Hi，UmutBayut
1.What is the version of your Ubuntu OS
2.Have you changed environment variables? such as PATH, and could this command show anything in your Ubuntu OS

1. zyk@zyk-pc:~/work/linux-upgrade/Linux_Upgrade_Tool$ /usr/local/bin/upgrade_tool -v
   
2. Program Data in /home/zyk/.config/upgrade_tool
   
3. Upgrade Tool v1.38
   
4. zyk@zyk-pc:~/work/linux-upgrade/Linux_Upgrade_Tool$
   
5. zyk@zyk-pc:~/work/linux-upgrade/Linux_Upgrade_Tool$ echo $PATH
   
6. /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
