[Bug 1851170] [NEW] GRUB2 version over 19 all bugs and don't want to start

[PJR Michel]

Public bug reported:

GRUB 2 does not want to start the last version upgraded .32
Only an old version is capable to start with the current version .19 and from a Manuel selection
If I suppress the new package with an online command then the GRUB2 does want to start the old version  19 only there available and the .19 which heritages the last bug and does not start
