How to fix the issue of not being able to proceed to the next step when manually partitioning in Ubuntu.

If you are unable to proceed to the next step during the installation process on Ubuntu after manually partitioning, it may be due to the following reasons:

1. Improper selection of mount point: When manually partitioning, it is necessary to select appropriate mount points for each partition. For example, the root partition should be chosen as “/”, the SWAP partition should be chosen as “swap”, and so on. Choosing the wrong mount point could result in the installation program being unable to proceed.

Solution: Re-enter the manual partitioning interface and make sure to select the correct mount point for each partition.

1. Partition table error: If there are errors in the partition table, such as overlapping partitions or unallocated space, the installation process will not be able to continue.

Solution: Re-enter the manual partitioning interface, carefully check the partition table, and ensure there are no errors. If there are any errors, they need to be repaired accordingly.

1. Partition format error: The installation process will not be able to continue if the partition is not correctly formatted.

Solution: Re-enter the manual partitioning interface, ensuring that the appropriate file system is selected for each partition and formatting is done.

1. If there is not enough disk space, the installation program will be unable to proceed.

Solution: Check the disk space and make sure that the target disk has enough available space for installation.
