689]: 08:11:01.990 [main] INFO sonia.scm.lifecycle.modules.ScmSecurityModule - bind security realm class sonia.scm.web.security.Administr> zář 24 08:11:01 linux64.hcv.cz scm-server[83689]: 08:11:01.990 [main] INFO sonia.scm.lifecycle.modules.ScmSecurityModule - bind security realm class sonia.scm.security.ApiKeyRealm zář 24 08:11:01 linux64.hcv.cz scm-server[83689]: 08:11:01.990 [main] INFO sonia.scm.lifecycle.modules.ScmSecurityModule - bind security realm class sonia.scm.security.AnonymousRealm zář 24 08:11:01 linux64.hcv.cz scm-server[83689]: 08:11:01.990 [main] INFO sonia.scm.lifecycle.modules.ScmSecurityModule - bind security realm class sonia.scm.security.BearerRealm ``` But cannot access web GUI: ```auto HTTP ERROR 503 Service Unavailable URI: /scm/repos/ STATUS: 503 MESSAGE: Service Unavailable SERVLET: - ``` How can identify path to change in config.yml: contextPath,tempDir: webapp: workDir: homeDir: from previous version?

Hi @egroups , I’m not sure if I get your problem right. The relevant path should be the `homeDir`. This is the path to the data file of SCM-Manager (you should find directories like `repositories` and `config` here). Looking at your 503 error it looks like you are using a reverse proxy. Have you set the correct port in the `config.yml`? ---

I setup homeDir and now I can login to web UI,but First Initialization.How can add previous repositories? ---

With “first initilization” you mean the step where you have to enter the token and create the first admin user? If you see this, you have not set up your `homeDir` correctly in the `config.yml` or it is not readable by the SCM server. The part of the file has to look something like this: ![image](https://europe1.discourse-cdn.com/flex013/uploads/cloudogu2/original/2X/2/24ae94c92df7fef1fa9ef05909d6d63eeb2dc8f5.png) If you have set a path for `homeDir`, what do you get if you run a `ls `? ---

I create temporary Docker SCM-Manager 2.48.3,move dir repositories from old scm-server to /var/lib/scm/,chown -R scm:scm repositories,modify /var/lib/scm/config/repository-paths.xml. After that I export all repositories (dump). Returned to old server and import this dumps,it’s OK. I created snapshot VM. This is my config.yml: ```auto webapp: workDir: homeDir: /opt/scm-server/work/webapp ``` ll homeDir ```auto drwxr-xr-x 2 scm scm 4096 26. zář 09.36 config drwxr-xr-x 5 scm scm 66 24. zář 15.45 index drwxr-xr-x 3 scm scm 20 24. zář 13.48 lib drwxr-xr-x 6 scm scm 96 24. zář 13.48 plugins drwxr-xr-x 4 scm scm 42 24. zář 17.02 repositories drwxr-xr-x 4 scm scm 30 24. zář 15.45 var drwxr-xr-x 7 scm scm 142 24. zář 13.48 webapp ``` SCM GUI working. After restart all is missing and again ‘Finish Initialization’. Why? ---

I changed in config.yml tempDir: to /var/cache/scm/work/webapp and remove diacritic from repositories descriptions. Now working OK ---

I’m glad that you got it running, @egroups . So you think the diacritics have been the problem? That’s not how it should be and we will check here. After your first reply I thought about whether your path mapping in docker and the user mapping is okay… Thanks for the update!
