Ubuntu 21.04 - Ubuntu Software not opening

pf flag

Yesterday Ubuntu Software was working but today it isn't. Running snap-store shows the following error

/snap/snap-store/518/usr/bin/snap-store: symbol lookup error: /snap/snap-store/518/gnome-platform/usr/lib/x86_64-linux-gnu/libgtk-3.so.0: undefined symbol: atk_plug_set_child

These two updates happened since the last time it worked (yesterday that I installed Spotify)

I've tried re-installing the snap-store and gnome-3-34-1804 but it didn't work.

Try to install the candidate version. It worked for me.

snap remove snap-store
snap install snap-store --candidate

Note: After bug 1931380 gets fixed, you will need to switch back to the default channel.

Update: the default channel has fixed the bug. You should automatically get the stable refresh within 24 hours. If you switched to the candidate channel, you will need to switch back to default.

$ snap refresh

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
