Appendix. Known issues and their fixing status

Known issues and their fixing status
Distribution Hardware Software Description Status
Debian
13 Any APT Debian policy is demanded to disable SHA-1 in signing the repositories and it blocks such ones right now. But the project is maintaining several old repositories with the same key, so SHA-1 cannot be disabled.

To restore of working the repositories on Debian 13 you need to call such commands on your installed system, which already applied in Live Disks of the project: 

mkdir -p /etc/crypto-policies/back-ends
echo '[hash_algorithms]
sha1 = "always"' > /etc/crypto-policies/back-ends/apt-sequoia.config
WORKAROUND
13 Any Debian installer Doesn't configure the APT-Repositories, that is appeared 2025.10 with fixing DHCP there. ACTUAL
13 Any Ghostscript 10.05 Broken the x11 output, that is it show blank screen for any PDF-File. ACTUAL
13 AMD APU Mesa >= 25 (Radeon) Huge artifaction on OpenGL with many messages in dmesg: 
[ 3206.972861] radeon 0000:00:01.0: vbo resource seems too big for the bo
[ 3206.972868] radeon 0000:00:01.0: vbo resource seems too big for the bo
ACTUAL
13 Any Viber >= 24 Loss all contacts from the previous configuration.

Can be restored by copying back the "data.db" and "viber.db" files from the previous installation after resyncing (which also isn't smooth).

WORKAROUND
13 Any Viber >= 24 Loss own pictogram in the system tray.

Can be returned back with copying old version of the program (like 21.8) from Debian 12. The developer after notification just replied: 

... I have forwarded your feedback to the relevant department to consider while working on our upcoming versions.
 WORKAROUND
13,12,11,10 NVIDIA GeForce 7025 Mesa < 25 (Nouveau) Huge artifaction and sometime dead hang [10,11] on OpenGL with messages in dmesg: 
[   35.231713] nouveau 0000:00:0d.0: bus: MMIO write of 00600001 FAULT at 00b010
[   35.827377] nouveau 0000:00:0d.0: bus: MMIO write of 00620001 FAULT at 00b020
  • [12,11,10] resolved as a bug of Mesa, which workarounded by disabling acceleration in Nouveau with the Linux kernel argument "nouveau.noaccel=1";
  • [13] officially seems fixed in Mesa >= 25, but not for kernels 6.12, which are dead hanging on sleeping (6.17 doesn't hang).
 WORKAROUND
>= 11 Intel WLan Iwlwifi Unstable work with messages in dmesg: 
[36338.287415] iwlwifi 0000:03:00.0: missed beacons exceeds threshold, but receiving data. Stay connected, Expect bugs.
[36338.287425] iwlwifi 0000:03:00.0: missed_beacons:23, missed_beacons_since_rx:3
  • workaround by creation a file /etc/modprobe.d/ath9k_htc.conf with the content:
options ath9k_htc use_dev_fw=1
WORKAROUND
>=8 Any GLibC Significant degradation of the memory allocation, especially bright represented in the module UI.WebVision — the problem analyzing.
  • the problem is a disadvantage of the memory allocation arenas linked to threads, which causes to such sort inter-arenas memory fragmentation on high dynamic using, what recreates the threads. As a workaround there is globally used the environment variable MALLOC_ARENA_MAX=1 to set the arenas number to 1!
 WORKAROUND
10 Any KMix Missing PulseAudio. FIXED
>=8 Any Plymouth The console starting splash images locks the first screen of the console and does not stop with "systemd", so /var/boot.log grows indefinitely.
  • TDM switched in the SDM mode then plymouth stops now after TDM start.
 FIXED
11,10,9 RTL8192EU WLan The WIFI-adaptor does not connect.
  • we need to append in the file /etc/NetworkManager/NetworkManager.conf for those lines:
[device]
wifi.scan-rand-mac-address=no
WORKAROUND
>=9 Any WIFI Hot Spot Does not work, tested with Nokia N9.
  • resolved as a regression or the security level rising in wpasupplicant of the version 2.4 (or OpenSSL 1.1) — workaround by the downgrading to version 2.3.
 WORKAROUND[9], ACTUAL[>=10]
13,12,10,9 AMD APU Radeon Rebooting or dead hang just in the Linux kernel boot, detected on AMD A8-6500 APU.
  • resolved as a bug of the video driver Radeon in enabling DPM by default. Workarounded by the Linux kernel argument "radeon.dpm=0" and that applied in task-tde-desktop 1.2-7 also for fixing in the installed systems from those Live Disks;
  • officially fixed in Linux kernels version 5 and broken again in 6.
