I'm running Kali 2020.3 (64 bit) live on 16GB pendrive.
On the beginning, dealing with E: You don't have enough free space in /var/cache/apt/archives/ wasn't that hard to me. Apt-get clean was fixing everything. But now, every time I want to upgrade, the same error appears.

kali@kali:~$ sudo du -ch /var/cache/apt/archives
4.0K /var/cache/apt/archives/partial
8.0K /var/cache/apt/archives
8.0K total

I've seen many posts and solutions - even re-routing location does nothing. Cleaning journal logs has the same result.
Thanks in advance for tips.
