Buster bug report thread

[jamesh]

This thread is for preliminary/anecdotal bug reports on the Buster release.

Once bugs are confirmed, you should use the github repo to make an official report.

For Linux kernel issues: https://github.com/raspberrypi/linux/issues
For Firmware issues: https://github.com/raspberrypi/firmware/issues
For Userland issues (demo apps etc) : https://github.com/raspberrypi/userland/issues
For Raspbian issue: TBD
For Desktop issues: TBD

I will curate this thread, so if I don't think a post is relevant it will be deleted without warning.

Thanks James.... My starter for 10

When running twin headed, it seems that minimizing a window on the second monitor and then expanding it does not remove the "[ ..... ]" around the window name in the task bar (which is on the first monitor).

one change from stretch, iwconfig is not working anymore in rc.local without sudo

Code: Select all

Edit: it is not working with sudo as well, it is working manually from the command line

OK, this is surprising, the OS team adopted the new java 11 in buster as the default java but it is not supported anymore in the old armv6 (pi0).

this is like discontinuing java totally for Pi zero

the topic is been discussed previously in:
https://www.raspberrypi.org/forums/view ... p?t=196887
https://www.raspberrypi.org/forums/view ... 4#p1461934

there is no way out of this except going back to java 8 in buster

also please find the installation error:

VNC needs to have the screen resolution set by raspi-config before the first connection else it errors.

I found myself needing to re-image an SD that I've been using on a Pi Zero-W yesterday and found that Buster was the current available image.
FWIW, I use the "lite" image and after imaging I put my standard wpa_supplicanf.conf file in boot along with and SSH file so I can do a headless setup and only supply power.

I've used this method (and files) countless times and it works perfectly on Pi2, Pi3B+ and Pi Zero-W, however, this now seem to be broken with the current Buster image. Using an old Stretch image and the same file on the same hardware (Pi, SD, powersupply) and everything works fine.
Doing iwconfig confirms connection to the hotspot, but ifconfig occasionally shows an ipv6 address occasionally, but 9 times out of 10, no ip.

In trying to debug I found that dmesg is spammed is endless coppies of:

For the timebeing I've gone back to Stretch, but am happy to try re-imaging another card to try suggestions for a fix on Buster.

Short problem description: Audio truncation on playback

Steps taken to produce:

Downloaded the 2019-06-20 Raspbian Buster Lite zip file.

Verified the sha256 sum.

Unzipped the img file and dd'd it to a 16GB SanDisk Ultra uSD card.

Inserted the card into a 3B with only the following plugged in: HDMI monitor, USB keyboard and speakers in the 3.5mm jack.

Powered up the system and logged in.

Entered the following command:

Code: Select all

aplay /usr/share/sounds/alsa/Front_Center.wav

Listened as the speakers played "Front cen", cutting off the end of "center".

Reproduced the problem with various other wav files in the /usr/share/sounds/alsa directory. Playback on all files was truncated to various degrees.

This problem first cropped up in the 4.19.42-v7+ kernel (2019-05-17) and has been reported by more than one user there. And it seems that it's still there in Buster.

[Ernst]

Anyway, the first install went off well (using my own Logitech K400 keyboard & trackpad) although the updating took a fair time, and I made sure to select the UK keyboard option. However, when it loaded into 'Buster' this had reverted to a US Keyboard (@ sign in the wrong place!) which I had to change to the UK option. I was then offered a choice of Character set (I think that's right) but wasn't sure which one to choose!

I have hijacked the above quote because this might be related to something I noticed while installing Buster.
On initial startup I selected Germany but English language, a bit later while trying to access another Pi using ssh I got some error messages concerning locale. I finally fixed the problem by editing /etc/default/locale to set LANG=en_GB.UTF-8.

The image used was: 2019-06-20-raspbian-buster.img. The initial contents of the file /etc/default/locale was:

Code: Select all

#  File generated by update-locale
LANG=en_GB.UTF-8

I selected country Germany, language German, Time zone Berlin, but selected "English language" and deselected "US keyboard.

