[Bug 1960727] Re: When apt holds back updates, it fails to inform the user of the reason

2022-02-13 Thread David Hillman
For over a decade now, at least, users have continually been puzzled by
this silent refusal.  Again, in most contexts, that indicates a failure
of the interface.

[Bug 1960727] Re: When apt holds back updates, it fails to inform the user of the reason

2022-02-13 Thread David Hillman
Nearly anything would be better than the current state of silent
failure.  At present, probably many thousands of Ubuntu systems are
reporting the following:

root@system:/home# apt-get upgrade
Reading package lists... Done
Building dependency tree   
Reading state information... Done
Calculating upgrade... Done
The following packages have been kept back:
  libnvidia-cfg1-470 libnvidia-compute-470 libnvidia-compute-470:i386 
libnvidia-decode-470 libnvidia-decode-470:i386 libnvidia-encode-470

Providing not even a hint as to which of those packages is uninstallable, or 
why, would be unacceptable in most development contexts.  In this case, with 
preceding versions of most or all of those packages already installed, it is 
far from clear to end-users why their system refuses to install official 
upgrades.

Not many software tools respond to user instructions with a simple "No",
and that's generally considered bad practice.

[Bug 1960727] [NEW] When apt holds back updates, it fails to inform the user of the reason

2022-02-12 Thread David Hillman
Public bug reported:

In the case where apt refuses to install and holds back certain
packages, only the following output is produced:

root@system:/home/admin# apt upgrade
Reading package lists... Done
Building dependency tree   
Reading state information... Done
Calculating upgrade... Done
The following packages have been kept back:
  [ List of packages ]
0 upgraded, 0 newly installed, 0 to remove and 24 not upgraded.


Missing is any explanation about which package is responsible for apt refusing 
to perform its job, or even what is the reason for that package being 
uninstallable.

This bug leads users to believe that official Ubuntu packages are
routinely misconstructed, corrupt, or otherwise junk.

Fix: Instead of apt simply responding "No Dave, I'm Afraid I Can't Do
that", correct the output to include the specific package that has a
missing or unresolved dependency, so the user a) has confidence that the
process works correctly and b) can proceed with fixing the problem.


This bug is longstanding, so I don't think version details are required, but 
they follow anyway:

1) Distributor ID: Ubuntu
Description:Ubuntu 20.04.3 LTS
Release:20.04
Codename:   focal

2) # apt --version
apt 2.0.6 (amd64)

** Affects: aptitude (Ubuntu)

[Bug 1926823] [NEW] Samba 2:4.11.6+dfsg-0ubuntu1.8 Hangs for 20 to 30 Seconds

2021-05-01 Thread David Hillman
Public bug reported:

I installed the latest version ( Samba 2:4.11.6+dfsg-0ubuntu1.8 ) of the
samba package to two Kubuntu 20.04.2 LTS servers yesterday.  Now all of
the samba clients -- Linux and Windows -- intermittently hang for 20 to
30 seconds every few minutes.  After that time passes, the samba daemons
become responsive again, with no human intervention.

Samba has been running on these servers for a few years, with no such
previous instances, and nothing else changed yesterday.

log.smbd is clean, and reports no errors or other information.

[Bug 103439] Re: Photo import stopped working with Canon PowerShot A520

2007-06-11 Thread David Hillman
I have a Canon Powershot SD550 that was working beautifully with Edgy
Eft.  I upgraded to Feisty Fawn yesterday, and now the camera is not
recognized at all.  I applied the patch above, but that failed.

Had I known how many things were going to need to be redone after
installing FF, I never would've bothered.
