I was running 22.04.4 Desktop without problems. This morning, it asked if update to 24.04.1 Desktop and I unfortunately accepted... The update process blocked in the middle leaving the system in a not usable state: no GUI neither network. So, I tried to reinstall from scratch. I flashed 24.04.1 Desktop ISO on a USB stick with Ventoy. I have / /boot /home swap partitions. So, I went to manual partitioning to avoid formatting /home with my data. The install process stopped very soon, the error on the log is: verifying partition flag, expected swap, found none. By the way, the installer is very unstable, setting the laptop in airplane mode improves stability but still doesn't install. I am without a computer now, I only had Ubuntu, can somebody suggest how install a fresh 24.04.1 Desktop saving my /home partition, please?

I solved the problem in two steps.
To avoid the continuous installer crashes, I booted Ubuntu from pen drive with the option "safe graphics" (it may be due to my nVidia card) after the boot I disabled Wireless/Bluetooth enabling airplane mode.
To avoid the crash during file-copy phase, I did not set the old 22.04 swap partition, I left it unused. After the installation completed, I manually formatted it as swap and linked as swap through /etc/fstab file. By the way, the installer created a 8GB /swap.img on the / which I deleted.
