<div dir="ltr"><div>Folks:</div><div><br></div><div>Posting this over here, been having issues with 20.10 functionality since moving Lu & U-MATE up . . . overall I have to say both are "slow" . . . slow to boot, slow to reboot, stuff just happens "slowly" . . . not quite as bad in Lubuntu, but overall the impression to this end-user is "meh" . . . . I've filed a number of bug reports, todays involved both Lu & U-MATE and errors involving grub updating packages that wipe out the other distros on grub's list. This problem has been happening for quite a while . . . devs don't seem to be able to understand the problem???? But, it's just about a "deal breaker" as far as using ubuntu . . . .</div><div><br></div><div><a href="https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1894242">https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1894242</a></div><div><br></div><div><p>"Today both of my ubuntu 20.10 installs had "grub" packages to upgrade, Lubuntu & U-MATE . . . over the last year?? upgrading grub in ubuntu has managed to wipe the grub listings of the other systems I have installed, leaving only U-MATE to boot up. I've had to use SG2 disk to boot into OpenSUSE to repair the damages done by the ubuntu grub process . . . it keeps happening.</p> <p>Today I ran the Lu apt dist-upgrade and it had a few grub packages to upgrade . . . I ran them . . . I rebooted and, yep, grub list was again wiped . . . and into U-MATE we went. I ran apt over here and it showed the same grub packages . . . since the damage was already done I ran it. This time it actually showed errors with "grub-install" . . . . I may have other bug reports on this problem, but it seems like ubuntu's grub doesn't get "EFI"??? Devs haven't gotten this issue addressed as of this date??
