Looks like the /boot directory is what is causing the flag.
Try running
sudo apt clean && sudo apt autoremove
Check if you had several old kernels:
ls -l /boot
Identify the Old kernels you do not need anymore and remove with apt. Replace old-kernel in the following command with the actual kernel version. For example, if you are removing the 5.15.0-83 kernel:
OK I deleted brave browser in the terminal and did the upgrade but the items we want to remove are still there ..... did a check on Synaptic and Brave and it's Keyring are gone ..... also ran Ubuntu Cleaner again and it found more stuff to remove which it did .....
By the way I tried the normal as well as the minimal install and they both said the same thing with the same amount of disk space required ..... if that helps ....
Sorry it took so long I didn't know what I was doing and it took me for ever to figure it out ..... seems Hidden Files was not selected in Nemo and I found out just by accident as I always have that selected .....
Is there away to move some MB's to my /Boot partition from my swap partition as I'm running 16 GB of RAM so I probably safe with removing some from there ..... I could remove all 2 something GB but that is kinda a lot for a /Boot partition .....
This would be like a last ditch effort unless we can find addition stuff in my /Boot partition to remove .....
Yup ..... that sounds like a plan ..... I can take some from my swap partition add it to my boot and then take some from my / partition and add it back to my swap partition .....
Is there a clear detailed instructions on how to move partitions ????? .....
Can you just slide the partition bar back and forth to increase or decrease the size of the partition ????? .....
Found a Youtube video on extending partitions using Gparted .... worked just fine as I extended my /boot partition to 600 mb and deleted my swap drive and left it as non alighted .... seemed to work ......
