Unable to enter the management screen when selecting a language for xampp In ubuntu

In ubuntu, xampp cannot access the management screen due to language selection. xampp has a very subtle permission issue. I have never met before. I met today. sort it out. Previously, the xampp installation package was directly downloaded from the official website, and then decompressed to the/opt directory using the tar command, and then run the lamppstart command... in ubuntu, xampp cannot access the management screen due to language selection. xampp has a very subtle permission issue. I have never met before. I met today. sort it out. Previously, the xampp installation package was downloaded directly from the official website, and then decompressed directly to the/opt directory using the tar command. then, the website and mysql services can be started normally with the lampp start command. But today, download the package to the installation package, decompress it to the download directory, and then run the cp-a command to copy it to the/opt directory. At startup, I found that the xampp homepage could be displayed, but I couldn't enter the management screen by clicking the language. Solution: Set the permission of all files except my. cnf to 777 and run the command directly. Sudo chmod 777-R/opt/lampp sudo chmod 755/opt/lampp/etc/my. cnf restart lampp sudo/opt/lampp restart all OK! Solve the problem.
