(solved) blkid informs that there are two swap partitions

#blkid
/dev/sda3:UUID=fb5a1a10-7a2f-4fa9-b4c9-0d38e87f1c60 type swap
/dev/sdb3:UUID=6271c1d8-f255-45d6-bd64-92dd70ce8193 type swap

The real swap is /dev/sdb3. /dev/sda3, in reality, is a /home (ext4) partition but it cannot be mounted as the system recognizes it as swap. How can I fix it? Thanks

Try another tool, and if that reports /dev/sda3 you probably mistyped /dev/sdb3 and formated /dev/sda3 as swap.

It is also possible that the OP "turned on" the swap option using the "swapon" command and directed that line to sda3, isn't it? Would that command just tell the kernel that sda3 is a swap partition but leave the data on the /home partition intact?

Thanks bstaletic and moonswan:
Maybe that is what is happening MoonSwan. here is the result of #fdisk -l. it seems you are right. According to it, /dev/sda3 is not swap. But in this case, how can I fix it? to change sda3 from swap to ext4 partition as it really is?

so how can I be sure the /home data at /dev/sda2 is instact?

Try:

swapoff /dev/sda3
mount /dev/sda3 /mtn
ls /mnt

If that looks like your home partition, the data is intact. Unfortunately I dought it.

I thank you Bstaletic for your attention. Unfortunately my home partition data has been destroyed. Nevertheless, I think the thread has had a good solution as I have had the opportunity of remembering that the command line is very powerful and that you have to deal with it with much attention and think before you execute any command in order to avoid an unpleasant result as I have described. In the end, I had to reinstall.
