| 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:
<syntaxhighlight lang="bash">
mkdir -p /etc/crypto-policies/back-ends
echo '[hash_algorithms]
sha1 = "always"' > /etc/crypto-policies/back-ends/apt-sequoia.config
</syntaxhighlight>

| 13 || Any || Debian installer || Doesn't configure the APT-Repositories, that is appeared 2025.10 with fixing DHCP there. || <b style="color: red">ACTUAL</b>
|-
| 13 || Any || Ghostscript 10.05, kghostview || [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1131870 No way of switching to the command mode for DEVICE=x11]. The bug initially reported as "[https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1118353 Broken the main output device x11]",
but no X11 output was through complete removing the "-sInputFile" argument. After passing the input file directly there was detected other problem with switching to the command mode, which was resolved by the "-sInputFile" argument.

| 13 || AMD APU || Mesa >= 25 (Radeon) || [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1118351 Huge artifaction] on OpenGL with many messages in '''dmesg''':
<pre>
[ 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
</pre>
| '''FIXED'''
|-
| 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:
<pre>... I have forwarded your feedback to the relevant department to consider while working on our upcoming versions.</pre>
| '''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''':
<pre>
[  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
</pre>
* [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''':
<pre>
[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
</pre>
* workaround by creation a file /etc/modprobe.d/ath9k_htc.conf with the content:
<pre style="margin-left: 20px;">
options ath9k_htc use_dev_fw=1
</pre>
| '''WORKAROUND'''
|-
| >=8 || Any || GLibC || Significant degradation of the memory allocation, especially bright represented in [[Special:MyLanguage/Modules/WebVision|the module UI.WebVision]] — [[Special:MyLanguage/Modules/WebVision#Efficiency|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.
* KMix was made dynamic by the patch "[https://bugs.pearsoncomputing.net/show_bug.cgi?id=2782 kmix-UpdMixersForChangeAndChMaster.patch]".
| '''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 || [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=914999 The WIFI-adaptor does not connect].
* we need [https://github.com/Mange/rtl8192eu-linux-driver/issues/46 to append] in the file /etc/NetworkManager/NetworkManager.conf for those lines:
<syntaxhighlight lang="INI" style="margin-left: 20px;">
[device]
wifi.scan-rand-mac-address=no
</syntaxhighlight>
| '''WORKAROUND'''
|-
| >=9 || Any || WIFI Hot Spot || [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=919294 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.
| <b style="color: red">ACTUAL[>=10]</b>, '''WORKAROUND[9]'''
|-
| 13,12,10,9 || AMD APU || Radeon || [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=879992 Rebooting] or [https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1118349 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.
