You will have to remove the PPA which were added to the system

Step 1: List the PPAs

find /etc/apt/sources.list.d -type f -name "*.list" -print0 | \
    while read -d $'\0' file; do awk -F/ '/deb / && /ppa\.launchpad\.net/ {print "sudo ppa-purge ppa:"$4"/"$5}' "$file"; done

Step 2: Now, remove them

find /etc/apt/sources.list.d -type f -name "*.list" -print0 | \
    while read -d $'\0' file; do awk -F/ '/deb / && /ppa\.launchpad\.net/ {system("sudo ppa-purge ppa:"$4"/"$5)}' "$file"; done

Step 3: Install bleachbit and gtkorphan

sudo apt install bleachbit
sudo apt install gtkorphan

Step 4: Run bleachbit and gtkorphanas root

Step 5: Now, run the command

sudo do-release-upgrade
