![]() ![]() First, backup, backup, backup! The upgrade process MAY FAIL, due to internet corrupt, hardware issue, and/or package conflict.Before getting started:īefore start upgrading your OS, you have to do some preparations to avoid failure and speed up upgrading process. ![]() It features Kernel 6.5, GNOME 45, new App Center, and has official support until July, 2024. Ubuntu 23.10, code-name, Mantic Minotaur, was released a week ago. A decades old and still working method for verifying the integrity of files is by comparing their checksums.This is a step by step beginner’s guide shows Ubuntu Desktop users how to upgrade to Ubuntu 23.10 from either Ubuntu 22.04 and Ubuntu 23.04. A checksum or hash of a file is a calculated value using hashing algorithms such as MD5. ![]() If the content of the files change, their hashes also change. ![]() This way we can check whether the integrity of files have been compromised. There are many tools for calculating the hash values using a number of hashing algorithms such as MD5, SHA1, RIPEMD and more. But if you want to create and later check the hashes of a number of files simultaneously then you can use EF Checksum Manager. It is available in both installer and portable format. It has a user interface that looks similar to the File Explorer. We can navigate to any drive or folder through this interface. When we have opened a folder under which we want to calculate the checksums, we can select all the files/folders and then click on the Create Checksum icon in the toolbar. It presents with a new window from where we can choose whether there should be just one file for all the hashes or a separate file for all the file hashes. We can also choose to recurse the sub-folders. It uses MD5 as the hash algorithm by default but we can choose CRC32, SHA1, SHA224, SHA256, SHA384, SHA512, SHA-3 224, SHA-3 256, SHA-3 384, SHA-3 512 etc. Once you have created the checksum files, you can verify the integrity of these files by launching EF Checksum Manager, navigating to that folder and clicking on the Verify Checksums icon in the toolbar. The results of the verification will be shown in a smaller window. ![]()