P4560347.JPG (185.64 KiB) Viewed 8910 times

Immediately the file /etc/default/locale changed to:
/etc/default/locale:

Code: Select all

#  File generated by update-locale
LANG=en_US.UTF-8
LC_ALL=en_US.UTF-8
LANGUAGE=en_US.UTF-8

With the image 2019-06-20-raspbian-buster-lite.img the contents of /etc/default/locale is as expected:

Code: Select all

#  File generated by update-locale
LANG=en_GB.UTF-8

[Complaint Mode]
For many years I have had discussions at higher levels with Microsoft (and other companies) that country does not imply language and does not imply date format. My residence is in Germany, but I am not a German national, my mother language is not German or English, for historic reasons my preferred language is English but not US english and not South African English, as there is no universal English I normally use UK English, my normal keyboard is German. Why can't I select Country=Germany, Language=UK English, Date Format= UK English, Time Zone=Berlin. And why can I not select the keyboard (German) at this point ?
[/Complaint Mode]

Another test with country Germany, language German, Time zone Berlin, but not "English language" and not "US keyboard. resulted in

Code: Select all

#  File generated by update-locale
LANG=de_DE.UTF-8
LANGUAGE=de_DE.UTF-8
LC_ALL=de_DE.UTF-8

and the keyboard changed to german.

Reminds me of this Alan Parsons song "Damned If I do"

I just flashed Buster Lite on a fresh SD card and put it into my Pi Zero W. It does boot fine, reports to resize the Boot Partition and boots again. The boot process is also working the second time, but it’s the automatically started update process that’s worrying me a bit: it has been running for multiple hours now, with no more information than something along the lines of “Checking and downloading updates” (seems I can issue commands while the setup is still running, and I made the mistake of running dmesg, so I no longer see the original message). It never reported to have completed. This is the second run of going through the setup process, I rebooted the first one impatiently, and the result was a system with garbled keyboard layout names, so I reflashed.

Is the setup process of a fresh install supposed to take that long? Does it report when it’s finished? Is there any way to see what exactly it’s doing behind the scenes (and get a more fine grained progress report)?

I am trying to get this Aeotec Z-Stick Gen5, Z-Wave Plus USB to work on Buster:

https://www.amazon.co.uk/Aeotec-Z-Stick ... th=1&psc=1

I don't see this device appear when i connect it:

/dev/ttyACM0

It talks to the device via a serial connection and i then use it via Home Assistant. Has something changed for USB drivers?

I'm going to cross post this over on the HA forum for awareness.

Is the setup process of a fresh install supposed to take that long? Does it report when it’s finished? Is there any way to see what exactly it’s doing behind the scenes (and get a more fine grained progress report)?

I eventually rebooted after some 4 hours, and the result is again that keyboard layout selection is completely garbled (some layout names are displayed in French, some in Dutch, some as black squares, really strange):





Here are the steps that allow me to reproduce the issue:

1) Download the Buster Lite Image from the official website (The checksum does match for my download)
2) Use Etcher on macOS to flash the image (I let Etcher extract the zip for me)
3) Remove and reinsert the card in the MacBook SD slot to mount the boot partition in macOS
4) Duplicate the LICENSE.broadcom file, then rename the duplicate to “ssh” and delete its contents
5) Eject the card and insert into the Pi Zero W (Pi has Internet connection via USB hub + Ethernet dongle)
6) Power up the Pi
7) The Pi will get stuck at “[OK] Started Daily apt upgrade and clean activities.”
At this point, it is possible to use a USB keyboard (attached to aforementioned hub) to log in and issue commands. This allowed me to verify that the Pi has Internet Access (Ping Google.com) and (after having waited for ~4 hours), to reboot via sudo reboot
8) Steps Continue below screenshot


That’s as far as it boots up. No input was entered to this point.


