[Desktop-packages] [Bug 1941752] Re: Regression: exiv2 0.27.3-3ubuntu1.5 makes Gwenview crash when opening images exported by darktable
gwenview crashes every time when I try to open any image. Not darktable related. It started after some regular apt update done a few weeks ago. I had 18.04 LTS, so decided to upgrade to latest LTS (Focal).

[Desktop-packages] [Bug 1688018] Re: DNS server from vpn connection is not being used after network-manager upgrade to 1.2.6
This bug forced me to search for ubuntu alternatives. I'm looking currently at Manjaro. About commenting out dns=dnsmasq. Doing so on laptop (LAN and wifi connections active) has this drawback: ping my_comp_name .unresloved name adding my_comp_name to /etc/hosts makes the ping my_comp_name working again, but unplagging RJ45, system changes automatically to wifi connetcion (other IP) and ping my_comp_name again is not working. With dnsmasq enabled the system nicely deals with name resolution so there are no such issues. What happens when the host name resolution is not working ok?

[Desktop-packages] [Bug 1688018] Re: DNS server from vpn connection is not being used after network-manager upgrade to 1.2.6
Almost year old bug still there. This is core functionality of any OS (secure VPNs, DNS) which just does not work on Ubuntu. I don't know how about other distros but I doubt that Ubuntu can claim to be the desktop system with such a bug. I can confirm that the simplest workaround is comment out dnsmasq in NetworkManager config (ubuntu 16.04). But there are drawbacks of course so this makes the system less secure/reliable in some situations. And of course it took me about 5 hours to figure out what is going on. Those hours could be spend more productive.
