Ubuntu

automatic reboot after login

Asked by karolus

Last week I tried to install Ubuntu Mate 20.04 daily on Acer Aspire One D270 (Intel Atom N2600 1.6 Ghz CPU, with 2 GB of RAM and 128 GB SSD). The installation was completed but when I restarted the computer, after logging in, the system rebooted automatically, without any intervention on my part. I tried to download a new version of Ubuntu Mate a few days later, I prepared the USB stick with Balena Etcher and I redid the installation from scratch, but the result is always the same. I thought it could possibly depend on some configuration file left in the old home directory (which I had not formatted), so I backed up all the data, formatted the PC and installed it from scratch. Arrived at the login, always the same situation. I had to install Ubuntu Mate 18.04 again because I can't start Ubuntu Mate 20.04 correctly.

If you drop to root recovery and run full updates from there does it work OK?

I'm not able to login as root, I don't know what I have to do. When I
failed installation of Ubuntu Mate 20.04, I reinstalled Ubuntu Mate 18.04,
so at the moment I'm not able to try any experiment on my machine, but I
can try to reinstall 20.04 if it is useful for developpers. Make me know if
I have to do this and what's the procedure to drop to root recovery.
Thank for your interest and for time spent for me.
Carlo

You hold SHIFT at boot and select advanced options. You can select root recovery console and then run:

mount -o remount,rw /

You can now do as you need.

Can you help with this problem?