8) Reboot
9) Log in using default credentials (via the Pi itself, ssh is not actually used)
10) Start raspi-config
11) Choose Localisation Options > Change Keyboard Layout
12) Layout names are partly in French, partly in Spanish (or is it Italian?), partly black squares; It’s impossible to find the correct configuration without proper labels. See image above.

Hi,

It seems that the utility nft is not present in the Buster image.

However if I remove, then reinstall iptables, it is correctly installed. See transcript below (on a fresh image, after sudo apt-get update && sudo apt-get dist-upgrade).

The iptables package recommends nftables, but does not require it. Whether recommended packages are included depends on method and options such as --no-install-recommends.

This is not a bug, unless you are saying that nft is too important to be left out of the image. I do not think it was in the stretch images either.

It's a known issue with Debian. Being worked on.

Could you clarify which of the bugs reported above you're referring to here? If it's the one I posted above, I'm wondering whether it's the "[OK] Started Daily apt upgrade and clean activities" getting stuck, the garbled keyboard language selection or the combination of the two?

Could you clarify which of the bugs reported above you're referring to here? If it's the one I posted above, I'm wondering whether it's the "[OK] Started Daily apt upgrade and clean activities" getting stuck, the garbled keyboard language selection or the combination of the two?

Certainly. I should have made that clear in my original post. It was your one about the keyboard layout being scrambled.

Certainly. I should have made that clear in my original post. It was your one about the keyboard layout being scrambled.

Thanks! I'll use ssh for now then. One last question about the "[OK] Started Daily apt upgrade and clean activities" thing: Did this actually get stuck or is there just no more message following as the boot procedure is finished after that?

The following additional packages will be installed:
libjansson4 libnftables0 nftables

The iptables package recommends nftables, but does not require it. Whether recommended packages are included depends on method and options such as --no-install-recommends.

This is not a bug, unless you are saying that nft is too important to be left out of the image. I do not think it was in the stretch images either.

Thanks for the clarification, did not know as I was completely confused not to find installed by default the tool mentioned in the documentation to configure iptables. I don't say it is important, just that it's a bit confusing. Thanks again.

Chromium is "Aw Snap!" error page too much. example page www.zdnet.com even the forum pages have had the same error.

Have removed the "odblober" whicjh is added for everyone as this was giving error reports saying it had to restart. but still having the problem using the browers on a pi4 1GB ram. (up todate (update/upgrade) done 20 mins ago . 14:40 28/6/19

When booting a twin headed setup, it seems sensitive to both monitors being powered up (i.e. not in stand-by/sleep mode) If HDMI-1's monitor is sleeping then no video is seen on HDMI-0's monitor. I don't know if linux has started or not. Next time it happens I'll try pinging it from another machine.

Hi,

EDIT : it's a DHCPCD5 problem. I had to remove it, and install Wicd instead.

WiFi handling problem with new Raspbian 10 Buster new version of the Network Manager : it cannot handle anymore USB WiFi Dongle TP-Link TL-WN722N (V2) (while was working fine with Raspbian 9 Stretch).

Despite the fact this WiFi dongle is still working fine by manual commands !!



It's based on Realtek rtl8188eu, and it still works fine by manual wpa_supplicant command for connecting to WiFi so it seems to be related to a regression into the Network Manager. However, this regression doesn't appear to cause issue on an Ralink USB WiFi dongle (Tenda W311U : Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter), and no issue with the integrated WiFi module of RPi 3 and +.

It's not about kernel, firmware-realtek, or wpasupplicant :
After rpi-update to 4.19.56-v7+ on both Raspbian 9 and 10, no change. No differences between Raspbian 9 and 10 firmware realtek files : /lib/firmware/rtlwifi/rtl8188* files are the same (checkum compared). It's not a failure inside wpasupplicant : it works both on Raspbian 9 and 10 with manual wpa_supplicant command :
