Estou tentando fornecer um backtrace para travamentos repetidos do KDE Discover, mas não consigo encontrar (muito menos instalar) os arquivos de depuração necessários.
Tentei encontrar símbolos de depuração para o Discover adicionando os seguintes repositórios às minhas fontes de software:
deb http://ddebs.ubuntu.com jammy main restricted universe multiverse
deb http://ddebs.ubuntu.com jammy-updates main restricted universe multiverse
deb http://ddebs.ubuntu.com jammy-security main restricted universe multiverse
deb http://ddebs.ubuntu.com jammy-proposed main restricted universe multiverse
conforme recomendado neste tópico:
Como instalar símbolos de depuração para pacotes instalados?
No entanto, fui solicitado a atualizar o cache, o que produziu a seguinte mensagem de erro:
Could not refresh cache

Eu executei o "sudo apt install ubuntu-dbgsym-keyring" recomendado, mas ainda não consigo encontrar ou instalar os símbolos de depuração do Discover para permitir um rastreamento do problema.

Primeiro, adicione a chave GPG ausente:
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com C8CAB6595FDFF622
sudo apt update
tente instalar os símbolos novamente.

Estou postando isso como uma resposta, embora não seja, porque é muito longo para um comentário.
@Jorge O primeiro comando acima rendeu:
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).
Executing: /tmp/apt-key-gpghome.qiNcMjEc9W/gpg.1.sh --recv-keys --keyserver keyserver.ubuntu.com C8CAB6595FDFF622
gpg: key C8CAB6595FDFF622: "Ubuntu Debug Symbol Archive Automatic Signing Key (2016) <[email protected]>" 2 new signatures
A execução do segundo comando aparentemente atualizou todos os repositórios recém-adicionados, exceto um:
Err:13 http://ddebs.ubuntu.com jammy-security Release
404 Not Found [IP: 185.125.190.17 80]
Get:14 http://ddebs.ubuntu.com jammy-proposed Release [40.5 kB]
Reading package lists... Done
E: The repository 'http://ddebs.ubuntu.com jammy-security Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
No entanto, ainda não consigo encontrar nenhum pacote "dbgsym".
