Public bug reported:
Binary package hint: brasero
After burning a CD from an ISO file, Brasero reports an error saying
checksum from ISO file and burned CD do not match. ("Some files may be
corrupted on the disc").
However, CD is fine and all files were burned correctly. I did a manual
verification using md5sum on both the ISO and on the burned CD, and they
Steps to reproduce:
- In Nautilus, right-click an .ISO file (i used ubuntu-9.04-desktop-i386.iso) and select "Write to Disc".
- Click "Burn"
After recording, it says "Some files may be corrupted on the disc".
Opening up the logfile, near the end theres the line that triggered the
BraseroChecksumImage Setting new checksum (type = 2)
Steps to Verify:
- Check the ISO hash: md5sum ubuntu-9.04-desktop-i386.iso
( it says 66fa77789c7b8ff63130e5d5a272d67b, same checksum as in Ubuntu documentation https://help.ubuntu.com/community/UbuntuHashes )
- Check the CD hash: md5sum /media/cdrom (again, 66fa77789c7b8ff63130e5d5a272d67b)
- Create ISO from CD using Brasero, and then check md5sum: 66fa77789c7b8ff63130e5d5a272d67b
So Brasero, for some reason, is not calculating the burned CD checksum
I tried with the same ISO twice, and then with another ISO (the one i am
attaching). The 3 discs were OK but in all Brasero reported this error.
PS: This is my 1st bug report, im new to Ubuntu, so I apologize theres
anything incorrect in the report format.
