Yes, I actually reported the problem only after doing a fresh install on another card first. So vanilla Armbian_5.30_Orangepipc_Ubuntu_xenial_default_3.4.113_desktop.img with single updated package as stated above.
Sure thing. What logs do you need, specifically? Nothing in syslog or systemd journal though. I'm not aware of any logging done by chromium, but I'm sure you can point me in the right direction there.
For the actual error message, see above. Card is a 16GB Sandisk Ultra UHC-I card I took from another SBC. PSU is the old Xunlong 3A one.
How so? Apt-get tells me
