My config
1. DigitalOcean droplet Basic / 1 GB / 1 vCPU /25GB
2. CHR 6.49.6 with very simple config, all work fine.
I tried to upgrade to stable 7.4.1 and my vm not booting after that.
In recovery console i got error
"ERROR: could not mount disk!
Please attach it somewhere else."
As far as I understand, this error is generated by the chr bootloader.
So, my question - how to upgrade without reinstall chr?
