@TurkTownBlue OK, so key in exit; to leave the database interface.

Let me look deeper into that error message.

No worries. I’m here for another hour or so!

@TurkTownBlue This is an interesting one, because the error is saying that the disk where the database is stored is read only. This should not be.

We need to look at some logs. Look at the MariaDB logs in /var/logs to see if there is any clues to what is wrong.

Also you can key in this command to see if there is any useful error messages. sudo systemctl status mariadb If unbuntu changed the name you may need to key this instead (remember case is important) sudo systemctl status MariaDB

If all else gives us nothing, you can go back into mysql client.

mysql -u root -p;

create database fog2;
Query OK, 1 row affected (0.03 sec)

drop database fog2;
Query OK, 0 rows affected (0.11 sec)

If those commands complete as expected then the update schema code “should” work.

No MariaDB logs, just a mysql in /var/log

Nothing in that since Friday.

Incidentally, I tried to ‘touch’ a couple of test files in /home/<myuser> and in /tmp, /var etc. Each time I get a "cannot touch ‘test’: Read-only file system.

So it looks like my machine has decided to lock everything down. I don’t understand how it managed to download the FOG package in that case.

[george1421]

@TurkTownBlue Well you might need to do a sudo touch since even if you are an admin, you need sudo to do things to protected directories.

Go ahead and run the mysql commands to create and drop the database. I did find something that we can test if the create fails.

@TurkTownBlue There is something terribly wrong with this installation.

Please run mount and post the full output here.

read only database directories and ubuntu

@TurkTownBlue

Sudo makes no difference.

The mysql command won’t create : Read-only file system.

Bear with. I am logged onto the forum on a different machine. Firefox doesn’t render on the FOG device so I may be a while downloading an alternate Browser.

[george1421]

@TurkTownBlue ok this will be the first time seeing this my self.

edit the following file /usr/lib/systemd/system/mariadb.service or /etc/systemd/system/mariadb.service you may need to launch the text editor as an administrator.

Search for a seciton that looks like thks:

ProtectSystem=full
ProtectHome=true

Change them to this:

ProtectSystem=
ProtectHome=

Then back to the linux command prompt and key in:

sudo systemctl daemon-reload
sudo systemctl start mariadb

@george1421

OK everyone. Now it refuses to download alternative browsers. Looks like my install is seriously flaky.

I’m going to reboot and attempt to re-install FOG.

[george1421]

@TurkTownBlue Sounds like a good next step.

@george1421
It was worse than i thought.

Ubuntu wouldn’t start so it looks like a complete refresh
