I downloadet Ubuntu and copied to my USB pen with Windows 10.

And after reboot, I installed Ubuntu on the same Laptop. After some software installation Ubuntu asked me first to update to version 18.10, I confirmed and updatet. Round 3days later Ubuntu asked me again to update to Version 19.04., I also confirmed.

But now,I dont have any write access to my USB pen.I cant delete the files or I cant format the pen. But copy from the pen to Ubuntu is working without issues.

I read a lot of ways to fix it on the internet, but nothing is working.

When I try to format I get the error:

Error wiping device: Failed to open the device '/dev/sda2' (udsiks-error-quark, 0)

When I try to format with gnome-disks, I cant because formatting is grey and I cant click on it.

When I try to open with gparted I have the same read-only error

Unable to open /dev/sdb read-write (Read-only file system).  /dev/sdb has been opened read-only.

and in the systemlog:

/var/log/syslog

and state of

sudo hdparm -r0 /dev/sdb

/dev/sdb:
 setting readonly to 0 (off)
 readonly      =  0 (off)

What can I do to fix the USB pen?
