Aptitude 0.8.10: log report
Fri, Jan 17 2020 10:37:15 +0300
IMPORTANT: this log only lists intended actions; actions which fail
due to dpkg problems
I have installed both xserver-xorg-video-amdgpu-hwe-18.04 and xserver-
xorg-video-ati-hwe-18.04
$ aptitude show xserver-xorg-video-amdgpu-hwe-18.04
Package: xserver-xorg-video-amdgpu-hwe-18.04
Version: 19.0.1-1~18.04.1
New: yes
State: installed
Automatically installed: yes
Priority: optional
After downgrade packages, error is gone
Old versions that correct works:
libdrm2_2.4.97-1ubuntu1~18.04.1_amd64.deb
libdrm2_2.4.97-1ubuntu1~18.04.1_i386.deb
libdrm-amdgpu1_2.4.97-1ubuntu1~18.04.1_amd64.deb
libdrm-amdgpu1_2.4.97-1ubuntu1~18.04.1_i386.deb
I can confirm bug fix with new packages from ppa.
After upgrade only two packages
xserver-xorg-video-amdgpu-hwe-18.04:amd64 from 19.0.1-1~18.04.1 to
19.0.1-1ubuntu1~18.04.1
and
xserver-xorg-video-ati-hwe-18.04:amd64 from 1:19.0.1-0ubuntu1~18.04.1 to
1:19.0.1-1ubuntu1~18.04.1
bug still
* xserver-common:all from 2:1.19.6-1ubuntu4.3 to
2:1.19.6-1ubuntu4.4~ppa1
